[Abstract]:With the progress of science and technology and the level of information, the scale of power system in our country is also increasing. The direct problem brought by the expansion of power network scale is that the requirement of power system reliability will be higher and higher. The development of power grid is facing new problems and challenges. In recent years, the IEC61850 substation based on IEC61850 international protocol has developed rapidly in China, but the corresponding networking technology and its reliability research are lagging behind. In order to improve the operation efficiency and reliability of IEC61850 substation, this paper focuses on the research of substation communication system based on IEC61850 standard. On the basis of referring to a large number of related documents and field practice, the network technology and simulation method of IEC61850 substation are studied. Reliability analysis and reliability promotion strategy are studied. The main contents are as follows: first, the characteristics of IEC61850 substation communication network are analyzed, such as: intelligent electronic equipment (Intelligent Electronic Device, IED) and electronic transformer replace the traditional equipment, the network data exchange method breaks through the traditional substation point-to-point data exchange mode, the digital signal replaces the analog signal exchange, the equipment adopts standardized modeling and unified description method. The development direction and the needs of networking research are analyzed, including equipment selection, topology planning, traffic delay analysis and so on. Secondly, the adaptability of OPNET network simulation software technology in the research of IEC61850 substation networking technology is analyzed, and the process layer network of substation is modeled based on OPNET, and its simulation is realized. The process layer of Yuci North Substation is taken as a case to simulate and analyze the process layer network. At the same time, on the platform of OPNET, the application of multi-link transparent protocol (Transparent Interconnectionof Lots of Links, (TRILL) technology in IEC61850 substation communication network is studied. The experimental results show that the process layer network of IEC61850 substation based on TRILL technology has advantages in network topology discovery and multipath transmission. TRILL technology adapts to the requirement of process layer network in network traffic and has strong adaptability in network convergence. Thirdly, the reliability description method of IEC61850 substation communication network based on relay protection reliability is put forward, and the influence of technical characteristics of IEC61850 substation on its network reliability is analyzed. Finally, the reliability analysis method of communication network based on message reachability is given. Taking the bus differential protection communication network of Yuci North Substation as an example, the reliability analysis method proposed in this paper is analyzed by a case study. Finally, starting from the important link in the construction cycle of IEC61850 substation-debugging, taking Yuci north substation as the engineering background, this paper gives the centralized connection adjustment preparation work, the SCD file configuration inspection work, Intelligent IED equipment interconnection experiment and system performance experiment and so on the suggestion. Aiming at the network test in Yuci North, the paper gives the test methods of the system, such as back-to-back frame number test, frame loss rate test, delay test and GOOSE transmission function test, which provides an effective strategy for improving the reliability of IEC61850 substation communication network. The whole thesis has carried on the massive research and the analysis from three aspects: the research based on the IEC61850 network, the reliability analysis and the reliability promotion method. The results are of great reference value and practical significance for the reliable and efficient operation of IEC61850 substation.
