Simulation of Simple Standalone Wind Energy System

The main problem with wind power system is that it has to ensure power supply in spite of large variations of power generation caused by the stochastic nature of wind, while maintaining frequency and voltage with in tire permissible limits. This paper considers a small scale stand alone wind energy system using Permanent Magnet Generator, which are an important alternative source of electrical energy, finding applications in rewrote areas where conventional generation is not feasible. A comprehensive closed loop system together with converter-inverter, a batten bank suitable for different load is si mulated using Pspice. The voltage variations are caused due to fluctuations in wind speed The effectiveness of the system in restoring voltage during disturbances are simulated for different loads, with open loop and closed loop system employing error correction with respect to the reference voltage.
