Abstract

The invention discloses a district power network equipment abnormal alarm signal association analysis and diagnosis method in the field of automation of scheduling of electric power systems. According to the method disclosed by the invention, the weather situation of a plant station region at which abnormal alarm information is located can be automatically identified so as to determine the information processing mode. The method disclosed by the invention has the beneficial effects that by realizing intelligent association analysis and auxiliary decision making of the equipment abnormal alarm information under the real-time state, and performing playback on historical alarm information and performing real-time treatment on manual set information under the research state, the abnormal treatment time is greatly reduced, the incidence of accidents is reduced, a real-time, rich and intelligent auxiliary decision-making support is provided for regulation and control staff, and the safe, high-quality, economical and stable operation of an electric fence is further ensured.

Description

technical field [0001] The invention belongs to the field of electric power system scheduling automation, and in particular relates to a method for correlation analysis and diagnosis of abnormal alarm signals of regional power grid equipment. Background technique [0002] Equipment abnormal alarm signals mainly refer to some alarm signals issued in advance by the primary and secondary equipment of the power grid before the power grid fails, such as main transformer cooler failure, main transformer overload, circuit breaker SF6 low pressure alarm, protection alarm, grounding alarm, etc. . When this kind of alarm signal is sent to the dispatch center, it indicates that the power system is currently in a dangerous operating state, reminding dispatch operators to take timely measures to eliminate the hidden dangers that cause the alarm. At this time, there is no obvious abnormality in the operation of the power system, and the early warning signal is often mixed with In the nor...
