Method for evaluating clock state of power grid automation equipment based on data statistic analysis

Abstract

The invention provides a method for evaluating a clock state of power grid automation equipment based on data statistic analysis, and belongs to the field of power grid dispatching automation systems. The method is characterized in that after clock data are processed in a standardized mode, sample set data relevant coefficient evaluation, sample set data linear fitting and sample set data average errors are calculated, equipment operation analysis quantitative evaluation rules are constructed, the operating state and trend of an equipment clock are automatically judged, and clock information centralized monitoring, equipment abnormality alarming and intelligent judgment and evaluation are achieved. An energy management system, electric quantity metering management, a desulfuration monitor system plant device and a main station clock are managed in a unified mode, the equipment fault processing speed and the operation maintenance level are improved, and the good application prospects are achieved.

Description

technical field [0001] The invention belongs to the technical field of power grid dispatching automation, in particular to an evaluation algorithm of power grid equipment. Background technique [0002] With the rapid development of the smart grid, the dispatch automation system provides strong technical support for power safety production and commercial operation services. The equipment time of the power grid dispatch automation system is the basis for improving the data quality of the automation system and ensuring that the assessment and settlement information is "open, fair and just." "key. [0003] There are mainly three methods for clock management of existing automation equipment: one is to configure an independent standard time synchronization clock device, and synchronize time through serial port output, pulse active (passive) output or network mode. This method has the advantages of high efficiency and good precision of the synchronous clock, but the quality of the...

AI Technical Summary

Problems solved by technology

This method has the advantages of less investment in equipment and convenient operation and maintenance, but there are problems such as the timing accuracy is greatly affected by the quality of the channel; the third is to rely on the device's own clock device to realize the system's timing function

This method has the advantage of simple structure, but it has the problem of time error accumulation and requires human intervention.
