摘　　要：在10 kV新型配电网网络化保护中,受分布式电源广泛接入、运行方式复杂多变等影响,难以通过传统的单边测试对其网络化保护性能进行分析与论证。为此,首先分析了新型配电网网络化保护的整体架构与保护原理,并在此基础上搭建了与其一次拓扑相符的模型并得到不同故障类型下的PSCAD仿真数据,最后通过构造数据接口导入测试主机进行网络化保护性能分析与验证。该方法有效验证了保护装置逻辑的正确性与可靠性,提高了设备研发过程中的测试效率和测试质量,可为后续保护开发的性能验证提供借鉴和参考。In the novel 10 kV distribution network protection,it is difficult to analyze and demonstrate its network protection performance through the traditional unilateral test due to the wide access of distributed generation and complex operation mode.Therefore,the overall architecture and protection principle of the new distribution network networked protection are analyzed.On this basis,the PSCAD simulation data of different fault types are obtained.Finally,the performance of network protection is analyzed and verified by constructing data interface and importing it into test host.The method effectively verifies the correctness and reliability of the logic of the protection device,improves the test efficiency and quality in the process of equipment development,and can provide reference for the performance verification of the subsequent protection development.
