摘　　要：故障诊断是未来智能电网可自愈的前提条件。为了进一步提高电网故障诊断系统的效率及准确性,文中提出了一种以数据网格为支撑、分布式系统为主体的新型电网故障诊断架构。数据网格可以提高故障诊断系统数据采集的实时性和可靠性,而分布式系统提供的分布式计算技术能够极大地提高诊断程序的运行速度。两者的结合能够使这种新型的诊断系统在诊断速度及准确性上优于传统的客户/服务器(C/S)结构。最后,通过案例证明了新系统的可行性。Fault diagnosis is the premise of the self-healing of smart grid in the future.In order to promote the efficiency and accuracy of the fault diagnosis system,this paper puts forward a new kind of power grid fault diagnosis framework.It is supported by data grid and its main skeleton is the distributed system.Data grid provides reliable data to the fault diagnosis system in time while the distributed computation supplied by the distributed system can enhance the execution speed of the fault diagnosis program.The new diagnosis system including the data grid and distributed computation is obviously superior to the traditional C/S structure.Finally,the validity and feasibility of this method are testified by examples.
