[Abstract]:The further construction of smart grid has put forward higher requirements for automation and intelligentization of relay protection, and the development of on-line application of relay protection has strengthened the operation monitoring of relay protection system. It is of great significance to improve the reliability of relay protection and the safety of system operation, and to promote the safe and stable operation of power grid. This paper focuses on the key technical problems of the on-line application of relay protection, and studies three aspects, such as on-line topology analysis in the plant and station, data matching of heterogeneous information system, visualization technology of checking calculation results, etc. The main contents are as follows: in the aspect of on-line topology analysis in the plant and station, a topology analysis method based on CIM model and the convergence of connection points and a fast tracking method of switch shift are proposed. The method directly utilizes the network topology CIM model, omits the process of building the adjacent table, completes the division and automatic numbering of the topology nodes in the plant station by layers, and adopts different processing methods for the different changes of the switches. When the complex switch disconnects, only a single terminal connectivity analysis is needed to complete the local topology correction, which improves the on-line response speed of the topology analysis. In the aspect of data matching in heterogeneous information systems, a new method of data matching and verification based on power network structure features is proposed. Considering the topology of power network, the method establishes coupling relation for the matching process of different types of data, which can easily deal with one-to-many and other complex matching relationships, and improve the success rate and accuracy of data matching. Reduced later maintenance work. In the aspect of visualization of calculation results in school, a three-layer progressive visualization system of online checking results of relay protection is designed. The design of the system takes into account the realization of the system function, the cognitive sensitivity of human beings and the progression of data, information and knowledge, which improves the readability and guidance of the online checking results of relay protection. The collocation of text and graphics, the combination of two-dimensional and three-dimensional, is convenient for relay protection personnel to obtain information and make decision.
