摘要
描述了确定统一潮流装置(UPFC)参数的详细方法和步骤,按UPFC的功率模型确定了串联侧注入输电线路的电压幅值和相角、流过串联变换器的电流、并联侧变换器向系统注入的电流、串并联侧交换的有功功率、UPFC串联侧出口电压和并联侧接入母线电压的运行约束值。一套15kVA用于动模系统试验装置的基于EMTDC的仿真结果证明了在满足运行约束条件下,UPFC能快速有效的改善系统的电压和潮流。
The paper describes the method and steps for determining the parameters of unified power flow controller （UPFC）. Using the power model to determine the operating limits of UPFC, Which include： transmission line voltage magnitude and phase inserted by the series converter, the current going through the series converter, the current inserted by the shunts converter, the active power exchanging between the series and shunts converter, the line-side voltage of the series and the bus voltage of the shunts. When all of these limits are satisfied, the functions of UPFC can be brought to play completely. A test UPFC equipment used in dynamic analogy systems is designed. Simulation results using EMTDC demonstrate that UPFC can improve the voltage and power flow of the system rapidly and effectively when all the operating limit condtions are satisfied.
