2.采用DCS系统实现ETS功能的优点及存在的隐患
近年来,各新建电厂在设计机组热工控制系统时,几近普遍采用了DCS系统一体化设计,即一套DCS系统包括了FSSS(汽锅平安监控系统)、CCS(协调控制系统)、SCS(顺序控制系统)、DAS(数据收集系统)、DEH(汽轮机数字电液调理系统)、MEH(小汽机电液调理系统)、ECS(电气量控制系统)和ETS系统。但若何经由过程DCS系统靠得住地实现汽轮机紧急跳闸庇护功能,相关的行业规程并没有作出具体划定,是以,设计人员只能凭据所采用的DCS系统特点和小我经验,将原继电器逻辑所实现的庇护功能,由DCS系统的软件逻辑实现,因而不成避免地对ETS系统抗庇护拒动和误动的能力带来一定的影响。ETS庇护功能两种实现方式的优错误谬误对好比表一所示。
