Research On The Constructionof Regional Power Dispatch Data Network

In recent years, with the concept of smart grid, the successive construction of digitalsubstation was put into operation for the safety of the electric power monitoring and controlsystem, reliable, flexible, efficient, convenient, etc requirements are put forward. Safetyelectric power monitoring and control system for the establishment of the goal is to meet the\"safe partition, network, horizontal isolation, longitudinal certification\" these features.Electric power communication network as an important component of the electric powermonitoring and control system also need to adapt to the direction of the development goals,meet the electric power monitoring and control system for important data informationtransmission and management requirements.Zhanjiang power grid power monitoring system of existing line transmission channellogically performance for many time slot, physical performance for audio jump line, terminalblocks, maintenance interface, the interface is not unified, large amount of maintenance, usingsuch shortcomings as the flexibility and extensibility. Obviously, the shuttle transmissionchannel can’t meet the requirements of electric power monitoring and control system in thenew period, to establish a new type of electric power communication transmission networkbecome inevitable.Booming in modern communications network technology, has changed from the originalvoice business to business transformation, data from the circuit switching technology topacket switching technology, the basic medium of optical transmission network constructionalso accelerating, various network rendering based on high speed to IP broadband datanetwork convergence, the next generation of softswitch network has started construction.Combined with the new network technology, we have established zhanjiang district electricpower dispatching data network to carry electric power monitoring and control system forimportant data transmission of information.This paper introduces the construction of the regional electric power dispatching datanetwork need to satisfy the real-time monitoring and real-time monitoring carrying more thantwo types of business, meet safety requirements under the connectivity of each node businesssystem, satisfy business effective Qos control, meet the1+1backup, network equipment suchas1+1redundancy requirements and related key technologies need to be solved. Zhanjiangdistrict electric power dispatching data network construction is through the IP over SDHtechnology on the SDH network of established network channel to reach the business requirement, VPN (virtual private network) to implement electric power dispatching controlcenter and the relevant power plants, substations, business systems interconnection. Then, thispaper takes zhanjiang electric power dispatching data network dispatching data networkconstruction for case analysis and research process. Finally combining actual application, bycomparing the transmission line channel to analyze zhanjiang electric power dispatching datanetwork application conditions and advantages.Zhanjiang district electric power dispatching data network business at present is mainlyfor EMS system, the next will be connected to the electric energy metering system, prudentialsystem, voice dispatching system, etc. Electric power dispatching data network to replace theshuttle transmission channels become the bearer of the electric power monitoring and controlsystem for important data communication network is the inevitable trend.
