Embodiment Construction
[0022] The invention mainly solves the problem of power supply enterprises accurately judging whether large power customers or distribution transformers in station areas are out of power and the duration of power outages, so as to facilitate power supply reliability statistics and fault handling, and improve power customer satisfaction.
[0023] When a power outage or power-on event occurs on site, the on-site load control terminal or distribution transformer monitoring terminal will actively report the corresponding event. In view of various factors such as communication or on-site terminal failure, there may be false positives or missing reports in the power outage events reported by the on-site terminal. The technical solution adopted by the present invention to solve the technical problem mainly includes two parts. , to solve the situation of false reporting of power outage events, and the second is to solve the situation of false reporting through power outage event matchi...

The invention discloses a power failure event judging method based on an electric energy collecting terminal. The electric energy collecting terminal comprises an electric energy data read part, a display part and an electric energy data analysis part. The electric energy data analysis part determines a first reference node according to the positions of nodes of a power grid on-spot load control terminal, determines a second reference node according to the power failure information and assisting information of an initial circuit, and determines a third reference node according to the power failure information and assisting information of a bypass circuit; an optimized node is generated through the second reference node and the third reference node, and used for determining that the on-spot load control terminal can be used continuously when it is read that the on-spot load control terminal is located at a power failure event for the first time. By the power failure event judging method based on the electric energy collecting terminal, power supply reliability counting and failure processing can be carried out conveniently, and the satisfaction degree of power customers is increased.
Description
technical field [0001] The invention relates to a method for judging a power failure event based on an electric energy collection terminal. Background technique [0002] The power supply enterprise can accurately judge the power outage of the line through dispatching automation and other systems. For the power outage of a large power user or station area in the line, it is mainly judged by the power outage event reported by the power load control terminal and the distribution transformer monitoring terminal. However, due to battery problems, judgment standards, and stability problems in the load control and distribution transformer terminals, the reported events often have false positives, making it impossible to accurately judge whether there is a power outage. The present invention utilizes existing inaccurate event information, communicates with a terminal, performs reanalysis and judgment, and forms an accurate power failure event, so that it can be effectively used for ...
