摘　　要：针对水泥生产余热发电系统手动操作并网步骤多、并网时间长、易发生误操作的问题,开发了使用SFC语言编程的一键并网全自动控制技术。一键并网技术通过将励磁系统、同期系统、汽轮机电液调节系统、断路器状态点等信号均接入DCS系统,优化软硬件配置,增加新的顺序控制及逻辑判断,利用SFC编程语言进行编程控制,最终实现一键自动并网。实践表明,一键并网技术操作简单,运行可靠,后期运行成本降低,并网操作时间可由3~5min缩短至1~1.5min,并网成功率较高,误操作率降低。In view of the problems of many operation steps,long grid-connection time and easy misoperatio in the manual grid-connection process of WHR in cement line,One-key grid-connected automatic control technology with SFC language was developed.The one-key grid-connected technology integrated signals such as the excitation system,the synchronization system,the steam turbine control system,and the circuit breaker status points into the DCS system,optimized the software and hardware configuration.Then added the new sequence control and logical judgments.Finally,one-key grid-connected was achieved with the SFC programming language.Practice shows that using the implementation of the One-key grid-connected technology,the operation was simple and reliable,the later periods was reduced,the grid connection operation time could be shortened from 3~5minutes to 1~1.5 minutes,the grid connection success rate was high,and the misoperation rate was reduced.
