电力系统暂态过程同步记录的研究

摘要

电力系统暂态保护与控制具有广阔的应用前景，但通常的微机保护及故障录波满足不了其对高速同步采集的要求。文中设计了GPS同步高速采集系统，具有大容量的存储空间，能同步记录电力系统各变电站各种扰动作用下的变化过程。并介绍了基于同步高速采集技术的输电网故障行波定位系统。该技术已通过动模试验，记录准确，性能可靠。%Traditional data acquisition systems are difficult to satisfy the requirement of power system transient protection, control, and fault location. In this paper, a GPS synchronous transient data acquisition system with multichannel,GPS synchronous,high-speed recorder,larger memory is developed, which can recorder representations of the power system voltages and currents before ,during ,and after a disturbance. Based on the GPS synchronous transient data acquisitions. And a new fault location system with traveling wave is presented.
