专家系统在湿式石灰石-石膏法烟气脱硫系统中的应用

Expert system application in wet limestone-gypsum flue gas desufurization

探讨专家系统在火电厂湿式石灰石-石膏法烟气脱硫(WFGD)工艺中的应用.该专家系统包括咨询子系统和控制子系统两部分.以知识库为基础,通过推理机调用,实现在湿式石灰石-石膏法烟气脱硫过程中的咨询帮助和故障诊断;通过对脱硫过程的仿真,实现参数监控和故障报警;结合脱硫效率的优化模型,实现系统优化;并实现专家系统的管理、权限和打印等功能.

Expert system is applied to the Wet Limestone-Gypsum Flue Gas Desulfurization （WFGD） of coal-fired power plant in the paper. And it consists of consulting subsystem and control subsystem. The consuhative help and faults diagnosis are implemented in the WFGD process, which are based on knowledge base and reasoning machine inference. Paraments monitoring and faults warning are also developed on the basis of desulfurization process simulation. The WFGD system is optimized with desulfurization optimization model. The improved expert system function, including management, permission and print, etc. are realized.
