【摘要】：智能电网的深入建设对继电保护的自动化、智能化提出了更高的要求，继电保护在线应用的发展对加强继电保护系统的运行监视，提高继电保护的运行可靠性和系统运行的安全性，促进电网的安全稳定运行具有重要的意义。本文围绕继电保护在线应用的关键技术问题，对厂站内在线拓扑分析、异构信息系统数据匹配、校核计算结果可视化技术等三方面进行研究，主要包括如下内容： 在厂站内在线拓扑分析方面，提出了基于CIM模型和连接点汇集的拓扑分析方法及开关变位的快速跟踪方法。该方法直接利用电网拓扑CIM模型，省略了建立邻接表的过程，分层完成厂站内拓扑节点的划分和自动编号，，对开关的不同变化采用不同的处理方式，当复杂的开关断开发生时仅需进行单端的连通性分析即可完成局部拓扑修正，提高了拓扑分析的在线响应速度。 在异构信息系统数据匹配方面，提出了基于电网结构特征的数据匹配及校验新方法。该方法加入了对电网拓扑结构的考虑，对原本分割开来的各类型数据的匹配过程建立耦合关系，可方便地处理一对多等复杂匹配关系，提高了数据匹配的成功率和准确率，减少了后期的维护工作。 在校核计算结果可视化方面，设计了三层递进的继电保护在线校核结果可视化体系。该体系的设计兼顾了系统功能实现、人的认知敏感程度和数据、信息、知识的递进，提高了继电保护在线校核结果的可读性和指导性。文字与图形的搭配，二维与三维的结合，便于继电保护人员进行信息获取和判断决策。
[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.
