为提高永磁直驱风电并网系统低电压穿越能力，提出采用串联制动电阻SDBR（series dynamic braking resistors）和超级电容储能系统SCESS（supercapacitor energy storage system）协调控制方法。当电网电压跌落时，串联在并网点与电网之间的SDBR消耗一部分不平衡能量同时抬升并网点电压，剩余的不平衡能量由并联在直流链的SCESS吸收。利用MATLAB/Simulink软件进行仿真，结果表明SDBR-SCESS协调控制策略在故障期间能够有效抑制直流链电压峰值以及抬升并网点电压，降低故障切除瞬间的并网电流峰值，在故障切除后有效缩短直流链电压及并网电流的恢复时间，提高永磁直驱风电低电压穿越能力；与单独使用SDBR或SCESS相比，SDBR-SCESS协调控制具有更优越的效果。

Abstract

收起

To improve the low voltage ride-through capability of a permanent magnet synchronous generator (PMSG) grid-connected wind power system, a coordinated control method based on series dynamic braking resistors (SDBR) and a supercapacitor energy storage system (SCESS) is proposed. When the grid voltage drops, the SDBR connected in series across the grid will consume part of the unbalanced energy while raising the voltage at the grid-connected point, and the remaining unbalanced energy will be absorbed by the SCESS connected in parallel to the DC chain. Simulation results based on MATLAB/SIMULINK show that the SDBR-SCESS coordinated control strategy can effectively suppress the peak DC chain voltage and raise the voltage at the grid-connected point under fault, reduce the peak grid-connected current at the moment of fault removal, effectively shorten the recovery time of DC chain voltage and grid-connected current after fault removal, and improve the low voltage ride-through capability of the PMSG. Compared with the control based on SDBR or SCESS alone, the SDBR-SCESS coordinated control has a superior effect.
