【摘要】：利用智能变电站信息共享优势,提出了基于电流差动原理的站域后备保护方法,并开发了符合IEC 61850标准的智能变电站站域后备保护装置.为了验证站域后备保护装置的工作性能,提出了基于RTDS的全数字化保护测试系统方案.通过搭建变电站仿真模型,并配置GTNET-SV和GTNET-GSE模块,完成了站域后备保护装置的闭环测试.针对变电站正常运行、站内故障及站外故障等不同工况,测试了保护装置的动作逻辑和动作时间,其性能指标满足设计要求.
[Abstract]:Taking advantage of the advantages of information sharing in intelligent substations, a method of substation backup protection based on current differential principle is proposed, and an intelligent substation backup protection device in accordance with IEC 61850 standard is developed. In order to verify the performance of the backup protection device in station domain, a full digital protection test system based on RTDS is proposed. By setting up the substation simulation model and configuring the GTNET-SV and GTNET-GSE modules, the closed-loop test of the backup protection device in the station area is completed. According to different working conditions such as normal operation of substation, fault inside and outside the substation, the action logic and action time of the protective device are tested, and its performance index meets the design requirements.
