Abstract: After the characteristics and functional demands for network management in the new generation smart substation are analyzed,the overall framework and function deployment scheme of the communication network management system are proposed by cutting down the architecture and functional model of the telecommunication network management system.The key technologies of the network topology automatic mapping,service of automatic discovery and creation,visualization of physical loop and virtual loop are also developed.With the Fengqiao substation project in Shaoxing City as an example,the feasibility of the proposed scheme is verified.After the scheme is widely used,the capabilities are enhanced and the costs are reduced in the operation and maintenance management system.
