Stability Analysis of Wind Farm Based on DFIG with STATCOM

The power system defined these days is highly capable and complex so that they can satisfy the demand of the users over the power system. One of the complex form of power system is wind turbine based systems. These systems having the turbine motor with fixed or the variable speed. With all these power systems, the common problem and requirement is the voltage stability. The stability requirement is more crucial if some fault occur over the system. In such case some dynamic mechanism is required to maintain the steady state of the power system and to achieve the stability over the system so that equalize distribution of power will be done in the defined area. This paper presented the use of a DFIG based power distribution system in which the power is been generated by variable speed wind turbine. The presented system included a STATCOM based controller to achieve the stability if some fault occurs over the system. In this work, one of the crucial faults is been handle called three phase fault. This fault is here associated with the bus system. The voltage stability is been achieved by using the STATCOM based controller. The obtained result shows that the presented system achieved the voltage stability successfully.
