| 摘要: |
| 分析了目前国内大型发电厂中厂用电气监控管理系统的应用情况,提出厂用电气监控管理系统可采用“硬接线 通信”方式(控制保留I/O硬接线,监测采用通信)、“保留关键硬接线 通信”方式(少量重要电动机控制保留I/O硬接线,其余设备控制及全部监测采用通信)和“完全通信”方式(控制及监测全部采用通信)3种设计方案。对3种方案分别从系统结构组成、功能应用、可靠性等方面进行了分析,并对综合投资相应进行了经济比较。现场实际运行结果表明,推荐采用的“保留关键硬接线 通信”方式具有较高的性价比。 |

| Abstract: |
| The application of auxiliary power supervisory control systems in large power plants is analyzed and three designs are put forward:"cable connection communication"(cable connection for control and communication for supervision),"crucial cable connection communication"(cable connection for control of crucial devices,communication for control of normal devices and supervision)and "complete communication"(communication for both control and supervision).Research on them is made from system structure,function application and reliability,and integrated investments are also taken into consideration.Practices show that,the second design has better performance-cost ratio. |
