Automatic mapping monitoring system and method of intelligent substation secondary virtual loop

Abstract

The invention discloses an automatic mapping monitoring system and method of an intelligent substation secondary virtual loop. The method comprises the steps of: firstly, obtaining an SCD file for reading all station devices and carrying out analysis to obtain an included data models and connection relations corresponding to switches and virtual loop devices; creating pixels corresponding to different switches and virtual loop devices so as to form a pixel database; establishing a mapping correlation between the switch pixels and the switches, generating a switch network map indicating switch link connection relations, establishing a mapping correlation between the virtual loop device pixels and the devices, and generating a virtual terminal connection map indicating device link topological connection relations, with an interval serving as a unit; and finally, receiving real-time virtual loop link states uploaded by devices in the intelligent substation in real-time, updating the corresponding switch network map and virtual terminal connection map, and monitoring the link states online. According to the invention, the mapping efficiency of the switch connection map and the virtual terminal connection map can be improved, the online real-time monitoring level is increased, and the operation and maintenance efficiency of the secondary virtual loop is improved effectively.

Description

Technical field [0001] The invention relates to an automatic graphing monitoring system for a secondary virtual circuit of an intelligent substation, and also relates to an automatic graphing and monitoring method for a secondary virtual circuit of an intelligent substation, belonging to the technical field of power system automation. Background technique [0002] The voltage, current, switch value, control and other signals in the secondary circuit of the traditional substation relay protection device are connected by cables, and the secondary circuit is clear and visible. For example, in a traditional substation, various secondary devices are connected by cables, and the input and output ports of the devices are called input terminals and output terminals, respectively. The output terminal of the A device and the input terminal of the B device are connected by a cable to form a secondary circuit. The electrical signal on the secondary circuit has a DC signal and an AC signal. ...
