摘要
开发了一种以TMS320C32DSP为核心设计的新型低频减载装置,介绍了该装置的工作原理、硬件结构及软件设计。该装置能根据系统频率下降速率自动加速切负荷,缩短动作延时,有利于系统安全稳定运行。硬件系统结构简单,性能可靠;软件系统功能强大,充分考虑现场实际,人机界面友好。
A new under-frequency load shedding(UFLS) device based on TMS320C32 DSP is developed. The operation principle, hardware structure and software design are introduced. In order to reduce the time-delay of load-shedding, the device can shed load quickly according to the frequency decaying rate, which is good to the stable and secure operation of power system. The hardware system is simple and reliable. The software system has a powerful function and good man-machine interface.
