摘　　要：根据波阻抗方向继电器的基本原理和特点 ,提出了其实现方案 ,设计了基于高速同步数据采集技术和数字信号处理技术的硬件构成方案 ,设计了软件框图和程序流程 ,方案设计中考虑了该继电器和其他继电器的配合。Based on the basic principle and properties of surge impedance relay, the implement scheme of the relay is proposed, which contains both hardware and software design. Fast and synchronous sampling techniques are adopted in the scheme of hardware, and fast digital signal processing (DSP) chip is used to realize the relay. In the design, the coordination of the designed relay with other relay has been carefully considered. Finally, the application of this relay in travelling wave based direction comparison protection is presented and discussed.
