Research On Wireless Communication Key Technologies In Power Demand Side

With the development of the power industry,power communication networks,especially to Power Demand Side(PDS)wireless communication networks which are the power distribution networks below 10KV,are becoming more digitalizing to support the transmission of more information and services.All these features and trends above give more requirements and challenges to PDS wireless communication network.This Thesis firstly summarizes the design and the optimization in PDS wireless communication network to depict the related key technology issues.To solve the related media access control issue,a hybrid access control algorithm is proposed,which performance and effectiveness are demonstrated by the modeling analysis and experiment simulation respectively.To solve the related resource allocation issue in wireless channel,a PDS-based channel allocation strategy is suggested,which is implemented by means of time-reporting mechanism,error-retransmission mechanism and warning mechanism respectively.The thesis tries to provide some advice to promote the construction and optimization of PDS wireless communication network.
