A relay protection debugging system and debugging method based on virtual trustworthy master station

Abstract

The invention provides a relay protection debugging system and debugging method based on a virtual relay protection and fault information master station. In the debugging system, a virtual MMS moduleis designed to send a MMS message with action information to replace the actual relay protection device action at a substation end, and the virtual relay protection and fault information master station is designed to replace the actual relay protection and fault information master station in the relay protection and fault information system; the virtual MMS module and the virtual relay protectionand fault information master station are connected with relay protection and fault information sub-stations in the relay protection and fault information system separately, and the relay protection and fault information sub-stations are tested with the virtual MMS module as the input incentive of the relay protection and fault information sub-stations, and with the virtual relay protection and fault information master station as the output of the relay protection and fault information sub-stations; and an automatic point countering platform is designed in the debugging system to check the input and output information of the relay protection and fault information sub-stations, so as to realize automatic debugging and improve the debugging efficiency and the debugging quality; meanwhile, allsemantic descriptions of different information sources are unified in debugging process, therefore, the ambiguity is avoided. The invention belongs to the field of intelligent substation.

Description

technical field [0001] The invention relates to a relay protection debugging system and a debugging method, belonging to the field of intelligent substations. Background technique [0002] With the development of smart grid, the accuracy of substation relay protection automation information has been paid more and more attention. Accurate debugging of substation relay protection automation is the premise of safe and stable operation of the power grid, which provides an important guarantee for improving the operation and maintenance level and operational reliability of the secondary system of the substation, and also creates necessary conditions for the safe operation and power supply reliability of the power grid . [0003] But at present, the debugging of substation relay protection automation still adopts manual methods, point-by-point debugging and manual proofreading. This situation has the following disadvantages: 1) The quality of commissioning varies from person to p...

[0003] However, at present, the debugging of substation relay protection automation still adopts manual methods, point-by-point debugging and manual proofreading

This situation has the following disadvantages: 1) The quality of commissioning varies from person to person, and human negligence is inevitable. The hidden dangers caused cannot be discovered in time, and losses have often been caused when hidden dangers are discovered; More and more, the workload of manual point detection is huge, which often affects the commissioning progress of substations; 3) Due to the difference between manual point recognition semantics and computer recognition semantics, such as "distance 2 segment" and "distance II segment" The difference will leave hidden dangers for the subsequent application of the data; 4) At present, the debugging of substation relay protection automation only detects the vertical consistency of the data, and does not test the horizontal consistency and standardization of the data description
