A Method of Locating Voltage Disturbance Sources Based on FP-Growth Algorithm
Positioning disturbance sources is the prerequisite of defining the power quality pollution liability and improving the management of power system.This paper presents a method to analyze the mutual influence of the voltage events generated from the different nodes and then locate the voltage disturbance sources in a grid based on massive existing power quality monitoring data and association rule algorithm.Technically,a batch of actual power quality data from a single-node sequential list was transformed into a multi-node parallel two-dimensional table.Then the PFgrowth algorithm was adopted together with some appropriate parameters to calculate the affecting relationship on voltage events between the nodes.Compared with the traditional system simulation and matrix calculation methods,this method is superior in low cost,fast and efficient computing features.
