国产超(超)临界火电机组智能控制系统的工程应用

Engineering Application of PIC System in Domestic Supercritical/Ultra Supercritical Thermal Generation Units

国产超(超)临界机组智能控制(PIC)系统是以自启停控制系统(APS)技术和常规智能控制技术为基础的复杂系统,其工程应用的周期长、环节多,涉及多个单位、多个专业间的分工与合作,成功应用的难度很大。对该系统的工程应用要点进行了分析,提出了包括投资预算、职责分工、工期计划、实施流程等在内的整套工程应用方法,并介绍了该系统在国电哈密2×660 MW超超临界机组新建工程的应用实例。对各类火电机组PIC或APS系统的工程应用有很好的借鉴意义。

＂Thermal Power Unit Intelligent Control System＂ （PIC System） is a complicated system based on the unit auto startup and stop （APS） and the conventional intelligent control technologies. The engineering application of PIC system is hard due to the long application cycle, multiple stages, and the cooperation among different organizations and professions. In this paper, the key points of the engineering application of PIC system are analyzed and a complete set of engineering application methods are proposed which include the investment budget, the division of duties, the project scheduling and the implementation process. In addition, the application case of Guodian Hami 2 ×660 MW ultra supercritieal units is introduced. This case is greatly helpful for the engineering application of PIC or APS system in various kinds of thermal power units.
