摘　　要：采用数字仿真方法，通过离散傅里叶变换，分析了在ＴＣＳＣ稳态运行、工况调整过程及短路过程中ＴＣＳＣ线路电压、电流谐波的变化规律及波形畸变率的变化情况，着重分析了短路过程中触发角、短路时刻、短路地点、系统参数及短路后 ＴＣＳＣ是否旁路对ＴＣＳＣ线路波形畸变率的影响，主要结论是：在非故障状态下，电压、电流波形畸变率均在允许范围内；故障状态下畸变率增大，对系统电压质量和安全稳定运行带来影响。By using digital simulation method and discrete Fourier transform, this paper analyzes harmonics and harmonic distortion factor of TCSC line current and node voltage during the course of steady operation, regulating operation and short circuit operation respectively. The influence of firing angle, fault time. fault location. system parameters and TCSC's bypass on harmonic distortion factor in TCSC system are emphasized when a short circuit fault occurs. The relevant conclusions are drawn: during normal operation, the harmonic distortion factor is acceptable, but under fault condition. the harmonic distortion factor increases and has effect on voltage quality and security and stability of system operation.
