在柔性直流换流器故障电流相位受控特性的影响下,传统距离保护在柔性直流交流送出线路发生单相经过渡电阻接地故障后易出现不正确动作行为。文中分析了柔性直流交流送出线路单相接地故障时的电气量分布规律,利用柔性直流交流送出线路单相接地故障期间换流站侧负序电流受抑制的新特征,提出一种基于综合序分量的新型单相接地距离保护。所提保护方案从理论上消除了过渡电阻的影响,可基于单端量准确计算故障位置。此外,该保护也适用于柔性直流并网于弱系统场景。最后,通过仿真验证了所提保护方案的有效性。
Under the influence of the phase-controlled characteristic of the fault current of the flexible DC converter
the traditional distance protection is prone to incorrect operation behavior after a single-phase grounding fault through a transition resistance occurs in the AC transmission line of flexible DC. This paper analyzes the distribution law of electrical quantities when a single-phase grounding fault occurs in the AC transmission line of flexible DC. Using the characteristic that the negative-sequence current on the converter station side is suppressed during the single-phase grounding fault of the AC transmission line of flexible DC
a new type of single-phase grounding distance protection based on comprehensive sequence components is proposed. The proposed protection scheme eliminates the influence of transition resistance theoretically and can accurately calculate the fault location based on single-end quantities. Moreover
this protection is also suitable for the scenario that flexible DC is integrated into a weak system. Finally
the effectiveness of the proposed protection scheme is verified through simulation
