A sequential control system and method

Abstract

The invention provides a sequence control system and method. The system comprises a monitoring server, a sequence control operation inspection device and an anti-error host, wherein the sequence control operation inspection device is used for receiving a sequence control operation instruction sent by the monitoring server; the sequence control operation instruction contains at least one piece of single-step execution operation ticket information; the sequence control operation inspection device decomposes the sequence control operation instruction into several pieces of single-step execution operation ticket information; the anti-error host is used to receive the operation ticket information sent by the sequence control operation inspection device, carry out logic inspection operation on each piece of operation ticket information and feed back a logic inspection result to the sequence control operation inspection device; and the sequence control operation inspection device receives thelogic inspection result and then sends to the monitoring server, and the monitoring server sends the sequence control operation instruction to controlled equipment. The method is realized through applying the sequence control system. In the invention, under the condition that an existing anti-error system is not changed, sequence control operation is realized, and there is less impact on a transformer substation and other places that need to be reconstructed.

Description

technical field [0001] The invention relates to the field of anti-misoperation of electric power systems, in particular to a system for realizing sequence control and a method for realizing sequence control by applying the system. Background technique [0002] my country's power system includes a power generation system and a power supply system. The power generation system mainly uses power stations to generate electricity, using coal, water energy, wind energy and other energy sources to generate electricity. The power supply system transmits the electric energy output by the power generation system to users. Distribution networks such as transmission lines. [0003] Taking the power distribution cabinet of the distribution network as an example, the current power distribution network usually has various power distribution cabinets, and various switches are installed in the power distribution cabinet. Power off, and after the power supply lines and switches are powered off...

Problems solved by technology

[0010] However, no matter which method is used to realize the sequential control operation, it is necessary to transform the original monitoring system of the substation, such as the transformation of the substation automation system, the integrated control system, and the centralized control system of the substation. The transformation of the microcomputer-based anti-misoperation and electrical misoperation operating system requires a lot of work and many systems need to be transformed, so it has a great impact on the operation of the substation. Not only does it take a lot of time and money to transform, Moreover, during the transformation period, it may also affect the original monitoring system of the substation, and even affect the safe operation of the substation.
