为了准确、快速、全面地完成电网故障诊断功能，提出了基于多数据源的电网故障诊断系统。该集成系统利用事故级别信息、预警级别信息和故障记录文件，输出完整的诊断和跟踪报告。根据信息传输的时效性，将系统分为三个子系统：实时处理系统、准实时处理系统和批处理系统。完整的工作是通过他们之间的合作来实现的。实时处理系统在完成元件故障诊断的同时，还能筛选出误动作的保护和断路器，并判断事故级别信息的丢失。准实时系统在考虑部分警戒级别信息缺失的前提下，输出保护和断路器误动作的原因。批处理系统校正实时处理系统的诊断结果，并输出故障细节，包括故障阶段、故障类型、故障时间和故障元件的位置。仿真结果和测试结果表明，该系统在执行效率和故障诊断跟踪效果方面均能满足实际工程要求。可为电网的自愈和维护提供参考，具有较好的应用价值。
In order to complete the function of power grid fault diagnosis accurately, rapidly and comprehensively, the power grid fault diagnosis system based on multi-data sources is proposed. The integrated system uses accident-level information, warning-level information and fault recording documents and outputs a complete diagnosis and tracking report. According to the timeliness of three types of information transmission, the system is divided into three subsystems: real-time processing system, quasi-real-time processing system and batch processing system. The complete work is realized through the cooperation between them. While a real-time processing system completes fault diagnosis of elements, it also screens out incorrectly operating protections and circuit breakers and judges the loss of accident-level information. Quasi-real-time system outputs reasons for incorrect actions of protections and circuit breakers under the premise of considering partial warning-level information missing. The batch processing system corrects diagnosis results of the real-time processing system and outputs fault details, including fault phases, types, times and locations of faulty elements. The simulation results and test show that the system can meet actual engineering requirements in terms of execution efficiency and fault diagnosis and tracking effect. It can be used as a reference for self-healing and maintenance of power grids and has a preferable application value.
