摘要
一二次融合智能开关具备故障就地化处理高级功能,是智能配电网的典型特征,但如何测试其故障处理功能是一个难题,因此提出了高精度故障反演测试系统,为一二次融合智能开关故障测试奠定基础。通过分析目前传统的各种馈线自动化测试方法的不足,提出了基于一次侧故障注入的测试方法,解决了一二次智能开关全要素参与FA测试的问题。为实现就地式FA系统级测试,提出了基于HIL的一次侧故障注入就地式FA测试方法,采用仿真节点与实际测试台融合的虚实结合的技术,实现就地式FA系统级测试。
The primary and secondary fusion intelligent switch has the advanced function of fault local processing,which is a typical feature of the smart distribution network,but how to test its fault handling function is a difficult problem.Therefore,a high-precision fault inversion test system is proposed to lay a foundation for the fault test of primary and secondary fusion intelligent switches.Therefore,a high-precision fault inversion test system is proposed to lay a foundation for the fault test of primary and secondary fusion intelligent switches.By analyzing the shortcomings of various traditional automatic test methods for feeders,a test method based on primary side fault injection is proposed,which solves the problem of all elements of primary and secondary intelligent switches participating in FA testing.In order to realize the system-level test of in-place FA,a HIL-based primary side fault injection local FA test method is proposed.This test method adopts the combination of virtual and real technology of simulation node and actual test bench to realize local FA system-level test.
