【摘要】 建设继电保护及故障信息系统的目的在于提高调度系统信息化、智能化水平，使二次装置运行、管理的各个环节“可控、在控”，实现继电保护专业管理现代化，提升电网调度运行管理水平。继电保护及故障信息系统是一个继电保护运行、管理的技术支持系统，同时又是一个电网故障时的信息支持、辅助分析和决策系统。建设继电保护与故障信息系统，已成为继电保护运行管理部门的迫切要求，深入开展与之相关的理论和技术问题研究，具有重要的理论意义和很高的实用价值，然而对于继电保护及故障信息系统的通信结构，应用功能至今还没有系统化的解决方法。本论文围绕系统通信信息建模，应用信息建模、通信协议的映射以及系统数据高级分析和应用等几个主题开展了大量的研究工作。 针对目前继电保护及故障信息系统存在的接入装置或系统采用的通信协议互不兼容，无法实现装置或系统之间的互操作的问题，本文提出了继电保护及故障信息系统的分层通信结构以及主站和子站完备的通信信息模型。分层通信结构将系统分为通信层、数据层和应用层，规定了每层接口完成的功能。以系统的分层结构为基础，系统通信信息模型深入分析了继电保护及故障信息系统中子站和主站的通信功能，对子站和主站管理机逻辑节点、非兼容的IED逻辑节点和过程数据的封装逻辑节点进行了详细的描述和定义。为系统的互操作性、开放性、可维护性创造必要条件；减少了数据存储的冗余；屏蔽本地复杂性；降低系统维护成本。 为了将采用103／104通信协议的老装置纳入新的IEC61850通信体系，解决新旧系统通信的兼容性问题，本文在深入研究IEC61850的映射结构特点的基础上，开发了IEC61850到IEC60870-5-103／104通信协议的映射。讨论了将IEC61850到IEC60870-5-103／104规约的映射方法和思路，在过程层将ACSI中提供的过程层服务映射为IEC60870-5-103／104的ASDU(应用服务数据单元)来交换信息，并提出了具体的通信方案。 针对目前继电保护及故障信息系统在应用层存在的数据模型平面化、信息语义和通信语法耦合过于紧密的问题。本文提出了继电保护及故障信息系统的应用更多还原

【Abstract】 The goal of Relay protection and Fault Information System (RFIS) is monitoring and managing operation of relay protection. It is a technology support system as well as an information support, assistant analysis and decision system. To enhance the level of intelligent management in control center and control every part of IED in substation, the system is must be established. It has important theory and application value to research the related theoretic and technological problem. However, there is few people research the system on its structure, communication and application. The Dissertation does much research on the system and then draws valuable conclusions.For the relay protection and fault information system, a new hierarchical structure is proposed. The structure is divided three layers: communication layer, data layer and application layer. The interface of every layer is defined. The structure simplifies the design of RFIS. On the base of the hierarchical structure and use the modeling methods of IEC61850. And then, the communication function of RFIS in substation part and control center part is defined. The self-contained communication model based on the function is proposed. The substation device and control center device of RFIS is modeled as Logical Device (LD) and Logical Node (LN). The legacy devices and process data is also considered and is wrapped as LD or LN. The interoperability in RFIS is realized through above methods.A new mapping from IEC 60870-5-103/104 to IEC61850 is proposed. Using Specified Communication Service Mapping (SCSM) for reference, the mapping mapped the Application Service Data Unit (ASDU) of IEC 60870-5-103/104 to the communication model such as Server, Logical Device, Logical Node and Data of IEC61850 in process layer. Applying the mapping, the devices using IEC60870-5-103/104 can communicate with devices using IEC61850, which enhanced the compatibility of Relay protection and Fault Information System.A new application model of RFIS is proposed. The model is composed of primary更多还原
