SSR Mitigation and Analysis for DFIG Based Windmill Using STATCOM Controller

  • Dr. R. Tamilselvan

Abstract

Large-scale network integration has resulted in a number of challenges, including the requirement of increased power transport capacities without affecting the voltage. The Doubly-Fed Induction Generator (DFIG) wind turbine will be used for the transmission of power to large distances, and the simulation is carried out via a MATLAB Simulink. The results will then be validated. DFIG wind turbine is in normal operating condition. Due to the Sub Synchronous Resonance series compensation, which is very damaging to the wind generator due to the variation in frequency, the machine mechanics of the generator are damaged. If any part of the study system in any bus line has experienced a major disturbance, the effect of SSR is harmer. SSR's impact depends on the percentage of compensation we used for serial compensation. The use of FLACTS devices such as STATCOM, SVC, and SSSC can be mitigated to mitigate SSR. Due to its high stability, low switching loss and variable voltage rating we use STATCOM. Whenever disturbances happen in the transmission line, STATCOM acts through reactive power and real power absorption, thereby maintaining the system's stability. For action, such as real power absorbance or reactive power injection, the STATCOM controller gives the STATCOM pulsation. This protects the wind turbine and preserves the stability of the system.
