| With the development of social economy, more and more demand for electricity, as animportant measure of the economic level of power supply is increasingly important.Electricity measurement for measuring the size of the battery "steelyard" for sale andpurchase electricity the interests of both parties, its importance is self-evidentThe annual power supply Guangdong power system of more than130billion kWh, do agood job of electric energy telemetering work plays an important role in improving powersystem economic operation level and enterprise management benefit. The electric energymetering and settlement usually rely on artificial regular site reading data and statisticalsummary, the resulting time difference and human error. Telemetering the application ofmodern computer communication technology in the measurement work, timely, accurately,comprehensively reflect the electricity purchase and sale of the situation, and provide reliabletechnical guarantee for the power market and power marketing. Economic system reformmakes the management mode from the single planned economy to market economy, theelectric power market has been a fundamental change. In recent years, network scale is moreand more large space truss structure more and more complex the power quality, safety,network loss, loss and other indicators are required to improve the power supply department,the concept has been updated. China’s electric power industry has long been the existence of"bad phenomenon retransmission, for light, don’t work", always attach importance toconstruction of power transmission facilities, attach importance to safety construction ofpower grid and the relative neglect of scientific means are adopted for power management,the use of a large number of artificial meter reading, artificial line loss calculation in theconventional manner resulting the timeliness of data is not high, the accuracy can not beguaranteed, the problem of higher operating costs and backward with the power managementhas become the bottleneck of the further development of China’s power enterprises electricitymanagement.Reform and technology of power system these years of progress, for the establishment ofelectric energy telemetering system in order to improve the electric power enterprise powermanagement automation level and operation management benefit to provide an opportunity,in the electric energy telemetering system through construction and put into use, electricenergy meter telemetry technology support system as the power marketing system and thegrid of the future commercial operation but also play an important role, there have been newequipment, new technology into remote metering system and obtained the popularization and application of good, after all these years of management operation, the system also began tomature, but also the inevitable problems, he comes from internal telemetering systemequipment, is also concerned with the management operation mode, the reality, reading thisfailure occurs during a data corruption, equipment failure, channel fault and so on a series ofproblems in the process are needed to address, at the same time it is also related to theelectricity settlement, line loss in power marketing analysis, working with electricalevaluation etc..Substation electric energy telemetering system as an important part of electric energytelemetering system, it is not only related to the operation and maintenance of metering devicegrid more influence analysis of electricity settlement, line loss in power marketing, workingwith electrical evaluation etc.. Therefore, the implementation of maintenance management ofsubstation electric energy telemetering system, solve the existing surface telemetering systemside issues, to seek a new way of thinking, new method, new technology, refining the resultsof the work, improve the power marketing management especially for metering operationlevel, to promote and improve enterprise economic benefits. |
