该系统能进行诸如堆高温度和低锅炉效率检测，分析和诊断异常和低效率的工作条件。系统的某些特殊功能包括：在任何单位装载并根据正常和不正常的条件范围内电厂过程仿真。备件是一个工程上使用Gensym的G2的工作站实现面向对象的实时专家系统外壳上的250兆瓦发电机组建模在新加坡举行。是备用获得的知识被编码在工程模型和对象的形式。规则和数学模拟和公式。-A prototype real-time knowledge based system. SPARES (Steam Plant Analysis using a Real-time Expert System and Simulation) has been developed to act as an operational and diagnostic aid to operators of steam power plants. This system enables abnormal and inefficient operating conditions such as high stack temperature and low boiler efficiency to be detected, analysed and diagnosed. Some special features of the system include the simulation of the power plant process at any unit loading and under a wide range of normal and abnormal conditions. SPARES is implemented on an engineering workstation using Gensym s G2 object oriented real-time expert system shell modelled on a 250 MW generating unit in Singapore. The knowledge acquired for SPARES has been encoded in the form of engineering models and objects. Rules, and mathematical simulations and formulae. Efforts have been made to make the representation and reasoning structures and methods as generic as possible so that similar systems fo
