【摘要】 为了将统一潮流控制器UPFC(unified power flow controlle)r嵌入到商业软件中,采用节点注入电流法建立了UPFC的潮流控制模型。该模型通过控制UPFC串联侧节点的注入电流和并联侧节点的无功注入电流来控制线路潮流和UPFC接入点母线电压,其中,串联侧节点的注入电流通过功率目标方程直接求取,并联侧节点的无功注入电流通过引入被控母线电压的参考值与实际值的偏差求得。基于电力系统分析综合程序PSASP(power system analysis software package)进行了算例研究,结果表明所建模型能有效实现UPFC的潮流控制作用,且具有较快的潮流追踪速度和较高的收敛精度。对其他FACTS(flexible AC transmission system)器件的控制建模具有一定的参考价值。更多还原

【Abstract】 In order to insert unified power flow controller(UPFC)into commercial software,a new power flow control model based on current-injected method was proposed.In this model,the power flow of transmission line and bus voltage were controlled by the injected current of the series side node and the reactive injection current of the parallel side node,respectively.The former was calculated through the power target equation,and the latter was obtained by calculating the deviation between reference voltage and actual bus voltage.Case study was done based on power system analysis software package(PSASP),and result shows that the proposed model can effectively control the power flow with fast rate of tracking the control goal and high convergence precision,and it is instructive for modeling of other flexible AC transmission system(FACTS)controllers.更多还原
