Abstract

With the increase of wind power penetration,the traditional strategy,which resects wind turbines when power grid voltage drops,does not meet the requirements for grid security and stability,so new rules require wind turbines connecting to grid must have the capability of low voltage ride-through,meanwhile provide some reactive power.This paper introduces several Crowbar circuits which are used for direct drive wind power system.By comparison,resistance to unloading Crowbar circuit of DC side is selected for realizing the low voltage ride-through,acting in concert with the network side of the inverter.The simulation result shows that unloading resistance with the network side inverter controlling can effectively improve the capability of the low voltage ride-through of the direct drive wind power system.
