摘　　要：智能电网的发展对故障录波器提出了新要求,为此参考DL/T 663—1999标准,总结了基于IEC 61850的数字化故障录波器的性能特点。依据数字化变电站整体系统试验过程中对数字化故障录波器的考核要求,对故障录波器的试验方法进行研究。针对数字化故障录波器性能测试搭建测试系统,结合相关标准和检测经验总结录波器全面测试的项目,重点分析了面向通用对象的变电站事件(generic objectoriented substation event,GOOSE)报文规范性检查、采样数据品质位标识异常试验、采样数据同步位标识异常试验、采样值解码检查、采样值同步检查、GOOSE事件分辨率检查、对时和守时精度测试、报文实时监测告警和记录检查、开关量变位检查等测试项目及其技术要求,对数字化故障录波器测试过程中存在的典型问题进行分析并给出解决措施。Development of smart grid makes new requests to fault recorder, for this reason, referring to DL/T 663-1999 standard the performance characteristics of digital fault recorder （DFR） based on IEC 61850 standard are summarized. According to requirements for the appraisal of digital fault recorder during system-level testing of digital substation, the testing methods for digital fault recorder are researched. In allusion to the performance test of DFR, a testing system is constructed, and combining with related standards and testing experiences the test contents to be performed in overall testing of DFR are listed. In the listed contents, technical requirements of such testing items closely related to the performance characteristics of IEC 61850 as the inspection of the standard ability of GOOSE messages, the test of abnormal bit identification of the quality of sampled data, the test of abnormal bit identification of synchronization of sampled data, the inspection of synchronization of sampled value, the inspection of decoding of sampled value, the inspection of resolution of GOOSE events, the testing of time alignment and time-keeping accuracy, alarming of real-time monitoring of message and record inspection and inspection of switch signal alteration are emphatically analyzed. Typical problems existing in the testing process of DFR are discussed and corresponding solutions are given.
