Design of high performance fault recorder
Dong Zhu · Dianli zidonghua shebei · 2003
The trend of today’s power system is continuous network expansion and LAN interlink.The performance of power system becomes increasingly complicated,which requires high performance fault recorders to analyze power system faults.The appearance of DSP(Digital Signal Processor),GPS(Global Positioning System)and Ethernet provides the essential conditions for the performance improvement of microcomputer-based recorder.A design scheme of fault recorder with high perfor-mances based on the above technologies is presented,including its hardware and software struc-ture and functions.The field tests show that the proposed device has many advantages,such as multi-monitoring-channel,high sampling frequency,good real-time performance,large data transmission capability and so on.
