Based On The GIS Pumped Storage System Research And Development Analysis Of Power Plant Operation

Pumped storage power station is developing rapidly in the world power system, provide peak shaving, valley filling, forpower grid emergency standby, frequency modulation, phase modulation, fast load tracking and other functions, to improve the stability and reliability of the power grid, have played an active role. The construction of pumped storage plants started late in China pumping, twentieth Century 90’s along with the high speed development of national economy, power load increases rapidly, peaking contradiction is increasingly outstanding, the construction of pumped storage power station to solve the power peaking contradiction become the consensus of the industry, at present our country pumped storage power plant construction mainly concentrated in East China, North China, South China power grid energy storage. Pumped storage power station to improve the power grid thermal condition of operation,reduce the cost of power generation system, the remarkable social and economic benefits, but now its main benefitsembodied n (?)e capacity benefit and dynamic benefit or financial benefits are difficult to quantify. How to effectivelyconduct effective supervision of pumped storage power station operating efficiency will affect the future of pumpedstorage power station main problems of the healthy development of the.In order to solve this problem, the current operation situation of the main use of the static and dynamic benefits of twomodes of pumped storage power station is evaluated, in which the static benefit evaluation methods mainly include:the overall evaluation capacity efficiency, coal saving benefit, benefit; dynamic benefit evaluation method mainly has:the main benefit of frequency modulation, phase modulation, fault reserve benefit benefit black start, benefit and comprehensive benefit evaluation methods such as dynamic. Static benefits has formed a relatively maturecalculation method, the dynamic benefit evaluation is still in the exploratory stage, the main problem is that the evaluation method is not perfect, at the same time related data acquisition is difficult, so the synthesis of pumped storage power station operation in monitoring the use of information technology, extraction from the existing ERP,production management system suitable index a solid foundation for the future comprehensive use of various benefit evaluation technology to hit, and provide scientific basis for decision makers, is solved n the present stage of pumped storage power station efficiency key problems facing the development of.Currently GIS system has run in the land, transportation and other industries, as these industries provides visualization analysis and assistant decision-making, industry dynamic monitoring support capacity, greatly improve the level of informationization of the industry, so based on GIS technology to build a macro pumped storage to power plant operation evaluation system become the pumped storage can is one of the important research direction. The operation monitoring system for management provides such an operation analysis system, make them an intuitive understanding of the operation of power plant, provide a scientific basis for the management of power plant, and provide technical ideas for the era of big data analysis and processing.
