摘要

为研究高肇（高坡—肇庆）直流融冰模式、正常模式的无功特性和谐波特性，基于EMTDC搭建了±500 kV高肇直流背靠背融冰详细模型并重点针对融冰模式、正常模式下换流站的无功特性和交直流侧谐波特性进行仿真研究。仿真结果表明:高坡站融冰模式的无功消耗比正常模式略大，肇庆站融冰模式的无功消耗则比正常模式略小;融冰模式下换流站交流谐波电流幅值比正常模式小、畸变率比正常模式大，而交流谐波电压及其畸变率均比正常模式小;融冰模式下同一换流站中两极处于不同的运行状态，两极直流侧谐波特性不相同。该研究结果为高肇直流在融冰方式下滤波器的投切提供一定的理论指导。

Abstract

To study the characteristics of reactive power and harmonic of Gao-Zhao high voltage direct current（HVDC） under deicing operation mode and normal operation mode， an EMTDC model of±500 kV Gao-Zhao HVDC with direct current power forth-and-reverse transmission deicing function is introduced in detail. With this model the characteristics of reactive power and harmonic at converter station are analyzed. Simulations show that:（1） Reactive power consumption at Gaopo converter station under deicing operation mode is larger than that under normal operation mode， while Zhaoqing converter station is on the contrary;（2） The amplitude of harmonic alternative current is smaller and total harmonic current distortion rate is larger compared to the normal operation mode， and the amplitude and harmonic distortion rate of alternative current voltage are both smaller than that of normal operation mode;（3） The two poles operating at different modes and the harmonic in direct system of each pole in the same converter station is different. Simulation results are helpful to the control of alternative current filter control under deicing operation mode.
