摘　　要：针对长距离、重负荷线路末端电压偏低的问题,提出了串联电容补偿调压技术。可控串联补偿调压技术(TCSC)由于其可连续调节串补容抗,实现对负荷侧电压的连续调节特征,正逐步取代固定串联补偿技术,成为主要的串补调压技术。本文分析了可控串联补偿调压的原理和相关参量的计算,重点对TCSC调压系统的调压性能进行分析,研究负荷负载率、负荷功率因数和晶闸管触发角对TCSC系统调压性能的影响,为TCSC调压技术的应用提供理论依据。Aiming at the problem of low voltage at the end of long distance and heavy load lines,a series capacitor compensation voltage regulation technology is proposed.The controllable series compensation voltage regulation technology(TCSC)is a continuous series-compensated voltage regulation technology because it has the ability to continuously adjust the series compensation capacitance to achieve continuous adjustment of the load side voltage.This paper analyzes the principle of controllable series compensation voltage regulation and the calculation of related parameters,and focuses on the analysis of the voltage regulation performance of TCSC voltage regulation system.The effects of load load factor,load power factor and thyristor firing angle on the voltage regulation performance of TCSC system are studied.It provides a theoretical basis for the application of TCSC voltage regulation technology.
