One-key sequential control operation order non-power-cut visual checking method

Abstract

The invention discloses a one-key sequential control operation order non-power-off visual checking method, which comprises the following steps that a monitoring host can obtain the running state data of primary equipment and secondary equipment of a current time section, section data, namely simulation state data, is stored in a local database, and meanwhile, the monitoring host can realize bidirectional switching of a real-time state picture and an analog state picture, the real-time state picture reads real-time operation state data of the primary and secondary equipment, the analog state picture reads analog state data stored in a local database, isolation of the analog state data and pictures from the operation state data and pictures is realized, all the operations of the sequence control operation order simulation check by the monitoring host are carried out in the simulation database, the real-time database is not changed, the monitoring host can normally monitor the state of the equipment of the whole station, and the one-key sequence control operation order non-power-cut visual check is based on simulation state pictures and data. And the correctness of the sequential control operation order content is verified under the condition of ensuring that the power station end line is electrified.

Description

technical field [0001] The invention belongs to the field of factory station automation, and in particular relates to a one-button sequential control operation ticket visual verification method without power failure based on the factory station monitoring system. Background technique [0002] At present, in the field of power system station-side automation, the verification of the sequence control operation ticket by the monitoring host in the station-side monitoring system in the station mostly adopts the method of power failure verification, that is, according to the operation content of the sequence control ticket, stop the relevant Line, perform single-step power outage operation on the content of the operation ticket, and verify the correctness of the operation ticket. For newly-built plants and stations, the method of power outage verification sequence control operation ticket does not affect the off-line operation of the line. To verify the sequence control operation...

AI Technical Summary

Problems solved by technology

For newly-built plants and stations, the method of power outage verification sequence control operation ticket does not affect the off-line operation of the line. To verify the sequence control operation ticket, if it is necessary to re-verify the power outage line, it will bring a very heavy workload to the on-site operation and maintenance personnel, and it will take a long time. The operation and maintenance personnel are under great pressure and have heavy tasks
