Problems solved by technology

[0006] The purpose of the present invention is to provide a distributed voltage and reactive power optimization control method. This system overcomes the defects that local control cannot optimize the whole network and centralized optimization cannot achieve poor real-time performance. The basic idea is to make full use of existing station compensation Equipment (distributed voltage and reactive power control device VQC) and background optimization algorithm, on the basis of ensuring power quality, reducing network loss, and improving the operation and management level of distribution network, improve the optimization speed and reduce the transformation cost

Abstract

This invention relates to a distributed voltage quadrature optimization control method, which utilizes a voltage quadrature automatic control device ( VQC) popularly installed in transformer substations as the distributed control terminal and a voltage quadrature optimization software optimizes and computes networks to get a strategy for distribution network VQC to be sent to the VQC in the form of defined values of the voltage, quadrature upper and lower limit, which carries out automatic optimization selection and cast and cut control to the tap position of the transformer and the condenser set so as to guarantee the real time of the quadrature adjustment of voltages.

Description

technical field [0001] The invention belongs to the technical field of power system power quality control, and relates to a voltage and reactive power optimization control method of a regional power grid, in particular to a distributed real-time voltage and reactive power optimization control method. Background technique [0002] For more than 10 years, due to the rapid development of cities, the demand for electricity loads has been increasing, and the requirements for power quality and reliability of power supply have been improved. The existing power grid can no longer fully meet the requirements of various aspects. In recent years, with the deepening of reform and opening up, the rapid development of the tertiary industry, the continuous improvement of people's living standards, and the increase in summer peak load year after year, make the power grid face great pressure. If the transformation is not stepped up, it will not only affect the safe operation of the power gri...
