Abstract

The invention discloses a power distribution network reactive power optimization system and method based on multi-data analysis. The system comprises: a distribution network data acquisition device for acquiring 10kV line outlet node real-time data and transmitting the same to a host computer control system; a dynamic reactive power compensation device for uploading distribution network operating data and reactive power compensation device running status data to the host computer control system by using GPRS. The method, through the EMS and distribution network automation system, get access to the data of each node of a 10kV line, carries on the load flow calculation, obtains the distribution of the voltage, active power and reactive power of each node of the line, and makes the line run in an optimal state through reactive power strategy control, develop reactive power optimization strategy through a genetic algorithm to determine the compensation point, compensation capacity and the like, controls the reactive power compensation equipment in the distribution network to achieve full distribution network reactive power optimization operation control.

Description

technical field [0001] The invention relates to the technical field of reactive power compensation, in particular to a reactive power optimization system and method for a distribution network based on multi-data analysis. Background technique [0002] With the separation of power generation from transmission and distribution and the implementation of new power market reforms, the requirements for the optimal dispatching function of the entire distribution network as a whole are becoming more and more stringent, and the requirements for real-time compensation capabilities are also increasing, which affects the power supply quality of the entire system And economic interests, but also related to the safe and normal operation of the power grid. At present, most of the power grid systems in operation in my country belong to the situation of excessive active power supply and insufficient reactive power supply. Reactive power optimization can reduce network loss, resource consumpt...
