基于DDS 的暂态保护测试系统的研制

在电力系统中，继电保护装置为确保电网的安全稳定运行发挥着极其重要的作用。暂
态保护同基于工频电气量的传统保护相比具有快速动作的特性，但是，当需要对暂态保护的 仪器进行测试时，当今的工频继电保护测试仪无法输出高频信号。基于此，本文提出的基于 DDS的暂态保护测试系统，可对暂态保护和工频保护装置进行测试。

Design of Transient-State Protection Testing System based on DDS Liu Bo,Shu Kang, Hu SanQing (Electronic Information Engineering Department, Hua Zhong University of Science and Technology,Wuhan 430073,P.R.China) Abstract:Relay protection devices to ensure the safe and stable operation play a vital role in power system.Compare to the tradional frequency protection, transient-state protection moves more nimble.But when the need for transient-state protection devices for testing, tradional frequency relay protection testing devices don’t output high frequency signals.So this paper introduces a kind of transient-state protection testing systems based on DDS,which can test both the transient-state protection and tradional frequency protection devices.
