Simulation Research of LVRT in Wind Power Grid-Connected System Based on RT-LAB
摘要
Abstract
In order to solve the problem of the low voltage ride through (LVRT) in wind power grid-connected system of a direct-drive wind turbine with permanent magnet synchronous generator,at the DC side in wind power grid-connected system,a super capacitor is added through bidirectional DC-DC converter.The fast charging and discharging characteristics of the capacitor is used to improve the stability of the DC bus voltage and achieve the LVRT.What's more,this paper built the wind power grid-connected system model based on the RT-LAB real-time simulation software.The results of the simulation demonstrate the effectiveness of the scheme. At the same time, the real-time simulation software of RT-LAB was used in wind power grid-connected system LVRT and the experiment research was done. The results show that the simulation can well reflect the dynamic characteristics of the wind power grid system, and is of great significance in both the evaluation of the dynamic equivalent model of wind power grid system and the controller development of wind power grid system.关键词
