Problems solved by technology

However, SVG equipment can only compensate the reactive power in the local plant, and cannot obtain the model of the entire power grid. As a result, the equipment cannot consider the network loss and voltage level of the entire network during the adjustment process, which is very restrictive.

Abstract

The invention provides an automatic volume control (AVC) joint debugging method based on a static var generator (SVG). According to the automatic AVC joint debugging method based on the SVG, coordination control of the SVG in station and an existing discrete reactive compensation device is achieved by inserting the SVG in a converting station into an AVC system, adjustment times of a reactive device are reduced greatly, service life of the device is improved, and maintenance cost is reduced. Furthermore, the automatic AVC joint debugging method based on the SVG achieves continuous smooth adjustments of user side voltage and reactive power, reduces a voltage fluctuating range, improves power supply voltage stability, achieves continuous on-site compensation for the reactive power, reduces reactive mobility among factory stations, promotes electric transmission line power factors, and furthermore reduces system network losses.

Description

technical field [0001] The invention relates to an AVC joint debugging method, in particular to an AVC joint debugging method based on a static var generating device. The invention belongs to the field of automatic voltage and reactive power comprehensive optimization control of power grid. Background technique [0002] With the doubling of the power grid scale and the development of UHV transmission technology, power automation and smart grid technology have also been greatly improved. The traditional dispatching mode is highly dependent on the experience and level of dispatchers, which is not suitable for building strong and intelligent power grids. Grid development requirements. In this context, as an automatic voltage control system, AVC can realize the comprehensive optimal control of voltage and reactive power, improve the voltage stability of the power grid and greatly reduce the labor intensity of dispatchers. An integral part of the grid. [0003] Based on the re...
