| Abstract: | This paper establishes the model of doubly-fed induction generator,and the operation principle of static syn-chronous compensator(STATCOM) is researched as well as the main circuit structure.According to cascade H-bridge multilevel STATCOM,sampling time staggered SVM(STS-SVM) is proposed to control the H-bridge STATCOM.When power grid voltage sags happen,simulations on compensation characteristics of STATCOM are studied.The results illus-trate that the reactive power of wind farm can be compensated effectively,and the voltage stability of wind farm can be improved.At the same time,cascade H-bridge multilevel STATCOM improves the low voltage ride through capability. |
