Zusammenfassung:	Provided is a power distribution network reactive power planning optimization model considering fault risk and cost. The model enables the power distribution network line load to be divided into maximum, general and minimum three load levels; then, with reactive compensation capacity of each node being an optimization variable, a full life cycle cost model CLCC of reactive power compensation equipment is established under the condition of considering the influence of fault risk, and minimum of the CLCC is an objective function of a modified genetic algorithm; and installation capacity and switching gear of the reactive power compensation equipment are determined according to the obtained compensation capacity under the maximum load and minimum load operation mode. According to the model, the power distribution network reactive power planning optimization model considering fault risk and life cycle cost is established according to different load levels, and various cost of the reactive power compensation equipment in the full life cycle is taken into full consideration, so that the cost of the reactive power compensation equipment is saved, and effectiveness of power distribution network reactive power planning configuration is improved.
