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

Abstract

The invention discloses a device for detecting a secondary virtual loop of an intelligent transformer substation. The input end of a configuration file reading module is connected with the output end of a background of the intelligent transformer substation; the input end of a configuration file analysis module is connected with the output end of the configuration file reading module; a digital signal generator is respectively connected with an intelligent equipment acquisition card and an intelligent operating box; the output end of the intelligent equipment acquisition card is sequentially connected with an intelligent transformer substation combination unit and an industrial switch; the output end of the intelligent operating box is connected with the industrial switch; the output end of the industrial switch is connected with the input end of a photoelectric converter; and the output end of the photoelectric converter is connected with the input end of a virtual loop detection module. The invention also provides a method for detecting the secondary virtual loop of the intelligent transformer substation. The invention has the advantages that the secondary loop connection performance of the whole transformer substation can be comprehensively detected, the motion accuracy of the secondary equipment of the transformer substation is ensured, technical basis is provided for checking, reforming and improvement of a transformer substation automatic system and the secondary equipment, and the safety production and steady operation of a power grid are facilitated.

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.
