摘要: |
为了更便捷地进行MMC_UPFC的仿真建模,采用间接电流控制方案实现了UPFC串联侧换流器的简化、有效控制。基于MMC_UPFC系统的相量模型,详细推导了该控制策略的仿真建模方法。为提升仿真参数的真实性,参照国内某UPFC示范工程技术参数,在RTDS的小步长(ns级)模块中,设计了恒压移相控制、有功无功潮流控制及电网扰动下UPFC的动态响应等多个试验算例进行仿真。试验结果表明,该控制策略能够使MMC_UPFC系统快速、有效地跟随控制指令,并呈现良好的调压移相、潮流控制等调节性能。 |

Abstract: |
A simplified control method for the series side of MMC_UPFC is realized by adopting indirect current control scheme for building simulation model more conveniently. Based on the MMC_UPFC system’s phasor model, the process for modeling and simulation of the simplified control strategy is deduced. Some simulation tests are built on the RTDS’s microsecond-level module based on one demonstration project of UPFC such as constant voltage phase shift control, active and reactive power flow control, and UPFC dynamic response under power grid disturbance, etc. Simulation results show that the simplified control strategy can make the MMC_UPFC system follow the control instruction fast and effectively and present regulation performance like good voltage control and phase shift and power flow control, etc. |
