高性能故障录波器的方案设计

Design of high performance fault recorder

目前电力系统正朝着网络规模的不断扩大和区域网互联的趋势发展,电力系统也将会越来越复杂。电网的日趋复杂化对作为电网故障分析必不可少的故障录波器的性能提出了更高的要求。详细地介绍了高性能故障录波装置的软硬件结构和功能。此装置在现场试验中表现出监测通道多、采样频率高、实时性好、传送数据容量大等优点。

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.
