Problems solved by technology

[0003] Most of the optimization objects of reactive power optimization are concentrated in the main power transmission network, and have not been extended to the distribution network. The characteristics of the distribution network are more complicated, and more means are needed to participate in it. At present, there is no optimization scheme that can be adopted.

Abstract

The invention discloses a reactive optimization method for a distribution network. The method comprises the following steps: firstly, building an actual operation model of the distribution network, then conducting load flow calculation, analyzing the voltage quality, applying a reactive optimization administrative tool to formulate a reactive optimization scheme, adopting the simulated analysis method to examine and regulate the appointed optimization scheme, and finally achieving reactive optimization of the distribution network according to the regulated reactive optimization scheme. The invention also discloses a reactive voltage optimization system for the distribution network, which corresponds to the method. The method and the system solve the difficult reactive optimization problem of the distribution network and provide theoretical foundation and decision support for planning, operation, reconstruction and management of the whole distribution network.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a reactive power optimization method and system for a distribution network. Background technique [0002] With the rapid development of the national economy and the improvement of people's living standards, people's demand for electricity is increasing, and at the same time, higher requirements are put forward for the reliability and quality of power supply. Due to the continuous increase of power grid load, not only the network structure and power supply distribution of the power system have been changed, but also the reactive power distribution of the system is not reasonable, and there may even be serious shortage of reactive power in some areas and generally low voltage levels. Whether the reactive power distribution of the power system is reasonable or not is not only related to the quality of power provided by the power system to users, but also directly affects the s...
