|
摘要
制粉系统的自启停技术是实现燃烧全程自动控制的必备条件。对制粉系统启停时机及启停顺序进行了研究,建立了制粉系统的启停专家知识库,能够对其启停时机和启停顺序进行自动优化,实现了制粉系统在机组启停及运行全过程的智能控制;设计了双进双出制粉系统的自启停步序,实现了该类制粉系统启停过程的全程自动控制。应用表明,所设计的基于专家知识库的双进双出制粉系统自启停技术能够满足火电机组燃烧全程智能控制的需要,提高了机组的自动化水平和运行的稳定性。
The automatic startup and shutdown technology for coal-pulverizing system is the prerequisite for fully automated combustion control.In this paper,the startup and shutdown timing and sequence of coal-pulverizing system was studied,and then the corresponding expert knowledge base for coal-pulverizing system was established to automatically optimize its timing and sequence.and hence the intelligent full-process control was set up for the coal-pulverizing system during unit startup and shutdown operations.The sequential procedures of startup and shutdown process for double inlet and outlet tube mills was also designed.In this way the complete automatic process control for the coal-pulverizing system was realized.The application practice shows that the expert knowledge based automatic startup and shutdown technology for the double inlet and outlet tube mills can meet the needs of the fully intelligent control for combustion,which has greatly improved the automation level and operation stability of the plant.
