Embodiment Construction

[0037] The present invention will be described in detail below in conjunction with the drawings.

[0038] The AVC automatic control anti-misoperation locking function of the present invention mainly includes the following three functional transformations:

[0039] 1. Manual association of remote control points: Filter the alternative remote control point numbers on the modeling interface, and only display the remote control points connected to the current capacitor.

[0040] 2. Check the topology of capacitors and switches before control to confirm that the grid topology has not changed after the transmission test.

[0041] 3. Check the remote control point number, compare and check the stored remote control point, and confirm that there is no change in the remote control point number after the transmission test.

[0042] The configuration scheme of the present invention to transform the automatic voltage control module (AVC) of the D5000 system grid is as follows:

[0043] Intelligent c...

Abstract

A power grid AVC automatic control anti-misoperation locking method includes that an associated remote control point is automatically screened when an AVC system associates the remote control point for modeling; the AVC system performs automatic topology check on a capacitive reactor remote control point, a corresponding circuit breaker is found through the capacitive reactor according to the substation internal topology relationship before each remote control, whether a circuit breaker name and an ID associated with the circuit breaker are consistent during modeling with the AVC and conducting the topology check on a reactive device switch in a substation control unit; the AVC system automatically determines whether the remote control point number is consistent with the remote control point number during the transmission, issues a control command if the numbers are consistent and stops command issuing and given an alarm if the numbers are inconsistent. The AVC performs necessary verification to achieve intelligent security check on the AVC remote control point, ensures the correct remote control point, avoids false control and grid accidents, and ensures safe operation of a powergrid.

Description

Technical field [0001] The invention relates to an anti-misoperation locking method for AVC automatic control of power grid. Background technique [0002] The AVC function is an important part of the smart grid dispatching technical support system (hereinafter referred to as the D5000 system). From the convenience of user use and maintenance, the AVC application is required as a sub-application module of the D5000 system to realize embedded integration. The D5000 platform manages AVC related applications and processes through the system manager, and provides platform support for "AVC applications", including real-time libraries and related images. The main body of "AVC Application Module" is composed of AVC application process and AVC closed-loop control process, and is managed by D5000 system manager. The AVC closed-loop control process calls related sub-processes to complete the closed-loop control function according to control needs. [0003] With the continuous deepening of m...
