Problems solved by technology

[0003] The distribution network is an important part of the smart grid. With the increase of working hours and changes in environmental conditions, there will be risks of failures such as lightning strikes, icing, and external damage and various load losses, which have brought immeasurable impact on the national economy. In order to ensure the safe operation of the distribution network system, at present, the establishment of a reasonable distribution network status monitoring system is mainly used to promote the development of the transmission link. However, the existing distribution network management mode and maintenance system are difficult to achieve multi-parameter , All-round monitoring, low efficiency in judgment and maintenance of fault points, etc., will lead to the possibility of fault deterioration or even serious accidents, so it is necessary to design a set of systems that can better monitor the operation faults of the distribution network System solutions

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a multi-dimensional data-based power grid operation fault monitoring system. Background technique [0002] The power grid wide-area monitoring system adopts the synchronous phase angle measurement technology, and realizes the real-time high-speed collection of the synchronous phase angle of the entire network and the main data of the power grid through the gradual layout of the synchronous phase angle measurement unit (PMU) at the key measurement points of the entire network. The power dispatching data network is transmitted to the wide-area monitoring main station system in real time, so as to provide real-time monitoring, analysis and calculation of the normal operation of the power grid and accident disturbances, and to obtain and grasp the dynamic process of the power grid operation in a timely manner. As a dynamic measurement system for the power grid, WAMS Its pre-unit ...
