61850故障信息系统主站、子站拟实现的功能基本参照现有系统的功能需求，并考虑国内61850保护目前能提供的信息、功能及限制。有关61850主站功能的细节（如如何体现61850特色）、各子站接线图的维护（如有的地方采用提供子站建模工具和文件召唤的方法）等特殊功能，待61850主－子站基本功能实现后进一步探讨。-61850 fault information system master, sub-station to be achieved by the basic functions with reference to the functional requirements of the existing system, and to consider the domestic 61850 protection of the current information, capabilities and limitations. Details on 61850 master function (such as how to reflect the 61 850 features), the maintenance of the sub-station wiring diagram using the method of modeling tools to provide sub-station and file calls (if any), special features, to be 61 850 main- sub-station further explore the basic functions.
