Power distribution network power quality disturbance positioning method with distributed power supply

The invention provides an electric energy quality disturbance positioning method for a power distribution network with a distributed power supply. The method comprises the following steps: arranging an electric energy quality monitor at a monitoring point of each line of the power distribution network; establishing a power distribution network power quality disturbance source positioning model; solving the power distribution network power quality disturbance source positioning model by using a matrix particle swarm positioning algorithm to obtain a disturbance source positioning position; according to the method, accurate positioning of the power quality disturbance source of the power distribution network is achieved, the fault tolerance rate and accuracy of positioning of the power quality disturbance source are improved, and the problems that an existing disturbance source positioning mode is large in error and low in accuracy rate are solved. 本发明提供一种带分布式电源的配电网电能质量扰动定位方法，包括以下步骤：在配电网各线路的监测点处设置电能质量监测仪；建立配电网电
