The Transformation Of Jiande Power Supply Company 110kV Substation’s Communication Transmission Network

Transmission network, which is the core of the electric power communication network, carrying a large number of production and management of the business, is the assurance of safety production and stable operation of power system, is the foundation of automation of power grid dispatching, marketization of network operations and management modernization, is to ensure that an important means of power grid security, stability and economic operation.According to the present situation of Jiande power supply company’s optical transmission network, and the future development direction of electric power communication network, and change the way of power grid company business application requirements, the paper put forward the reforming jiande power supply company 110kV substation communication transmission network.Idea mainly from the following four aspects to discuss and research, and form one of the most suitable scheme for building jiande company transmission network eventually.One is based on the current mainstream communication transmission technology of SDH, MSTP, ASON, DWDM, analyzing its advantages and disadvantages respectively, and according to the company’s application requirements and development, optimizing MSTP as a technology platform of choice for reform.Secondly, the analysis of currently used several communication transmission network topology form, according to its scope of application and the present status of the fiber optic cable topology, identify using the ring network and mesh network to mix way of networking.Thirdly it is according to the current business traffic type and bandwidth of communication transmission network, combined with SGC traffic planning, forecast the future five years business flow.Four is according to the calculated business flow, the selected platform technology and network mode, to determine each communication site’s panel and business configuration.At last, through the above research results to build 110 kV substation communication transmission network.When jiande power supply company 110 kV substation communication transmission network’s reconstruction is completed, it will further improve the company’s communication network security, reliability and survivability, and improve the network’s business support ability, resilience and higher access ability, more flexible bandwidth for building safety, high quality and economic operation of Jiande power grid company.
