【Abstract】 The principles, structure and characteristics of a new fault recorder based on the technology of DSP+MCU double CPUs are described. The embedded and CPLD technologies are used in the device. The recorder has some advantages, such as high-speed samplings, high-accuracy measurement, continuous phase recording and recurring, and longtime fault recording, et al. If synchronoussampling based on the GPS is used in the devices, a dynamic monitoring and control system for power network will be erected.更多还原
