摘要
文中研究了可控串联补偿装置在关键线路潮流控制中的作用。通过建立用于分析可控串联补偿装置潮流作用的电路模型,列写功率方程,使用解析方法,画出功率运行范围、有功功率和无功功率变化曲线等;分析了单个可控串补对线路输送功率的作用,通过进一步解析,重点分析了UPFC+固定串补电容对线路输送功率作用;考虑到经济性后,对UPFC+固定串补电容方案进行了最优投资建模,并给出了求解流程。通过对江苏电网中关键线路的作用分析,明确了UPFC+固定串补电容方案的合理性,并验证了求解流程的有效性。
This paper studies the role of controllable series compensation device in the control of critical line powerflow.Through the establishment of the circuit model for the transmission line with controllable series compensationdevice,the power equations are developed;and the power operating range,active power and reactive power curve aredrawn by using analytical methods.Through further analysis,the effect of UPFC plus fixed series capacitor on thetransmission power is analyzed.After economic analysis,the optimal investment scheme of UPFC plus series capaci-tor solution is given.Through the analysis of the key lines in Jiangsu Power Grid,the rationality of the UPFC plus se-ries capacitor scheme is clarified and the validity of the solution procedure is verified.
