摘　　要：为了进一步提高电网管控精度,设计了一种基于改进矩阵算法的含DG电网管控方法。分析了FTU遥信信息在数据传输过程发生的畸变情况,设计了一种同步相量测试装置来获取电流相位参数并判断过电流的流动方向。研究构建了多个算例来验证上述方法对于信息畸变以及处理多重故障方面的可靠性。研究结果表明:去除电源后已经无法检测出过电流,依然能够判断故障发生的位置,采用本方法依然可以实现故障的准确定位。当电源侧区段出现故障并且末端节点出现数据传输畸变,通过信息修正能够实现准确定位。本文管控算法和畸变修正方法满足可靠性要求。该研究有助于提高电网运行效率,具有很好的实际节能意义。In order to further improve the precision of power grid management and control,an improved matrix algorithm based on DG network management and control method was designed.The distortion of FTU telemetry information during data transmission was analyzed,and a synchronous phasor measuring device was designed to obtain current phase parameters and judge the flow direction of overcurrent.Several examples were constructed to verify the reliability of the above method for information distortion and handling multiple faults.The results showed that the overcurrent could not be detected after the power supply was removed,and the fault location could still be determined,and the fault location could still be realized by using this method.When the power supply side section failed and the end node had data transmission distortion,accurate location could be realized through information correc‐tion.The control algorithm and distortion correction method in this paper met the reliability requirements.This re‐search is helpful to improve the operation efficiency of power grid and has good practical significance of energy saving.
