油田电厂继电保护整定计算工作复杂,不确定性问题多,借助专家系统有助于解决此问题。设计了产生式规律表述法和框架表示法相结合的专家知识库,采用多级层次化的表示办法,提出利用正向推理和反向推理进行混合推理的推理机制。实际应用结果表明,本系统计算准确,实现了油田电厂继电保护整定计算工作的通用性和智能性。继电保护装置是油田电厂非常重要的设备,保护定值
Oilfield power plant relay setting calculation is complex, there are many uncertainties, with the help of expert system to help solve this problem. The expert knowledge base combining production rule representation and framework representation design is designed. The multi-level hierarchical representation is used to propose the reasoning mechanism of forward-reasoning and reverse-reasoning. The practical application shows that the system is accurate and realizes the versatility and intelligence of setting calculation of relay protection in oilfield power plants. Relay protection device is a very important oilfield power plant equipment, protection of fixed value
