摘要 Subject: Validation research of power load management system 0f 230MHz cellular network Specialty: Control Theory and Control Engineering Name: Qiu Yunpeng Supervisor: Diao Hainan Liu Yuemin ABSTRACT Electric power load management system（PLMS） is an important part of the power marketing and power demand side management （DSM）. Because the PLMS coverage is from the original large electricity users to a vast number of medium and small power users, the number of terminal users is increasing fast and the amount of data which need to be collected become bigger. Therefore, the old control mode of 230MHz wireless private centralized network can not meet the requirements of current mission. It is necessary to build a more powerful communication network. In order to comply with the requirements in On speeding up the modernization of the power of marketing guidance which was made by the State Grid Corporation of China in June 2005, to make full use of the advantages, good security performance and high availability, of 230MHz wireless private centralized network, and to resolve the problems existing in the power load management system at this stage, a new electric load management system which is based on the cellular model of communication network is proposed and tested. Firstly, this dissertation based on the theoretical analysis of the cellular networking in 230MHz wireless private network, the main features and technical parameters of the power load management system are determine. And then the design of power load management system which is based on 230MHz cellular communication model is proposed.The hardware theoretical design of base stations and terminal test equipment of the completion the power load management system is completed. Base stations and terminals use the same hardware design and the conversion between base stations and terminals is through remote upgrades. Hardware design mainly include
