摘　　要：如何有效利用电网调度中心的大量数据进行电网故障诊断是一个重要课题。提出一种基于Tabu-RoughSet的电网故障诊断系统,包含数据采集、电网故障诊断、基于Web的电网故障诊断结果表示三个模块。在电网故障诊断模块里,利用Roughset理论对接收到的故障信息建立决策表并构成可辨识矩阵,利用Tabu搜索对可辨识矩阵寻找最优解,迅速准确地给出电网故障诊断结果。基于Web的诊断表示模块能够根据用户提出的查询请求采用可视化技术将诊断结果以基于网络的Web方式显示。实验结果表明,该系统能快速寻找最优解,较好地实现对电网故障的诊断。How to utilize the large scale data of dispatch center to solve the fault of power network effectively is very important. A new power network fault diagnosis system based on tabu-roughset is presented. It contains three modules, including data collecting,power network fault diagnosis and Web-based result display. In power network module, it utilizes roughset theory to form decision table on collected fault information,then to construct a discernibility matrix. Using tabu search can find the optimal result from the discernibility matrix, thus getting the correct power fault diagnosis quickly. The module of Web-based result display can provide the diagnosis with Web service according to the user＇s request by using visualization techniques. Experimental results show that the system based on the new method can find the best answer and better to achieve the power falult diagnosis.
