1 Answer

Answer :

Classification of hydro-electric power plants according to water flow regulation of water flow:- 

1. Large reservoir power plant 2. Run-off river (ROR) power plant with poundage 3. Run-off River (ROR) power plant without poundage 

1. Large reservoir power plant:-  These plants have large reservoir by constructing large dam Surge tank is compulsory. It has large generating capacity. Initial cost is high The main purpose of this plant is to generate electricity.

2. Run-off river (ROR) power plant with poundage:-  These plants store water in poundage by constructing small dam Fore bay acts as a surge tank Generating capacity of these plants depends upon size of poundage Initial cost is medium The main purpose of such power plant is to store water mainly for drinking,agricultural purpose and secondary purpose is to generate electricity.

3. Run-off River (ROR) power plant without poundage:-  These plants do not store water. No surge tank Generating capacity of these plants depends upon rate of flow of water Initial cost is less Its purpose is to generate electricity.
