摘要
随着我国风电穿越技术的飞速提升,低电压穿越作为电力行业热点备受关注.文章根据国网的低压穿越标准,阐述了风电设备的低电压穿越要求,解析了电网电压骤降时DFIG的动态特性,介绍了硬件的布局设计,结合DBR、Crowbar及转子电流续流二极管等,辅以主控系统及网侧、机侧变流器的低穿控制算法进行模拟验证.仿真试验结果表明,该低电压穿越策略可有效保障电网的持续稳定运行.
Abstract
With the rapid improvement of wind power traverse technology in China,low voltage traverse has attracted much attention as a hot spot in the power industry.According to the low voltage crossing standard of the State grid,this paper expounds the low voltage crossing requirements of wind power equipment,analyzes the dynamic characteristics of DFIG when the grid voltage plunts,introduces the layout design of the hardware,combines DBR,Crowbar and rotor current continuous diode,and simulates the low crossing control algorithm of the main control system and the converter on the grid side and the machine side.The simulation results show that the low voltage crossing strategy can effectively guarantee the continuous and stable operation of power grid.
