Question
A hydel power plant produces 18x103 kW under a head of 14 metres. Determine thefollowing(a) Type of turbine(b) Synchronous speed of generator,Assume overall efficiency of plant is 70%
Solution
(a) Type of Turbine: The type of turbine used in a hydel power plant is typically determined by the head of the water, which is the height from the surface of the water to the turbine. In this case, the head is 14 meters. This is considered a low head. Therefore, the type of turbine used is likely a Kaplan turbine, which is designed for low head applications.
(b) Synchronous Speed of Generator: The synchronous speed of a generator in a hydel power plant is determined by the frequency of the electrical grid and the number of poles in the generator. However, without this information, we cannot determine the synchronous speed of the generator.
The overall efficiency of the plant does not affect the type of turbine used or the synchronous speed of the generator. It is a measure of how effectively the plant converts the potential energy of the water into electrical energy. In this case, the plant is 70% efficient.
