- Engine Light ON (or Service Engine Soon Warning Light)
Line pressure is electronically controlled by the Transmission Control System (TCM) and is measured by the Line Pressure Sensor (LPS). The desired line pressure is continuously being compared to the actual line pressure and is regulated by electronically changing the duty cycle of the Pressure Control Solenoid (PCS). The Transmission Control System calculates the desired line pressure based on inputs from the transmission and engine. A calculated torque input to the transmission is used as the primary input to the desired line pressure calculation and is called Torque Based Line Pressure. The Transmission Control Module (TCM) monitors the Hydraulic Pressure Sensor. The TCM sets the OBDII code when the Hydraulic Pressure Sensor is not to factory specifications.

Alstom Projects India Ltd has won three major contracts worth over Rs 270 crore (over €40 million) to build hydroelectric projects in the country. The first contract has been signed with Shiga Energy Pvt Ltd for the 97 MW Tashiding hydroelectric project in West Sikkim district on the Rathang Chu river. The second contract has been signed with NSL Tidong Power Generation Pvt Ltd for the Tidong 1 hydroelectric project in Kinnaur District in Himachal Pradesh, consisting of two 50 MW units. The third contract has been signed with Haridwar Infrastructure Pvt Ltd for the Dikchu hydroelectric project on the river Dikchu, a tributary of Teesta River in East Sikkim, for a 96 MW plant.
All equipment will be manufactured at Alstom’s Vadodara facility in Gujarat, one of the company’s largest hydro equipment manufacturing hubs worldwide. Alstom estimates that India has an economically exploitable and viable hydro potential of about 84,000 MW. However, only 19.9 per cent of this potential has been harnessed so far. Additional hydropower capacity would diversify India’s energy mix, currently reliant on fossil fuels, thus contributing to energy security and reducing greenhouse gas emissions.
These three contracts follow a major contract won by Alstom with Tehri Hydro Development Corporation (THDC) to install the 1,000 MW Tehri variable speed pumped storage hydro power plant in Uttarakhand. Alstom projects currently under execution include the 2,000 MW Subansiri Lower hydroelectric power plant in Assam and Arunachal Pradesh, India’s largest hydro project.crackcrack

Customized Precision Lost Wax Casting Pump Valve Parts Impeller For Pump
The impeller of water pump is made of casting. The blade on the pump impeller plays an important role. The shape and size of the pump impeller are closely related to the pump performance. Pump impeller can be generally divided into single suction type and double suction type, single suction impeller for single side suction, small flow pump impeller for this type. Double suction impeller for both sides of the suction, large flow pump impeller are used double suction impeller.
1,What is a pump impeller?
The rubber impeller provides cooling water to the cooling system by sucking in the water from the water inlet and leading it to the water outlet of the water pump... And if the water pump is overheated, the performance of the engine will be reduced.
2,Is pump and impeller the same thing?
Popularly speaking, the impeller is the rubber material inside the pump, which is used to promote the water flow. The water pump is a complete assembly. Unless the gasket, O-ring, etc. are damaged or the housing is damaged, it is usually only necessary to replace the impeller.
3,How do I know if I need a new impeller?
When the impeller needs to be replaced, the internal temperature of the motor rises, and the equipment stops sucking cooling water and extracting warm water. This eventually leads to overheating, leaving a distinct charring mark on the motor.

Polavaram hydroelectric project (PHEP), also known as Indira Sagar project, is a 960MW multi-purpose project being constructed on the Godavari River near Polavaram village in the East Godavari and West Godavari districts of Andhra Pradesh, India.
Being developed by Andhra Pradesh Power Generation Corporation (APGENCO), a state-owned power generation company, the project will provide hydropower, irrigation, and drinking water to East Godavari, Vishakhapatnam, West Godavari, and Krishna districts in Andhra Pradesh.
In addition to power generation, the hydroelectric power project is expected to supply water to 0.72 million acres of land for irrigation and 23.44 thousand million cubic feet (tmc) of drinking and industrial water to Visakhapatnam. It will lift 80 tmc of water to the Prakasam Barrage on Krishna river and will also meet the drinking water needs of 540 villages in the Polavaram project command area via canals.
Background of the Polavaram project
The technical advisory committee of Ministry of Water Resources, River Development and Ganga Rejuvenation (MoWR) accepted the project proposal in January 2009. The project received the initial investment clearance for Rs101.51bn ($2bn) from the Planning Commission, a central government agency, in February 2009.
The central government formed the Polavaram Project Authority (PPA) under the MoWR for the regulation and development of the project in May 2014. The estimated investment in the project has been revised to Rs555.48bn ($7.7bn) in 2019.
Polavaram hydroelectric project details
The PHEP development involves the installation of 12 units of Kaplan hydro turbines, each with 80MW capacity.
The main reservoir includes three critical divisions, comprising gap, spillway, and earth-cum-rockfill dam. Gap-1 will feature a 450m-long earth-cum-rockfill dam, while Gap-2 will have a 1.75km-long earth-cum-rockfill dam. Gap-3 will be a 150m-long small concrete dam. Preliminary tests for rockfill dam and work for coffer dam at the upper and lower end of the project were completed by February 2020.
The 1.054km-long reservoir spillway will feature 53 blocks, each with a height of 55m and a total concrete work of approximately 0.25 million cubic metres. The spillway will be installed with the advanced heaviest-of-its-kind hydraulics system gates, for which the placement of the girders on the spillway began in July 2020.
The catchment area for the project is approximately 306,643km² with a design flood discharge of 0.102 million cumecs (3.6 million cusecs). The dam will have the full reservoir level at +45.72m (+150.00ft) with a gross storage of 5.511 T.M. Cum. (194.6tmc) in the reservoir.
The length of the left main canal will be 181.50km while the right main canal will be 174km long.
A total of 196 girders, each weighing approximately 62t, will be erected on the piers of the spillway.
Heavy machinery such as Telebelt-200, Boom placers to perform concrete works up to 62m height and hydraulic rigs to dig up to 50m depth have been deployed at the project site. The entire project will require a total concrete work of 0.307 million cubic metres.
Other works such as project coating, surface dressing, and completion of roads are expected to be completed by August 2021.
Power supply details
The Central Electricity Authority granted approval for two 400KV doubled circuit (D/C) quad lines, namely Polavaram-Guddigudem and Polavaram-Eluru lines, for the transmission of power from PHEP.
Transmission Corporation of Andhra Pradesh (APTRANSCO) submitted an investment proposal for the power evacuation scheme in February 2020. The project will generate approximately 3,100 million units of electricity annually.
Megha Engineering and Infrastructures Limited (MEIL) was awarded an engineering, procurement, construction (EPC) contract worth Rs43.58bn ($618.6m) for the Polavaram project in a reverse tendering process in November 2019. It is working in collaboration with the Andhra Pradesh state government for the development of the project.
MEIL contracted Bharat Heavy Electricals Limited (BHEL) to supply hydro turbines and perform electro-mechanical works for the project in December 2020. BHEL’s work includes designing, engineering, manufacturing, supply, and supervision of erection, as well as testing and commissioning of the equipment and related auxiliaries.
The project contract was earlier awarded to Navayuga Engineering Company. It was, however, revoked after the new state government overhauled the contract process and sought to hire new contractors under the reverse tendering process in a bid to ensure transparency and reduce project costs. Infrastructure and construction company Transstroy India was also involved in the project.

Melamchi, Dec 28Â : Though it has been announced that Kathmandu dwellers would get drinking water from Melamchi within Baishakh 1, 2073 BS, there is slim chance of the Melamchi project meeting its deadline due to delay in construction works.
According to the Melamchi Drinking Water Project, out of 20 kilometers of the main canal, only three kilometer canal has been constructed so far.
Except this, six-kilometer of sub-canal has been constructed. Only 17 per cent construction works have been constructed so far.
The project added that around 83 per cent construction works is still remaining. The total length of the canal is 26.5 kilometers.
Director at the Melamchi Drinking Water Development Committee, Ghanshyam Bhattarai, however said that they would leave no stone unturned to complete the project in deadline.
He said, “We are hopeful that the construction works of the canal would be completed on time.”
It would be difficult to complete the construction works of the canal after constructing 40 meters daily, but only 20 meters of canal is now being constructed daily.

An analysis of the Cahora Bassa Dam Water Balance and Reservoir Operations and their Flooding Impact on Upstream Settlements
MetadataShow full item record
The Lower Middle Zambezi catchment is sandwiched between three major dams; Kariba, Kafue (Itezhi-tezhi) and Cahora Bassa. The upstream dams have an impact on the inflows in the downstream Cahora Bassa Dam and, also, on the area inundated upstream of the Cahora Bassa. This study aimed at estimating the water balance of the Cahora Bassa using available meteorological and hydrological data sets such as rainfall, temperature and runoff for the period 1980 to 2010. The flow data analysed includes the discharge from the Kariba, Kafue and Cahora Bassa dams and river flows for Luangwa, Chongwe, Musengezi and Manyame. Missing flow data was generated using regression and mean value infilling methods. GIS was used to calculate the isohyets for the average annual rainfall in the lake drainage basin using the nearest neighbour interpolation technique. GIS was further used to process the Digital Elevation Model (DEM) of the study area through the DEM hydroprocessing algorithm in ILWIS thus establishing the ungauged catchment area of the lake. Two gauging stations were installed at Manyame Mapomha and Angwa Bridge on the Manyame and Angwa rivers, respectively, as part of the project’s effort of moving from ungauged to gauged flow. The results from these stations were however too short to give any meaningful indications as to the discharge from the associated catchments. As a result, a hydrological model, the HEC-HMS, was then used to simulate runoff from the ungauged catchments which showed that these areas contribute about 12% of the total estimated inflows into the Cahora Bassa Dam. The average flow for one hydrological year revealed a total inflow of 71.73 x 109 m3/year, total outflows averaged 52.25 x 109 m3/year and a residual storage of 20 x 109 m3/year. While the high flood level for the Cahora Bassa Dam lies at the 329 masl contour line, which translates to an inundated area of 3,246 km2, the actual maximum water level for the period considered (1980 - 2010) reached only 328.18 m contour thus giving an inundated area of 2,920 km2. Analysis of the river flow hydrographs and the associated lake water level indicates that there is a close link between reservoir operations and flood occurrence in Luangwa, Kanyemba and Muzarabani areas. The flooding effect of the reservoirs is only felt when the water level in the Cahora Bassa Dam is above 324. The study concludes that the ungauged lower middle Zambezi contributes a significant amount which averages 8.5 x 109 m3/year, which is about 12 %of the total inflows into Cahora Bassa while the gauged flows from the Kariba, Kafue, Luangwa, Chongwe, Manyame and Musengezi contribute about 85 % of the total flows into the Cahora Bassa. The remaining 2.5 % comes from direct rainfall on the lake surface. Furthermore, the study showed that flooding is most likely when high water levels are accompanied by high flows in the associated rivers such as the Luangwa, the Mwanza Mtanda and the Musengezi.

A reserved running centrifugal pump can work as a hydraulic turbine with its wide application in industrial energy recovery and the development of micro-hydraulic power. In order to improve the efficiency from the point of turbine working condition, the impeller with forward-curved blades was designed and the hydraulic performances were further analyzed based on the commercial software ANSYS CFX 12.0 in this study. Moreover, to improve the computational accuracy of numerical simulations on turbines, the grid number, the turbulence model, the circumferential flow distribution in the clearance between the volute and the impeller as well as the grid distribution in the boundary layer were considered.
According grid independency analysis, the 1.2 million grids’ number was assumed for numerical simulations. Considering the consuming time and computational stability, as well as the accuracy of the CFD calculation, the k–ε turbulence model was chosen for further calculations. The shaft power and the efficiency of the turbine were more close to the experimental data as the whole computational flow domain in the clearance between the volute and the impeller was connected on the impeller domain. Compared with the performance curves with or without grids in the boundary layer, the boundary layer with grids used in the PAT during numerical simulations was more close to the experimental one.
Compared with the experimental data, the H-Q curves of the hydraulic performances of the turbine with forward-curved blades predicted by CFD were positioned under the experimental one. With respect to the efficiency of the turbine, the various ranges of the efficiency is less than 5%, even there is some deviations between the CFD and experimental results. Therefore, the good agreement of the hydraulic performances between CFD and experimental results in present study indicates that the proposed numerical methods can adequately capture the internal flow in a hydraulic turbine with forward-curved blades, and can also provide a reliable reference for the design of hydraulic turbines.

Laboratory model experiments can be used to verify the applicability and accuracy of a new hydrogeological test method. The unsteady-flow pumping test is the most commonly used comparison method. The axisymmetrical circular aquifer model is frequently used in laboratory model experiments. However, the scale of the laboratory experiment model is always finite, which increases the influence on the test calculation results when using conventional Theis theory. Here, based on analytical analysis and laboratory experiments, a new calculation method is proposed for the circular constant water-head boundary of finite scale. The proposed method can eliminate the effect of the finite-scale circular constant water-head boundary on the unsteady pumping test results and can also be applied to large-scale circular constant water-head boundaries. Geotextiles are permeable fabrics; therefore, the hydraulic conductivity of a geotextile can be used to simulate the hydraulic conductivity of a fractured aquifer. A geotextile test, steady pumping test and slug test were conducted to verify the accuracy of the proposed calculation method, with all the results indicating that the proposed method can provide more accurate hydrogeological parameters from an unsteady pumping test with a circular constant water-head boundary of finite scale than conventional Theis theory for unsteady pumping tests.

- Application of an optimization/simulation model for the simulated real-time flood control for river-reservoir systems to the catastrophic May 2010 flood on the Cumberland River at Nashville, Tennessee is described. The optimization/simulation model includes five major components, including a hydrologic rainfall-runoff model, a hydraulic unsteady flow model, a short-term rainfall forecasting model, a reservoir operation model, and a genetic algorithm optimization model. The model application revealed that the reservoir upstream of Nashville was more contained and that an optimal gate release schedule could have decreased the floodwater levels in downtown Nashville below the 100-year flood stage. The application is for demonstrative purposes only, but does reflect the suitability of the optimization/simulation model for real-world application.

Titulo: 1D and 2D numerical models coupling for a flood simulation in the Tiber river
Universidad de Zaragoza, Universita La Sapienza di Roma, 2007-2008.
Acciones Integradas España-Italia, Ministerio de Educación y Ciencia
Flood wave propagation along rivers is significantly influenced by the storage capacity of floodplains and river beds. In order to correctly reproduce the reduction of the peak discharge along the water course, the inundation of floodplains must be carefully simulated. In order to map the flood prone areas, it is common practice to apply 1D mathematical models to simulate the propagation of flood waves in long reaches. This schematization results acceptable if the width of the floodplain is comparable with the main channel width, but if the bottom valley is very wide, a simulation by means of a 2D mathematical model could be more appropriate. However, the application along the water course (30-40 km long) of a fully 2D model could result very burdensome since rarely digital elevation models (DEM) are available with sufficient detail to reproduce river bathymetry. In this case a coupled simulation of both 1D and 2D models seems useful. In this way, the propagation in the main channel will be simulated by means of a 1D model and the inundation of the riverside will be simulated by means of a 2D model. However, the two models can not be applied in cascade since the water depth in the floodplain influences the water exchanges between main channel and riverside. The aim of this research is to develop and apply to a case study a coupled simulation of both 1D and 2D model in order to simulate in a more correct way the storage capacity of the bottom valley, to compare the results obtained by means of a coupled simulation with those obtained by means of a fully 1D model and to identify the limits of application of 1D models.

A Simulation Model for Stage –IV Koyna Hydropower Plant
Mohd. Imran Ahmed, Siraj Y. Abed
Department of Industrial Engineering, King Abdulaziz University,
Hydroelectric power contributes around 12.45 percent of the electricity supply in India. It is considered to be the most vital, unpolluted, emission-free and an inexpensive renewable source of energy. Hydroelectric power-plants operating all over the world aims to have high electric output with minimum maintenance cost. It’s very different with Koyna Hydropower Plant (KHPP) stage IV which generates lower electric output than the installed capacity with higher maintenance. This project aims to build a simulation model which can simulate the regular operation of Koyna Hydropower Plant with Arena®. The study involves to evaluate dynamic response of the system and plant performance under various operating conditions such as head height, quantity of water flow penstock and operating gates. Also to determine and identify the optimum parameters required for maximum power generation. The outcomes of the model helped to analyse the power generation capacity against the required quantity of water flow and head height. The developed simulation model was validated and used as an apparatus to determine the optimal operating parameters that maximise power generation of stage –IV at Koyna Hydropower plant.

Three Gorges Dam
The Three Gorges Dam is a hydroelectric river dam that spans the Yangtze River in the town of Sandouping,in Yichang, Hubei province. It is the world's largest electricity-generating plant of any kind. The dam body was completed in 2006. Currently, it contains 32 main generators, each with a capacity of 700 MW. Six additional generators in the underground power plant are being installed and are not expected to become fully operational until around 2011. With 2 small generators (50 MW each) to power the plant itself, the total electric generating capacity of the dam will eventually reach 22,500 MW. The project produces hydroelectricity, increases the river's navigation capacity, and reduces the potential for floods downstream by providing flood storage space. From completion until September 2009 the dam has generated 348.4 TWh of electricity, covering more than one third of its project cost.
The project management and the Chinese state regard the project as a historic engineering, social and economic success, a breakthrough in the design of large turbines, and a move toward the reduction of greenhouse gas emissions. The total estimated cost of the project ranges from $20 billion to $25 billion, and both international and Chinese tourists have turned out in droves to view the structure.
The reservoir will open the country's remote interior to new trade routes, allowing large freighters to sail an additional 1,500 miles inland to the developing commercial hub of Chongqing.
