Embodiment Construction

[0041] Below, the technical solution of the present invention will be further described in detail according to the accompanying drawings.

[0042] Such as figure 1 Shown is a schematic diagram of the structure of the intelligent program-controlled anti-misoperation locking system of the present invention.

[0043] Integrated design of intelligent program-controlled anti-misoperation locking system, including the following components:

[0044] ●Monitoring system background computer. The background computer of the monitoring system realizes the monitoring and control functions of the original monitoring system. In addition, it integrates the functions of the five defenses and the operation ticket system, and realizes the function of issuing program-controlled anti-mistake commands.

[0045] ●Monitoring system network. The monitoring system network realizes the monitoring and control data transmission function of the original monitoring system, and also realizes the function o...

Abstract

The invention discloses an intelligent program-control error-locking prevention system based on integrated design. An anti-misoperation host and a monitoring background host are integrated, and a measurement-control network and an anti-misoperation network are integrated. A measurement-control unit is provided with a five-prevention locking node which can be controlled in a monitoring system background, and the five-prevention locking node is a normally opened node in series with an operation circuit, so operation can be performed only when the five-prevention locking node is closed, regardless of remote control or on-site operation. After the five-prevention logic of inspection equipment completes the simulated preview of operation tickets on a monitoring-system background host, according to a formed sequence of the operation tickets, a background monitoring system automatically closes the five-prevention locking node corresponding to current equipment to be operated, and the closure of the mode shows that the equipment passes double verification about five-prevention logic locking and operation-ticket sequential locking. The error-locking prevention system can ensure that only the correct equipment can be operated within the whole range of a substation, regardless of remote control through the host in a station control layer, operation in an interval layer or on-site operation in an equipment layer.

Description

technical field [0001] The invention belongs to the technical field of power system automation, and in particular relates to an intelligent anti-misoperation locking system of a substation. Background technique [0002] Misoperation of the power system will cause casualties and damage to power equipment, and even lead to serious consequences of large-scale power outages. Therefore, my country's power system has promulgated the "five prevention" rules and requirements for preventing five types of vicious misoperation accidents in power systems. [0003] At present, the microcomputer anti-misoperation locking system required by the "five preventions" rules is mainly divided into two types, namely, the off-line microcomputer anti-misoperation locking system and the online microcomputer anti-misoperation locking system. [0004] (1) Offline microcomputer anti-misoperation locking system: [0005] The off-line microcomputer anti-misoperation locking system is currently the most...
