摘要：In this paper, a standalone electric generating system for remote locations is discussed. A typical micro hydro site layout and photograph which shows how the hydro power can be extracted is given. The three phase induction motor is used as a generator for producing three phase output by providing excitation through three capacitors connected in shunt. The design of the capacitor in a simple way is shown. To consume the excess power in the system an Electronic Load Controller (ELC) is used which will maintain the voltage and frequency within limits. The selection of components for ELC with the chosen device ratings is tabulated. Simulation was done on Matlab/Simulink using the Fuzzy Logic Controller. The membership functions and rules of the fuzzy controller are presented. The various models with the output waveforms are represented and discussed. It is shown that when the ELC is used, the output voltage and frequency remains within the limits when the load is changed from 300W to 600W. The experimental setup uses a separately excited DC motor coupled to a 1 H.P squirrel cage induction motor running at a speed above synchronous speed of the induction motor. Circuit diagrams, ratings and photographs of the experimental setup are provided. Drawbacks of the discussed system are enumerated and possible solutions and enhancements are briefed.
