Disturbance positioning method combining multi-observation compressed sensing and entropy weight method

The invention discloses a multi-observation compressed sensing and entropy weight method combined disturbance positioning method, and belongs to the technical field of power systems. The invention aims to provide a multi-observation compressed sensing and entropy weight method combined disturbance positioning method which utilizes a compressed sensing technology, takes branch positive sequence current, branch active power, branch positive sequence voltage and the like as observation quantities, and combines the entropy weight method to calculate the weight of the relative disturbance degree of the three observation quantities before and after disturbance. According to the method, three different electrical quantities are selected as observed quantities in a compressed sensing algorithm, and weights of relative disturbance degrees of different observed quantities are calculated in combination with an entropy weight method; then a disturbance over-complete dictionary is designed in advance according to topologi
