A Fault Detection Method for Power Grid Lines Based on RPA Technology
Due to the power grid fault detection has the characteristics of repeatability,high accuracy and low value,there exists low efficiency of manual detection of line fault data.Therefore,RPA thinking is used to design the fault data detection method of power grid lines.The three-stage RPA repeated judgment method is introduced into the fault judgment process.The fault area is determined by calculating the time when the initial traveling wave head reaches the fault endpoint which is constructed by the detection matrix and the time matrix.A suspected fault line is found in the fault area,and combining with a defined virtual bus,the exact fault line is determined through repeated calculation and verification.The experimental results show that the ab-solute error of fault detection using the proposed method is small,the error detection rate and the missing fault detection rate are lower,the recall rate and precision rate of fault data detection are higher,and the practical application effect is good.
