Merging method for remote signaling information of remote-action system of transformer substation

Abstract

The invention relates to a merging method for the remote signaling information of a remote-action system of a transformer substation, and the method comprises the steps: creating a merged signal management unit which is used for storing a merged signal point after the logic calculation; setting a branch signal configuration table, and setting a group number; binding a signal merging logic calculation rule, searching the group number configuration information of each branch signal in the configuration table, and completing the grouping of the branch signals; performing the driving of the mergedsignal in two modes: state drive and item drive, wherein the timing scanning state is performed for calculation in the state drive mode, and the real-time reading of SOE is performed for calculationin the item drive. The method meets that a scheduling main station system performs the comprehensive monitoring of the operation conditions of a transformer substation device, improves the signal merging processing flexibility, solves a problem that a single branch signal cannot participate in the logic calculation of a plurality of merged signals, achieves the correlation between the merged signal and the branch signal participating in the logic calculation, achieves the signal recursion, and meets the different logic demands of signal merging.

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
