Device and method for detecting secondary virtual loop of intelligent transformer substation

Abstract

Disclosed in the present invention are detection device and a detection method for a secondary virtual loop of a smart substation. The detection device includes: an input end of a configuration file reading module (10) connects with an output end of a background (13) of the smart substation; an input end of a configuration file parsing module (11) connects with an output end of the configuration file reading module (10); a digital signal generator (12) connects with a smart equipment acquisition card (20) and a smart operation box (30) respectively; the output end of the smart equipment acquisition card (20) connects with a merging unit (14) of the smart substation and an industrial switch (15) in turn; an output end of the smart operation box (30) connects with the industrial switch (15); an output end of the industrial switch (15) connects with an input end of an photoelectric converter (16); an output end of the photoelectric converter (16) connects with an input end of a virtual loop detection module (17). The technical solution can comprehensive detect connection performance of a secondary loop of the whole smart substation, guarantee accuracy of actions of a secondary equipment of the smart substation, provide technical base for accepting, transforming and improving an automatic system of the smart substation and a secondary equipment, and benefit safety production and stable operation of a power grid.

Description

technical field [0001] The invention relates to the detection field of an intelligent substation, in particular to a detection device and a detection method for a secondary virtual circuit of an intelligent substation. Background technique [0002] The electrical equipment of the power system is divided into primary equipment and secondary equipment. Primary equipment is the main body of the power system. It is the equipment that directly produces, transmits and distributes electric energy, including generators, power transformers, circuit breakers, disconnectors, power buses, power cables and transmission lines. Secondary equipment is equipment that controls, regulates, protects and monitors primary equipment, including measuring instruments, relays, operating switches, buttons, automatic control equipment, computers, signal equipment, control cables, and some power supply devices that provide energy for these equipment (such as batteries, silicon rectifiers, etc.). The s...

Problems solved by technology

[0005] The existing smart substation configuration is generated by each integrator based on the application background database of the IEC61850 protocol. However, at this stage, there is no general detection method for the secondary virtual circuit of the substation configured by the integrator, and the correctness of the secondary virtual circuit of the substation cannot be guaranteed.
