摘要
Abstract
In wind power system, the grid voltage and load current would disturb the grid-connected inverter at the same time when the grid voltage drops down. Then the DC-link voltage is difficult to maintain stability , which would further influence the system stability and restore ability. To improve low voltage ride through capability in wind power system,an improved method was put forward based on the balance of grid side power and load side power which can dynamically change the gain coefficient of the current feed-forward to resist both grid voltage and load current disturbance. The simulation results confirm the validity and present good dynamic and static performance.关键词
