SIMULATION OF IMPROVEMENT OF POWER QUALITY USING STATCOM-CONTROL SCHEME WITH GRID CONNECTED WIND ENERGY SYSTEM

The use of wind energy generation in electrical gri d is increasing worldwide. Injection of the wind power into an electric grid affects the power quality. The generated wind power is always not constant due to its time varying nature and causing stability problems. This weak interconnection of wind generating source in the el ectrical network affects the power quality and reliability. In this paper the power quality pr oblem due to installation of wind turbine with the grid is determine. In this proposed scheme Static Compensator (STATCOM) is connected at a point of common coupling to reduce t he power quality problems. The STATCOM gives reactive power support to wind genera tor and also load. The proposed system maintains the grid voltage free from distort ion and harmonics. In this paper the effect of STATCOM is presented. The behavior of STATCOM is studied under reactive l oading condition.
