FANUC 8705THA005S1W1NGL1(1) 依据锅炉对每个煤仓的加仓恳求,加仓前由运煤操控室的值班人员调出加仓画面,一起通过键盘输入给定加仓指令,完结主动加仓配煤。首要完结了分单元加仓功用。
(2) 加仓开端,先顺次给呈现超低煤位仓配煤,直至消除煤仓的悉数低煤位信号。
(3) 悉数的低煤位信号不见后,再进行次第配煤,当仓满后转到下一个煤仓进行次第配煤,直到悉数的煤仓满为止。
(4) 次第配煤进程中,假如又呈现超低煤位、低煤位仓,则中止原煤仓次第加仓程序,优先为超低煤位、低煤位仓配煤,消除超低煤位、低煤位,再转入次第加仓程序。
(5) 当悉数煤仓呈现满煤位信号(并报警)后,程序主动停机并把皮带上的余煤均匀分配给各煤仓。
(6) 在配煤进程中能主动越过满仓、高煤位仓、超高煤位仓及修理仓。
(7) 配煤的尾仓设定、修理仓设定均通过上位机进行设定,加仓时尾仓及其后方煤仓均不答应配煤。
5、界面显现
界面上首要完结了操控办法设置和流程挑选菜单,运煤技能流程图,实时运煤体系作业图,设备情况显现图,前史数据显现画面,毛病报警一览表,皮带机的作业显现,煤仓煤位的显现,各皮带、碎煤机、轮斗机电机电流的显现,悉数输煤体系的各个需要监督的有些均能在操作员站上显现出来,可以极好的避免输煤事端的发作,极大的进步了输煤体系的主动化水平。
6、结束语
将dcs体系运用到华祥热电有限公司的输煤程控体系中,可以极好的体现dcs体系的优势,将输煤体系需要监督的模仿量、开关量集成到悉数操控体系中,监督皮带的电机电流的改动,完结皮带上下级的连锁功用,完结主动加仓功用,进步了该电厂的主动化水平,也为将来厂级网络的互连预备了充沛的条件。科远厂级监控信息体系(SIS)的运用
SIS(Supervisory Inbation System of power plant),即火电厂厂级监控信息体系,是衔接全厂操控体系或智能外表的实时数据,包含DCS、辅佐车间操控、热网等,并以实时数据为根底,以安全经济作业和进步电厂全体效益为意图,在全厂方案内完结出产信息同享并为全厂实时出产进程归纳优化效劳的出产进程实时处理和监控的信息体系。它是完结从DCS体系到处理信息体系MIS的桥梁,然后在全厂方案内完结信息同享和管控一体化。
科远自2000年开端研制厂级监控信息体系(SIS),被评为2005年度国家要点新商品和中国软件职业协会的“2004年度优异软件商品”、“2005年度优异软件商品”。具有自立常识产权的SyncBASE实时数据库软件在国内电力职业中占有了主导的方位。此外该公司共获得了四项软件著作权、三项国家挂号软件商品、并获得了四项专利。
截止2008年末,科远已成功施行逾越数十个大中型电厂厂级监控信息体系项目,获得了用户的一起好评。
