Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] like Figure 1 to Figure 4 As shown, it is a smart substation fault diagnosis and location method based on multi-factor comparison and visualization.

[0032] (1) The googleGIS service platform and the inspection and maintenance communication service platform are built. The two platforms are independent and coordinated with each other. The googleGIS service platform adopts the B / S architecture mode, and the SVG vector drawing uses ajax technology, JavaScript technology and html5 technology to dynamically and asynchronously visualize the entire power system; the inspection service communication service platform adopts the C / S architecture mode, and maintenance personnel can timely Respond to the instructions issued by the dispatch center of the master station;

[0033] (2) The relay protection equipment is encapsulated into a graphic element structure through t...

Abstract

The invention discloses an intelligent substation fault diagnosing and positioning method based on multi-factor comparison visualization. The method includes the steps of generating SVG graphic primitives of a relay protection device, indicating GoogleGIS geographic information, converting COMTRADE files into SVG files, comparing protection waveforms with definite value information, and positioning fault information. The dynamic visual behavior operation of the relay protection device is truly achieved; the healthy and stable running of a whole electric system can be globally and remotely monitored; through multi-factor comparison, the cause of faults can be more accurately and efficiently found; the fault location is indicated in time through a GoogleGIS; a main station dispatching center can completely visually monitor the running of the whole electric system in a responsibility area in real time; once a circuit and an electric device fail, the fault source location can be instantly positioned, and inspection and maintenance personnel near a fault source can be dispatched in time, and the real intelligent visual running maintenance of the whole electric system is achieved.

Description

technical field [0001] The invention relates to a fault diagnosis and positioning method for smart substations based on multi-factor comparison and visualization. It remotely monitors the fault information of smart substations through multi-factor comparison technology and GoogleGIS technology visualization, and can accurately locate the source of the fault. It belongs to the electric power industry. communication technology field. Background technique [0002] With the rapid development of society, the requirements for the stability and health of the smart grid are getting higher and higher. When a smart substation encounters a fault, it needs to respond immediately to quickly restore the normal operation of the grid. The current fault information system in the smart substation has realized the intelligent management of protection equipment, and its limitations are that the fault setting is relatively independent, only relying on relay protection management equipment, poor ...
