摘　　要：简要介绍了传统RTDS-GTNET的测试结构,并分析了智能变电站背景下对保护装置进行测试的实用化需求。针对测试需求,对更新的GTNET-SV模块技术进行了同步跟踪,对比了新、旧版本采样值(SV)模块的协议以及报文抖动情况,利用参数识别匹配的方法为RTDS与保护装置SV报文数据的正常交互提供了解决方案。以站域保护装置为实例,介绍了利用GTNET实现闭环测试的方法,并验证了测试的准确性。The test structure of traditional RTDS-GTNET is briefly introduced and the practical requirements for the test of protective equipments in smart substation are analyzed. Aiming at the requirements,the updated GTNET-SV module technique is synchronously tracked,the protocol and packet jitter of SV module are compared between new and old versions,and a solution applying the parameter-recognition-and-matching method to realize the normal SV message interaction between RTDS and protective equipment is proposed.With a substation area protection as an example,the implementation of closed-loop test based on GTNET is introduced and the test precision is verified.
