Abstract

The invention discloses an electrical transformer district low-voltage problem predicting method. The electrical transformer district low-voltage problem predicting method comprises collecting data; simplifying the electrical transformer district into a network formed by branch elements and a main element and estimating network parameters; determining the characteristic index of the user in each branch; predicting the maximum load of each branch year by year; calculating the voltage value and low voltage duration of each branch, carrying out statistics to the number of low voltage users; and judging the serious degree of the low voltage problem and completing the prediction. The invention also discloses a system for implementing the electrical transformer district low-voltage problem predicting method. The system comprises a data acquisition module, a data warehouse, a data processing module and an analyzing and warning module; the data acquisition module acquires data and stores the data to the data warehouse; the data processing module processes the data; and the analyzing and warning module analyzes, predicts and gives an alarm to the low-voltage problem of the electrical transformer district. By employing the electrical transformer district low-voltage problem predicting method and system, the number of low voltage users, the low voltage duration and the low voltage value are predicted, and the method is convenient, and the calculation is simple and accurate.

Description

technical field [0001] The invention belongs to the field of electric power system automation, and in particular relates to a method and system for predicting low voltage problems in station areas. Background technique [0002] The problem of low voltage is the core of the contradiction in the "last mile" problem of power supply services. The distribution transformer area is directly connected to the user and is a key node of power transmission. At present, the main areas where low-voltage problems occur are basically concentrated in the station area and the user end. Strengthening the prediction and management of low-voltage problems in the Taiwan area plays a decisive role in improving the quality of power supply, improving user experience, and enhancing the social responsibility of power supply companies. [0003] At present, domestic and foreign research on low-voltage problems and their control measures is mainly carried out from the following aspects: 1) Analysis of ...
