    • A control system (34) for controlling a multiphase power converter (12) includes a current control module (40), a voltage control module (100) and a current command selector (33). The current control module (40) generates grid voltage command signals for the multiphase power converter (12) and the voltage control module (100) generates reference converter current command signals for the current control module (40). The current command selector (33) supplies active and reactive current command signals from a supervisory controller (27) to the current control module (40) when the multiphase power converter (12) is connected to the grid and supplies the reference converter current command signals to the current control module (40) when the multiphase power converter (12) is unconnected to the grid.
    • 用于控制多相功率转换器(12)的控制系统(34)包括电流控制模块(40),电压控制模块(100)和电流命令选择器(33)。 电流控制模块(40)为多相功率变流器(12)产生电网电压指令信号,并且电压控制模块(100)为电流控制模块(40)产生参考变流器电流指令信号。 当多相电力转换器(12)连接到电网时,电流指令选择器(33)将来自监控控制器(27)的有功电流指令信号和无功电流指令信号提供给电流控制模块(40),并将参考转换器电流指令信号 当多相电力转换器(12)未连接到电网时,将电力供应到电流控制模块(40)。
