Method for achieving data automatic collection of plant station electric energy collection terminal

Abstract

The invention relates to a method for achieving data automatic collection of a plant station electric energy collection terminal. The method comprises the steps: first of all, electric energy meters with data needing to be collected are added in the plant station electrical energy collection terminal, and meter reading channels through which the electric energy meters are connected into the collection terminal are taken as a unit to conduct managing; then the meter reading channels are taken as the unit in the plant station electric energy collection terminal to start an electric energy meterdata collection and processing task, whether the data needing to be collected exist or not is judged every second, and the judgment basis is the preset data automatic collection time interval; and when the timing data collection time meets the requirements, the corresponding data of the electric energy meters in the meter reading channels are collected. The application flexibility and extendibility are improved, the accuracy and real-time performance of the automatic collection interval are guaranteed, an interface is separated from implementation, collection implementation procedures of the various electric energy meters are efficiently managed, and the high cohesion and low coupling between procedure modules are achieved.

Description

technical field [0001] The invention belongs to the technical field of power system data collection, and in particular relates to a method for realizing automatic data collection of power station electric energy collection terminals. Background technique [0002] With the advancement of power system automation and intelligent technology, the automation requirements for data collection are becoming more and more common. The power supply company's collection of various data on the plant side has gradually reached the status of automatic collection, basically realizing the systematic automatic collection and analysis of various data. Most of the collection devices on the plant side are intelligent terminal devices based on embedded systems, and the electric energy collection terminal of the plant station also belongs to this type of embedded system equipment. In the electric energy collection terminal, all electric energy meter data in the substation must be completed periodica...
