Problems solved by technology

However, under the condition that the continuously increasing high-power nonlinear loads in the power grid lead to increasing reactive power impact on the power grid, the existing method of using static var compensator to adjust the power grid voltage has a relatively small adjustment range for the power grid voltage. Small, unable to meet the reactive power compensation requirements of the power grid, resulting in uneven voltage distribution of the power grid, unable to meet the needs of safe and stable operation of the power grid

Abstract

The invention discloses a reactive compensation adjustment method, relates to the field of power grid operation technologies, and solves the technical problems that according to an existing method for adjusting voltage of a power grid by using a static reactive compensator, the adjustment range of the voltage of the power grid is relatively small, and the reactive compensation requirement of the power grid cannot be met, so that the voltage of the power grid is non-uniformly distributed, and the requirement of operating the power grid safely and stably cannot be met. The reactive compensation adjustment method comprises the steps of building a reactive optimization model for reactive compensation adjustment, and acquiring an optimal reactive compensation adjustment scheme; and performing reactive compensation on the power grid according to the optimal reactive compensation adjustment scheme. The method provided by the invention is applied to reactive compensation adjustment of the power grid.

Description

technical field [0001] The invention relates to the technical field of grid operation, in particular to a reactive power compensation adjustment method. Background technique [0002] In recent years, with the continuous increase of high-power nonlinear loads in the operation of the power grid, the reactive power impact and harmonic pollution of the power grid are on the rise. However, when the power grid operation mode changes, the lack of reactive power adjustment methods will make the power grid The voltage of the busbar changes greatly, which will lead to an increase in the line loss of the power grid and a decrease in the voltage qualification rate. [0003] At present, static var compensators (Static Var Compensators, SVCs) are often installed on load nodes in the power grid to increase or decrease reactive power supply according to the actual operation needs of the power grid and improve the voltage distribution of the power grid. However, under the condition that the...
