摘要
此处设计了一种三相四线制配电网静止无功补偿器(D-STATCOM),可准确地补偿电网的无功电流和零序电流。设计了D-STATCOM并联运行策略,可保证多台设备同时运行,均衡各台设备的输出电流。采用独立的DSP芯片完成系统的监控和保护功能,保证系统的稳定与可靠。单独设计无功电流补偿控制和零序电流补偿控制,控制方法更加灵活。仿真和样机测实验证了系统的有效性,具有一定的实用价值。
A distribution static synchronous compensator （D-STATCOM） of three-phase fou-line is designed, the D- STATCOM can accurately compensate the reactive and neutral current of power grid.Parallel operation strategy of D- STATCOM is designed to equalize the output currents of the compensators.To make sure that the muhiple devies operate steady, balance output current of each device.An additional DSP is used to execute the monitoring and protecting function.To ensure the system is stable and reliable.The reactive power compensation control and the neutral current compensation control are designed respectively,so the control system is more flexible.Simulation and prototype experiment verify the feasibility and practical value of the D-STATCOM.
