在電力系統(tǒng)中，繼電保護(hù)裝置為確保電網(wǎng)的安全穩(wěn)定運(yùn)行發(fā)揮著極其重要的作用。暫
態(tài)保護(hù)同基于工頻電氣量的傳統(tǒng)保護(hù)相比具有快速動(dòng)作的特性，但是，當(dāng)需要對暫態(tài)保護(hù)的 儀器進(jìn)行測試時(shí)，當(dāng)今的工頻繼電保護(hù)測試儀無法輸出高頻信號。基于此，本文提出的基于 DDS的暫態(tài)保護(hù)測試系統(tǒng)，可對暫態(tài)保護(hù)和工頻保護(hù)裝置進(jìn)行測試。

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.
