摘要
提出基于DSP的高压直流输电系统自适应触发角补偿控制方法。基于DSP设计出触发角转化系数,该系数能影响后续触发角,进而实现高压直流输电系统自适应触发角补偿控制,提高直流换相的裕度,防止换相失败的发生。所提出的方法经测试可有效减少高压直流输电系统后续换相故障的发生,具有可行性。
This paper proposes a DSP-based method of controlling adaptive trigger angle compensation for high-voltage direct current(HVDC)transmission systems.The work entails the design of a trigger angle conversion coefficient from DSP,which can affect the degree of impact of subsequent trigger angles,and the implementation of the proposed adaptive trigger angle compensation control for the HVDC transmission system,which can facilitate widening the margin of DC commutation and preventing commutation failure.The proposed control method has been verified effective in reducing the occurrence of subsequent commutation failures in HVDC transmission systems,and thereby practically feasible.
