摘要

在常规直流输电系统中

频率控制器配置在整流侧

在站间通信中断时

逆变侧的频率无法送至整流侧

因而无法实现对逆变侧的频率控制。为此

提出了一种站间通信中断时的逆变侧频率控制方法

及一种适应该方法的直流系统启动策略和站间通信中断与恢复时定电流与定电压控制器的自动切换策略。应用该策略的实时数字仿真系统(RTDS)试验结果表明

所提策略兼具实用性和可实施性

对实现无站间通信下的高压直流输电系统逆变侧频率控制具有一定的参考价值。

Abstract

In conventional high voltage direct current (HVDC) power transmission system

frequency controller is configured on the rectifier side. The inverter frequency control can’t be realized when telecommunication is interrupted between stations due to no signals of its inverter to be sent to the rectifier. An inverter-side frequency control method is proposed

which is suit for a DC system startup strategy and an automatic switching strategy between constant current control and constant voltage control when the telecommunication status is instable. In the end

the practicability and reasonability of the proposed strategy are verified by the real time digital system (RTDS) simulation results. The strategy provide a good reference for inverter-side frequency control without telecommunication between stations.
