| 摘 要： | 针对风电机组低电压穿越能力的要求,在分析Crowbar电路和串联制动电阻(SDBR)保护原理的基础上,提出利用两种方式结合的方法来改善双馈风电机组的低电压穿越能力。利用Matlab/Simulink仿真平台建立基于双馈风力发电机的风电系统仿真模型,并将仿真结果同不加任何保护装置的风电系统各参数进行对比。结果表明,改进的保护措施能有效保护风电机组,提高机组的低电压穿越能力。

| Abstract: | To study the wind turbines low voltage ride through ability, based on analysis of the protection principle of Crowbar circuit and series dynamic braking resistor （SDBR） ,two ways are proposed to be combined to improve the ability of doubly-fed wind power genera- tor in the low voltage ride through. The wind power system simulation model of doubly-fed wind power generator based on Matlab/Simulink simulation platform is established, and the simulation results with the parameters without any protective device of wind power system are compared. Experimental results show that the improved protection measures can effec- tively protect the wind turbines, which improves the ability of low voltage ride through. |
