Problems solved by technology

[0004] However, in the process of actual operation, after the adjustment of the automatic voltage control system, there is an adjustment error between the actual voltage value and the voltage target value. The existence of the adjustment error leads to a low pass rate, which in turn affects the stability of the power system voltage.

Abstract

The invention provides an electric power system voltage regulation analysis method and device based on operation data. The method comprises the steps of acquiring multiple target time points meeting preset judgment conditions in all time points of an electric power system; determining a plurality of target time periods based on the plurality of target time points, and extracting reactive operationdata corresponding to each target time period; classifying the reactive operation data corresponding to each target time period; and determining influence factors corresponding to the classificationsand determining adjustment modes of automatic voltage control systems corresponding to the influence factors. According to the invention, the voltage qualification rate of the power system can be improved, and the voltage stability and the wind power absorption capability of the power system are further improved.

Description

Technical field [0001] The present invention relates to the technical field of power systems, in particular to a method and device for power system voltage adjustment analysis based on operating data. Background technique [0002] Voltage stability refers to the ability of the system to maintain voltage. When the load admittance increases, the load power also increases, and the power and voltage are both controllable. Voltage stability is one of the many problems that traditional power systems have to face. With the integration of large-scale wind farms into the power grid, the problem of voltage stability faced by the power system has become increasingly serious. In order to solve the voltage stability problem caused by the grid connection of wind power, the power grid dispatching agency is equipped with an automatic voltage control (AVC) system master station, and each wind farm is equipped with an automatic voltage control system substation. [0003] When the two conditions a...
