Design Of Electric Energy Data Acquisition System For Power User

with the rapid development of electric power marketing modernization in recent years, the power user electric energy data acquisition system has been given a higher,more sophisticated requirements. The single acquisition mode once for low voltage users,public distribution transformer, special transformer users, mark has shown more and more disadvantages, establish a set of the supply side, the sale of electricity, electricity purchase side integrated electricity information acquisition system is more and more urgent.This thesis designed the electric information acquisition system of the user, aiming at the requirements with "full coverage, full collection, full prepayment" of Power Grid Corp in Hebei province. First of all, introduced the development and the classification of electric information acquisition technology recent, then expounded the solutions to support multi-channel, multi service, fully using the hierarchical design method and realizes the electricity information collection system. This system used the data acquisition function as the core, from the function of covering power functions related to information collection service in the SG186 marketing service application, the direct acquisition of large, medium and small terminals of special transformer terminals of special transformer, and concentrator with a communication function of electric energy meter, extensible collection of small hydropower, small thermal power, the Internet gateway the substation metering point and gateway electric energy data. The electric energy information acquisition and processing to achieve the unification of purchasing side, the supply side, the sale side of three aspects, the construction of power information platform to perfect.The construction of electric information acquisition system for the power user can effectively improve the metering, automatic meter reading, marketing services such as prepaid processing automation of electric energy, coule improve the overall level of marketing management. "SG186" can provide accurate business applications and complete data support, to meet the professional needs of all levels of the system, the power of information to promote the modernization of management, improve the level of corporate.
