Intelligent substation avalanche test method and system based on SCD file and terminal equipment

Abstract

The invention relates to an intelligent substation avalanche test method and system based on an SCD file and terminal equipment. The testing method comprises the following steps: analyzing remote signaling signals and remote measuring signals from an SCD file of an intelligent substation; then, carrying out setting processing on the remote signaling signals, carrying out telemetering setting processing on the remote measuring signals, and then sending a certain number of remote signaling displacement signals and / or remote measuring signals to the transformer substation to detect whether a monitoring system correctly receives a first preset number of avalanche remote signaling displacement signals and whether the monitoring system operates normally or not. Based on the SCD file of the intelligent substation, remote signaling and remote measuring signals of the SCD file can be analyzed for completing remote signaling and remote measuring avalanche tests. A large amount of remote signaling displacement is simulated through a remote signaling signal setting mode analyzed in an SCD file, and remote signaling avalanche is achieved; through a mode of simultaneously setting SCD file remotemeasuring signals, a large amount of remote measuring out-of-limit is simulated, and remote measuring avalanche is realized.

Description

technical field [0001] The invention relates to an avalanche test method, system and terminal equipment of an intelligent substation based on an SCD file. Background technique [0002] The SCD file is the abbreviation of the substation configuration description in the IEC-61850 standard of the substation, that is, the overall station system configuration file. The file contains the remote signaling and telemetry signals of the IED equipment (intelligent devices, such as measurement and control devices, protection devices, etc.) of the substation bay layer. [0003] According to the network data flow of the substation dispatching automation system, the operation status of the substation can be divided into: normal state, emergency state and critical state. [0004] The avalanche simulation is the critical state of the substation. At this time, the substation receives a large amount of data including line tripping, far-cutting, voltage collapse, and frequency drop in a short p...
