摘　　要：高压长距离输电线路最大输送功率远远小于线路的热稳定极限,造成大量电力资源浪费。为解决这一问题,对含有可控串联补偿装置的输电线路进行研究,通过分析可控串联补偿装置的结构、工作原理及其运行方式,设计了基于触发角校正的PID阻抗控制方式下的串联补偿装置,在PSCAD/EMTDC中搭建含可控串联补偿装置的输电线路模型,仿真结果表明:基于触发角校正的PID阻抗控制方式可以满足对触发延迟角的准确控制,体现出一定的鲁棒性。The maximum transmission power of high-voltage long-distance transmission lines is far less than the thermal stability limit of the lines,resulting in a large amount of power resource waste.In order to solve this problem,the transmission line containing controllable series compensation device is studied.By analyzing the structure,working principle and operation mode of the controllable series compensation device,a series compensation device based on PID impedance control mode based on trigger Angle correction is designed,and a transmission line model containing controllable series compensation device is built in PSCAD/EMTDC.The simulation results show that the PID impedance control method based on trigger Angle correction can meet the accurate control of trigger delay Angle,and embodies a certain robustness.
