Abstract:This study introduced the realization of a new monitor-controlling instrument of turbine protection system based on high performance DSP TMS320F2812. The signal of turbine measured by sensor was processed effectively by DSP or judged logically, then the result was outputted to PC, executive body or other instruments, in order to monitor and control the turbine. The protection system with this instrument is provided with many advantages, such as small volume, quick processing and high accuracy. Particularly, a few instruments can be collected by enhanced Control Area Network(eCAN) bus for realization of distributed real-time control.
