Power dispatching data design

power dispatching network design technology, including two parts: dispatching automation system and power dispatching data. Among them, the data transmission network platform of power dispatching data network is a prerequisite to realize the remote dispatching network technology. Network design will directly affect the transmission quality of network signals and give play to the key advantages of network transmission. After the power dispatching is completed, the data of all communication levels between the power dispatching data terminal structures will be connected to the network. In addition, the remote terminals of substations at all levels access these data, and the data is transmitted to the data analysis of SCADA system. The real-time operation of substations has been realized through the network remote SCADA system technology

1 design principles for new materials such as high-performance carbon fiber, vanadium titanium, high-temperature alloy

the design of power dispatching data network should reflect advanced, real-time and economic characteristics, so that the design has a network of high reliability, expandable parts, standardized parts and manageability. The design of the network should respond to the oil leakage of the oil circuit system. Nowadays, the connection of buffer valve, oil return valve, oil delivery valve, oil pump and pipeline provides different network service services, and provides a unified information system for all types of broadband integrated service networks. In the local network design, we should mainly pay attention to the following aspects:

1) the network design should have higher transmission bandwidth and higher throughput and efficiency under higher load

2) in the network design, different underwater services should be provided according to the business needs, and the functions of shunting control, packet classification, flow shaping, etc. should be provided for customers

3) the network should be designed to ensure the installation of the whole system and the ability to prevent human destruction

4) the network design should be convenient to add new equipment, which can realize the connection with the relevant network. The application program can be continuously mature, and the system can be continuously extended and expanded to maximize the use of existing resources

5) the network design should meet open standards, and you can choose equipment from different manufacturers

6) the design of communication protocol and connection u should be consistent with international standards

7) the network design should be very economical and flow with the characteristics of centralized and large amount of information of backbone network structure and technology

8) the network system should be easy to manage. The network plastic tensile testing machine is cheaper than those instruments with digital control boards that have been used for more than 10 years. The configuration of the management system can easily manage the whole network

2 network reliability

in order to avoid network channel failure and improve the reliability of the network, the linked independent parts should meet the principle of n-1, and multiple links caused by single point failure of the network should be avoided to break at the same time, resulting in splitting and reducing the data network partition of the network

3 network performance

the indicators to measure network performance include network delay, cloud packet rate, network convergence time, available parts and other network performance indicators. These factors should be considered in terms of its scale topology, transmission quality, bandwidth, equipment configuration and other factors related to network design

the standardization of data transmission network to provide "best effort" services. Based on the mechanism of fif0, all data packets are treated equally. The reliable components and delay performance of their transmission cannot be guaranteed. When the network is stable and uninterrupted, the performance index of the scheduling network meets the business requirements. The expansion of network traffic and bandwidth caused by the increase of business growth can also be solved. When the sudden increase of network failures and traffic congestion, real-time scheduling services provide a strong guarantee

deploying QoS on the dedicated network of power dispatching data should not increase the complexity of the system, while ensuring the principles of network management and maintainable components. If you can simplify the core network, and the edge of the network is slightly more complex, it is still an ideal solution

4 network management

network management can usually be achieved through in band and out of band methods. Considering the cost and technology of out of band management network, power dispatching is the usual way. The management system is through the establishment of a centralized management system. The whole network system is under centralized management. The host system is responsible for network management and network device application management. The equipment used for information management and the employment of some local people will be stored in the network database, and the network equipment in the border areas will be handled by the management center

establish a regional network management center system to be responsible for network management. The network management system should provide a form of parent activity, and the client browser and various network devices should be managed uniformly. The network management system shall have the following functions: topology management, configuration management, fault management, equipment management, performance management, installation management, and billing management. At the same time, the network management system should provide users with Exploitable secondary network interfaces
