| 摘要: |
| 为提高我国小水电站的自动化技术水平,实现小水电站无人或少人值班的要求,提出了一种集发电机保护、综合测控、励磁控制、同期控制、顺控、远程通信等功能组合的智能一体机。该一体机采用多CPU的硬件模式,由于一体机内部的运算量大,实时性要求高,主控制器采用DSP56F807,内部各功能模块采用CAN总线相连,一体机与上位机之间采用工业以太网相连,通信快速可靠、抗干扰性强。该机结构紧凑,便于安装使用,在现场可独立运行及操作,在多机系统联合运行时又可根据需要配置上位机,构成水电站监控系统。 |

| Abstract: |
| A measuring and control device,integrating the functions of generator protection,measuring and control,excitation control,synchronization control,sequential control and remote com-munication,is brought forward to improve the automation of small hydropower stations and realize unmanned operation.It adopts multi-CPU mode and choose DSP 56F807 as master controller for real-time multi-functional operation.CAN bus is used to connect the inner functional modules,and Ethernet is used for reliable communication between device and PC.With compact structure,it is easy to stall.It can run independently or communicate with PC to form a monitoring and control system as multi-machine system. |
| Key words: measuring and control device,DSP,CAN bus,automation in small hydropower station |
