Power grid multi-source information-based fault integrated analysis system and analysis method

Abstract

The invention relates to a power grid multi-source information-based fault integrated analysis system and an analysis method. The fault integrated analysis system comprises four parts, namely an acquisition module, a data storage module, a fault analysis module and a fault display module. The acquisition module is respectively connected with a fault wave-recording master station, an information protection master station, a DMS / SCADA system and a WAMS master station. The data storage module and the acquisition module are connected. The fault analysis module and the data storage module are connected. The fault display module and the fault analysis module are connected. According to the technical scheme of the invention, the problems of inaccurate fault analysis and wrong judgment on protection actions due to insufficient information sources and inconsistent analysis policies during the fault information analyzing process of the information protection master station and the fault wave-recording master station can be well solved. Meanwhile, the system and the method are obvious in effect. The analysis level of power grid faults is enhanced, and the potential of an existing fault analysis system is fully developed. Multi-source fault information data can be better coordinated.

Description

technical field [0001] The invention belongs to the technical field of grid fault monitoring, and relates to a fault comprehensive analysis system and analysis method based on grid multi-source information. Background technique [0002] With the continuous growth of the receiving end load and the continuous expansion of the scale of cross-regional networking, coupled with the influence of the market-oriented reform of the electric power industry and the constraints of the ecological environment, the grid structure and grid operation mode are becoming more and more complex, and the unstable factors of the system operation continue to increase. The risk of large-scale outages triggered by faults is also rising. In addition, with the development of social economy, the advancement of science and technology and the improvement of people's living standards, people's demand and dependence on electricity are increasing, and the demand for safe and high-quality power supply is becomi...

AI Technical Summary

Problems solved by technology

[0006] The present invention aims to overcome the fact that the existing various power grid fault diagnosis and analysis systems operate independently and lack coordination mechanisms, resulting in unavoidable one-sidedness in the process of locating, analyzing and processing power grid faults, and also resulting in complicated and bloated post-accident analysis reports Defects, providing a comprehensive fault analysis system and analysis method based on multi-source information of the power grid, the present invention strengthens the level of fault analysis of the power grid, fully taps the potential of the existing fault analysis system, and better coordinates the processing of multi-source fault information data
