| 摘 要： | 为了在1 000 kV特高压输电线路或有较大额定电流的750 kV输电线路上加装可控串补(thyristor controlledseries compensation,TCSC),解决目前TCSC中所需晶闸管阀通流能力不足的问题,提出了一种基于双阀控电抗器(thyristor controlled reactance,TCR)支路并联的TCSC实现方案,并对其控制策略进行了研究。通过对幅值相等控制策略下双TCR支路TCSC进行数学建模,设计了相应的阻抗控制环节和幅值相等控制环节,实现了相应的控制目标。仿真结果表明,提出的TCSC实现方案及其控制策略可行,适用于工程应用。 |

| Abstract: | The current capability of available thyristor valves of traditional thyristor controlled series capacitor(TCSC) is insufficient for 1 000 kV transmission line or 750 kV transmission line with relatively large current.Therefore a novel scheme based on two parallel thyristor controlled reactor(TCR) branches is proposed to deal with the current bottleneck.The mathematical model of this novel scheme is established and analyzed.The impedance control loop and the equal-amplitude control loop are designed in order to meet both the impedance and current sharing requirements at the same time.The simulation results show that the proposed TCSC and its control strategy are feasible. |
| Keywords: | thyristor controlled series capacitor(TCSC) thyristor controlled reactor(TCR) current sharing impedance control equal-amplitude control |
