Control method for improving reliability of AVC (Automatic Voltage Control) system of electric power monitoring center

Abstract

The invention provides a control method for improving reliability of an AVC (Automatic Voltage Control) system of an electric power monitoring center. The control method comprises the steps of performing real-time telemetry data processing; performing real-time remote signaling data processing and dead data processing; and determining the data as dead data, locking a corresponding reactive voltage regulating device and sending alarm signals when the AVC system detects that telemetry information is not refreshed for a long time. The control method for improving the reliability of the AVC system of the electric power monitoring center has the advantages of achieving optimal control and closed loop operation of reactive voltage of the integral grid due to the fact that centralized monitoring, unified management and online control are performed on an on-load voltage regulating device and a reactive compensation device of every power substation in a power grid and ensuring that the AVC system enables a voltage reactive control strategy to be optimized, reducing the times of once action of the reactive voltage regulating device, improving the service life of the device and providing the corresponding technical support for improvement of the reactive voltage management level and safe, stable and high quality operation of the integral power grid due to the fact that the AVC system still relies on real-time data collected through an SCADA (Supervisory Control And Data Acquisition) system to calculate to a great extent.

Description

technical field [0001] The invention relates to a control method for improving the reliability of an AVC system in a power monitoring center. Background technique [0002] The automatic voltage control (AVC) system of Haiguang Temple Monitoring Center is based on the OPEN-3000 scheduling automation platform and is designed in an integrated manner. Through the SCADA system, the real-time data such as telemetry and remote signaling of each node in the whole network are collected for online analysis and calculation. On the premise of ensuring the safe operation of the power grid and reactive power equipment, the reactive power compensation equipment switching command or the main transformer sub head lifting command is issued. [0003] If the real-time data of the SCADA system is being transmitted, there is interference or there are human errors or errors during data maintenance, the reliability of the AVC system will be greatly reduced, and even wrong control instructions will ...
