换相失败恢复策略中的低压限流环节参数大多选择折中值或经验值
没有充分考虑无功功率的动态需求
影响系统恢复中的控制性能.文章建立了电流指令值与交流母线电压的关系式
提出了基于交流母线电压求解电流指令的恢复策略
采用静止同步补偿器(STATCOM)解决因恢复速率过快导致再次换相失败的问题
改善系统恢复特性.通过搭建仿真模型验证恢复策略可以改善系统的恢复特性
有效避免后续换相失败等问题.
Most of the parameters of the VDCOL in the commutation failure recovery strategy are chosen to be the compromise value or the empirical value
dynamic demand for reactive power is not fully considered
affect control performance in system recovery. The relationship between the current command value and the AC bus voltage is established by derivation
a recovery strategy based on AC bus voltage for current command is proposed
the STATCOM is used to solve the problem that the recommutation fails due to the fast recovery rate
improve system recovery characteristics. The simulation model is built to simulate the effectiveness of the verification recovery strategy in improving the recovery characteristics of the system and avoiding subsequent commutation failures.
