A theoretical analysis of controlling the speed of wind turbine and assemblage of solar system in the Wind Energy Conversion system

Abstract

In order to meet the ever increasing demand of electricity, renewable energy such as Wind Energy can be a viable option in generating a substantial amount of electricity. This paper leads to pick the best possible method between VSCF (Variable Speed Constant Frequency) and CSCF (Constant Speed Constant Frequency) of Wind Energy Conversion System (WECS) because of experiencing tremendous growth of this scheme in recent time. Besides, IGBT inverter has the demonstration of so called “short-circuit withstanding capability” which ensures the withstanding of severe condition by preventing large short circuit current. A speed control system which comprises speed controller, actuator model and the turbine linearized model is proposed which can be used to stabilize the frequency through speed control. In addition the implementation of solar cell in WECS has also been proposed which can ensure more effective and relatively stable output power.
