从我国自主研发和生产的DCS成功应用于60万千瓦、100万千瓦超超临界机组,到首台*大容量60万千瓦超临界循环流化床机组DCS的突破,再到被称为核电站“神经中枢”的核电站全数字化仪控系统实现自主研发,近年来我国DCS实现了跨越式发展。
20世纪末,DCS在国内燃煤机组上应用时,其监控功能覆盖范围还仅*DAS、MCS、FSSS和SCS四项。即使在2004年发布的Q/DG1-K401-2004《火力发电厂分散控制系统(DCS)技术规范书》中,DCS应用的主要功能子系统仍然还是以上四项。“但实际上近几年DCS的应用范围迅速扩展,除了一大批高参数、大容量、不同控制结构的燃煤火电机组(如浙江玉环电厂100万千瓦机组)的各个控制子系统全面应用外,脱硫系统、脱硝系统、空冷系统、大型循环流化床(CFB)锅炉等新工艺方面都成功应用。可以说只要工艺上能够实现的系统,DCS都能实现对其进行可靠控制。”一位热工行业的负责人曾表示。
有专家分析认为,目前随着自动化控制技术的发展,火力发电系统的自动化程度也越来越高。在火电系统中DCS应用虽然说不是国内*早,但绝对是*广泛的。在火电的发展过程中,随着社会对电力资源需求越来越高,以往较为粗放式的发电已经行不通了,需要进更精细化的发电,以达到资源的*大利用率。而这种控制都需要靠自动化技术来实现,单纯的人工是达不到这种效果的。作为国家基础建设的重中之重,电力系统只能尽可能选用国产控制系统,来提高安全率。
“目前,主机控制和辅网控制采用DCS一体化的项目也愈来愈多。即在控制系统的高、精、尖上不断突破,在控制的范围上不断扩大,且国产化市场占有率增加势头也较猛,特别是在老机组DCS改造方面。近期,我们也拿到了DCS改造项目,为后续老机组DCS改造的国产化开了个好头。
