Abstract
Disclosed is a method for detecting a virtual secondary circuit of an intelligent substation. The method is characterized by comprising the following steps that A1, a detection module is connected to a network of a process layer; A2, the detection module analyzes an SCD file of the whole substation and conducts logic association; A3, setting of a pre-alarm condition is conducted on associated information; A4, real-time detection is conducted on the virtual secondary circuit; A5, the difference between a set value and an implemented value is judged through pre-alarm operation, and a handling suggestion is provided.
Description
Technical field
The present invention relates to a kind of intelligent substation virtual secondary circuit detection method, belong to intelligent substation technical field.
Background technology
Intelligent substation is built at IEC61850 communication protocol basis higher slice by intelligent primary equipment, networking secondary device, can realize the modernization transformer station of information sharing and interoperability between smart machine.Compared with conventional substation, the equipment of Intelligent transformer station wall and station level and network interface only interface and traffic model there occurs change, but process layer is connected by traditional electric current, voltage transformer, primary equipment and the cable between primary equipment with secondary device, change into the contents such as electronic mutual inductor, intelligent primary equipment, merge cells, Fiber connection.Intelligent Substation System is divided into 3 layers: process layer, wall, station level.Process layer comprises the smart machine, merge cells and the intelligent terminal that are made up of primary equipment and intelligent assembly, completes the correlation functions such as transformer station's power distribution, conversion, transmission and measurement, control, protection, metering, state-detection.According to the requirement of state's net Guidelines, specification, Direct Sampling is answered in protection, and the protection for monospace should directly be tripped, and the protection (bus protection) relating to multi-compartment should directly tripping operation.
The secondary circuit of intelligent substation is no longer the pure circuit structure formed with cable transmission single signal, but the network structure based on optical fiber and digital communication, each root optical fiber disalignment transmits multiple signals simultaneously, cannot again from outside direct physical connection go to analyze whole loop, be instead then virtual secondary circuit.How detecting secondary circuit, when breaking down in loop, how quick position fault point is the problem needing in intelligent substation process of construction to solve.
Summary of the invention
