The invention relates to a monitoring method, device and system for a distribution network station area. Among them, the distribution network station area monitoring method obtains and records the power data periodically collected by the distribution transformer monitoring and metering terminal; the power data includes the three-phase voltage and / or three-phase current of the distribution network station area; when the power data meets the preset fault feedback When the rules are specified, the corresponding fault information is transmitted to the external terminal. Solve the problems of incomplete analysis of abnormal information, unsatisfactory monitoring effect and low intelligence in the traditional station area monitoring system; it can actively analyze the fault information and send it to the external terminal to notify the grid operation and maintenance when the distribution network station area is running abnormally In order to take effective measures to maintain the power grid in a timely manner, achieve rapid response and quick power restoration, and reduce power outage time for users in the station area.
Description
technical field [0001] The invention relates to the technical field of power grids, in particular to a monitoring method, device and system for a distribution network station area. Background technique [0002] At present, the functions of distribution transformer monitoring and metering terminal (TTU, Transformer Terminal Unit) are becoming more and more abundant, which provides great convenience for power grid enterprises to monitor the operation status of distribution transformers and the load status of the station area. [0003] During the implementation process, the inventors found that there are at least the following problems in the traditional technology: when the station area is operating abnormally, the distribution transformer monitoring and metering terminal only uploads the data to the background system, and there is a large delay in the feedback of the abnormal situation, and it cannot be restored to normal in time powered by.
