Hydraulic Turbines A hydraulic turbine is a machine which converts the pressure and kinetic energy of water called hydraulic energy into mechanical energy. These are also called as water turbines. The mechanical energy of turbine is further converted into electric energy by an electric generator which is directly coupled to the shaft of hydraulic turbine. … Read more

Interconnected System between Hydro and Steam Power Plants Hydro-electric power plants can be used both as base load and peak load plants. However, today the trend is to use hydro power plants with steam plants in an interconnected system to as follows : (a) When the adequate flow of water is available then the hydro … Read more

Preventive Maintenance of Hydro Power Plants Preventive maintenance of any power system is the key for long life and reduced break down. It enhances the power output and reduces the cost of power generation. Following is the schedule of maintenance. Monthly maintenance : Check for leakages, servo meter connections, turbine shaft, lubrication, oil pump and … Read more

Plants Based on Quantity of Water Available Run-off river plants without pondage : These type of hydro plants do not store water and use the water directly taken from the river. Since there is no control on the availability of water from the river, the power output of such plants fluctuates widely, hence, the utility … Read more

Plants Based on Type of Loads Base load plants : These type of hydro power plant can take up load on base portion of load curve of the power system. These plants are generally of large capacity to meet almost the constant load. The runoff river and storage type plants are used as base load … Read more

Plants Based on Availability of Head Low Head Plants : Hydro power plants are called as low head plants in case the available water head is less than 30 meters. In such plants the water is stored by constructing a dam across a river and the power plant is constructed at the base of the … Read more

Conduits (Canal, Flumes, Tunnel, Pipe line, Penstock) A headrace is a channel which leads the water to the turbine and the tail race is a channel which leads the water from the turbine to the river. Combination of various types of conduits are shown in Figure these are as follows : Canal : It is … Read more

Type of Spillways As indicated above, the spillways are provided to discharge the flood water during rainy season if the water level rise above the designed maximum level in the reservoir. It saves the dam from damage. Types of Spillway are : Solid gravity or overall spill way Chute or Trough spillway Side channel spillway … Read more
