A method for merging remote signaling information of substation telecontrol system

Abstract

The invention relates to a method for merging remote signaling information of a substation telecontrol system. A merging signal management unit is created to store the merging signal points after logic operations; a sub-signal configuration table is set, and group numbers are set; binding signals Merge the logic operation rules, search the group number configuration information of each sub-signal in the configuration table, and complete the grouping of the sub-signals; the drive of the merged signal includes two modes: state-driven and event-driven, state-driven timing scan state for calculation, and event-driven Read SOE in real time for calculation. The invention satisfies the comprehensive monitoring requirements of the dispatching master station system for the operation of substation equipment, improves the flexibility of signal combination processing, solves the problem that a single sub-signal cannot participate in the logic operation of multiple combined signals; and realizes the combined signal and The association between the sub-signals involved in the combined calculation realizes the signal recursive operation and meets the different logic requirements for signal combination.

Description

technical field [0001] The invention belongs to the technical field of electric power system substation automation system, and in particular relates to a method for combining remote signaling information of a substation telecontrol system. Background technique [0002] The telecontrol system is an important part of the substation automation system, and plays a connecting role in the entire substation automation system. The basic function of the substation telecontrol system is to realize the collection, storage, processing and forwarding of information in the substation to the dispatching master station. The dispatching master station can intuitively grasp the operation status of the equipment in the substation through the information sent by the telecontrol system. Therefore, the telecontrol system The timeliness and accuracy of information, especially remote signaling information, is the key to improving the automation level of substations; at the same time, under the prem...

AI Technical Summary

Problems solved by technology

[0003] In the current substation automation system, there are many types of equipment, and most of the newly built and renovated stations are in the unattended mode. To realize the comprehensive monitoring of the situation in the station by the dispatching master station system, it is necessary to send a large amount of remote signaling information to the telecontrol system. Too much information will cause problems such as low transmission efficiency, heavy load, and inconvenient monitoring
