INTRODUCTION
Micro-hydro power is a type of Hydro electric power that typically produced up to 100 kW of electricity using the natural flow of water. These type of power plant can provide power to an isolated home or a small community. Micro-hydro system complement solar energy because in many areas in winter the water flow is maximum and solar energy is minimum. In such areas micro-hydro power is used along with photo voltaic solar energy.
VARIOUS COMPONENTS
Construction of a Micro-hydro power plant is site specific. It is made up of a number of components. Some of them are……
Intake
Canal
Penstock
Turbine
Generator
Controlling unit
TURBINES
Turbines converts the flow and pressure energy into mechanical energy. Turbines are basically of two types i.e. Reaction & Impulse and Depending upon the head of the available water further divide in three categories i.e. High, Medium & Low head.
According to site specification (i.e. head and flow) we choose the turbine to use in micro- hydro power plant.
GENERATORS
The standard generators used in micro hydro power projects are the synchronous generator and the induction motor used as a generator.
Induction generator :- Induction generator usually an induction motor. Which rotates 1-5% faster then synchronous speed so that it can achieve negative slip, to run in generating mode.
Future of micro-hydro power plant
New computerized control systems and improved turbines may allow more electricity to be generated from existing facilities in the future.
Small scale and low head hydro capacity will probably increase in the future. Low head turbines, and standardized turbine production, lowers the costs of hydro-electric power at sites with low heads.
Conclusion…
Micro-hydro power plant is an important part of world’s electricity supply. Specially in remote areas it is providing reliable and economic source of electricity.
As no fossil fuel required in hydro power plant, it can help to save other source of energy.
