Method for realizing distribution network load automation acquisition and displaying by using load control terminal

Abstract

A method for automatically collecting and displaying distribution network loads by using a load control terminal, comprising the following steps: 1) The distribution network master station system sends a call message containing the information of the metering points concerned to the metering automation front-end system, and the metering According to the metering point information recorded in the calling message, the automatic front-end system forwards the calling message to the corresponding metering terminal; 2) after receiving the calling message, the metering terminal sends a response message containing telemetry data to The metering automation front-end system is then sent to the distribution network master station system by the metering automation front-end system; 3) The distribution network master station system receives the response message and outputs it to the user terminal for display. The present invention solves the cost problem well by using the data collection method of the metering system; for the metering terminal concerned, the automatic recall mechanism is adopted, which solves the problem of poor real-time performance of historical data obtained from the metering system and relatively reduces the amount of data transmission , saving wireless communication traffic charges and reducing the pressure on the metering system.

Description

technical field [0001] The invention relates to the field of distribution network automation data collection, and provides an automatic collection method of distribution network load with low cost and high real-time performance. Background technique [0002] The distribution network dispatcher collects load data through the distribution network automation system and monitors the operation of the distribution network in real time. The existing distribution network automation load collection methods include the following two methods: [0003] 1. Deploy FTU equipment in the distribution network, and the distribution network automation master station directly communicates with the FTU equipment to obtain real-time load data. [0004] Advantages: Guarantee real-time data collection, fast transmission speed and high efficiency. [0005] Disadvantages: Due to the high cost of equipment, this method is generally suitable for small-area experiments, and the cost of achieving full ...
