设计了自适应变电站故障诊断专家系统(ASFDES)。该系统采用故障诊断自适应策略,能自动适应复杂多变的环境状态。ASFDES由多个子专家系统和核心专家系统组成,子专家系统应用基于规则的不精确推理机制实现快速的故障诊断,核心专家系统应用基于事例的推理机制来提高故障诊断的准确度。实验结果表明,ASFDES是有效的。 Design of adaptive substation fault diagnosis expert system (ASFDES). The system uses fault diagnosis adaptive strategy, can automatically adapt to the complex and ever-changing state of the environment. ASFDES consists of several sub-expert systems and core expert systems. Sub-expert systems apply rule-based inaccurate reasoning mechanisms to achieve rapid fault diagnosis. Core expert systems use case-based reasoning mechanisms to improve the accuracy of fault diagnosis. The experimental results show that ASFDES is effective.
