Abstract

The invention belongs to the technical field of distributed reactive power compensation, and particularly relates to a distributed reactive power compensation system and method, and the system comprises a plurality of power grid data collection modules disposed at a monitoring point, a plurality of reactive power compensation modules disposed at the monitoring point, and a plurality of distributed controllers and block chains disposed at the monitoring point. By means of decentralization of the block chain and trusted distributed shared database attributes, voltage and power factor data of the whole power grid can be conveniently collected for sharing, a compensation plan can be conveniently modified, a current control system structure with a group control center is changed, and data uploading and reactive power compensation plans are more convenient and faster. In addition, the current situation that only data collected by the current monitoring point is compensated at present is changed, compensation is carried out by sharing data collected by multiple monitoring points, and the compensation precision is higher.

Description

technical field [0001] The invention belongs to the technical field of distributed reactive power compensation, and in particular relates to a distributed reactive power compensation system and a compensation method. Background technique [0002] With the development of my country's industry, large-capacity and impact nonlinear loads such as rolling mills and electric arc furnaces in the iron and steel, metallurgy, and chemical industries have been connected to the power grid in large quantities, generating a large amount of harmonic currents and reactive power. It brings an extra burden and has a serious negative impact on the operation stability and dynamic performance of the power system. [0003] For the management of reactive power in the power grid, a reasonable solution should be to generate reactive power at the load that needs to consume reactive power, that is, local compensation of reactive power. The national power supply and consumption rules stipulate that reac...
