Abstract

The invention discloses a power grid dispatching operation risk alarm and panoramic assessment method, which can solve the technical problem that the existing power grid dispatching operation risk alarm mode cannot effectively judge and derive the risk of a power grid. The power grid dispatching operation risk alarm and panoramic assessment method comprises: inputting power grid dispatching operation key information; judging the effectiveness of the power grid dispatching operation key information by adopting a data preprocessing method; processing the power grid dispatching operation effective information data by adopting a decision tree theory, dividing alarm information categories, and outputting alarm information; based on the output alarm information, establishing a power grid dispatching operation risk alarm panorama evaluation index system, and determining the weight of a power grid dispatching operation risk alarm panorama evaluation index; and assessing the power grid dispatching operation alarm panorama based on the radar map method and the output alarm information to obtain an assessment result of the power grid dispatching operation alarm panorama. According to the invention, a large amount of alarm information generated by the real-time alarm client can be effectively classified, so that the types of various alarm information are clearer, safer and more reliable.

Description

Technical field [0001] The invention relates to the field of electric power systems, in particular to a method for warning and panoramic assessment of power grid dispatching operation risks. Background technique [0002] With the continuous advancement of power grid construction, the scale of the dispatch automation system has expanded, the amount of access information has doubled, and the amount of alarm data generated by the system has also increased sharply. The existing automatic monitoring system alarm client will display these alarm information in a “swipe” manner according to the time sequence. Even if different alarm information has been classified through the message layering mechanism, different alarm pages will still be swiped by a large amount of information. In addition, the real-time alarm client still has the problem of rough message classification. At the same time, the existing automated monitoring system still lacks means to alert information that needs attenti...
