A time-sharing task collection method for power grid electric energy metering system

Abstract

The present invention discloses a time-sharing task collection method for a power grid electric energy measuring system. The method comprises the following steps of: S1, acquiring a collection task issued by a master station; S2, setting a time interval value, wherein the time interval value is smaller than collection time corresponding to the collection task; S3, carrying out segmentation on the collection task according to the time interval value to acquire collection sub-tasks in a plurality of consecutive time periods; S4, executing the collection sub-task of which start time is arranged in the most front according to a time sequence, and determining whether the current collection sub-task is successful; and S5, when the current collection sub-task is completed successfully, determining whether the collection task is completed. According to the method, the collection strategy is dispersed into different tasks by establishing the time-sharing task, the competeness of the collection is controlled by controlling the task, and even if anomalies occurs (conditions of network interruption, device anomaly of sub-stations and the like), data collection only needs to be completed continuously without human intervention after the anomalies are recovered.

Description

technical field [0001] The invention relates to the technical field of power grid data collection, in particular to a time-sharing task collection method of a power grid electric energy metering system. Background technique [0002] Grid electric energy metering system has become another basic function of grid dispatching automation after the functions of SCADA (Supervisory Control And Data Acquisition, data acquisition and monitoring control system) and AGC (Automatic Generation Control, automatic generation control). It plays an important role in the process of the market. The electric energy metering system of the grid mainly uses modern communication technology, information processing technology, storage and release technology to realize remote control of metering point data such as gateways, power plants, substations, distribution transformers, and large users. Automatic collection. At the same time, it realizes interconnection with load control system, dispatch manage...
