摘要
在对统一潮流控制器（ＵＰＦＣ）的动态行为进行理论分析的基础上，利用电磁暂态仿真程序（ＥＭＴＤＣ）对ＵＰ－ＦＣ在稳态潮流调节时的动态过程进行了仿真，介绍了仿真模型及控制系统，给出了线路功率以不同频率波动及系统电压不对称时ＵＰＦＣ的动态响应曲线。结果表明，ＵＰＦＣ在潮流控制方面具有优良的特性，同时也发现，无论是稳态潮流调节时，还是在电力系统功率波动或系统电压不对称等电力系统不正常工作状态时，都有引起ＵＰＦＣ直流侧电压波动而危及装置安全的可能性。
Based on the theoretical analysis of the dynamic operation mechanism, the dynamic performance of UPFC(unified power flow controller) during power system power flow regulation and abnormal working conditions was simulated by using EMTDC program. A detailed model of UPFC and its control system were designed for EMTDC simulation. The dynamic response curves under line active power fluctuation and asymmetric system voltage were given. The simulation results proved that the UPFC was effective to regulate power flow. However, it was also showed by the simulation results that the DC voltage of UPFC is much higher than its nominal value if special control actions during the dynamic period were not taken.
