摘　　要：小电流接地系统行波法选线装置是实际应用的机型之一,对其性能的多方面检验有助于其不断完善与发展。介绍了基于行波法的选线方法,分析了利用实时数字仿真器(RTDS)测试小电流接地系统行波法选线装置的可行性,建立了基于RTDS的行波法小电流接地系统仿真平台,由仿真结果证明建立的仿真平台一定程度上适用于该类装置的检验。The apparatus for fault line selecting based on transient traveling waves in the neutral un-effectual grounded system（NUS） is one of the types of facilities used for practical applications.Performance testing using real time digital simulator（RTDS） provides helpful information for its improvement.This paper introduces methods of using transient traveling wave signal（TTWS） to faulty line selection.The feasibility for testing the apparatus based on TTWS using RTDS is analyzed,and a NUS simulation platform is built for TTWS based on RTDS.Simulation results demonstrate the platform is suitable for testing such apparatus to some extent.
