摘要

论述了适用于含分布式电源(DG)配电网故障性能测试的改进主站注入测试法的平台组成和工作原理，论述了含DG配电网潮流计算和短路电流计算方法，提出了故障场景自然设置法，根据所设置的故障场景下短路电流的计算结果和继电保护定值、配电终端定值、自动装置的设置情况等自动判断是否应该保护动作跳闸、自动装置动作、上报相应的故障信息等，可以对健全区域恢复供电过程中的不当操作引发的开关动作或DG和电压敏感负荷脱网进行模拟，从而更加有效地对配电自动化系统的恢复策略和操作步骤的正确性进行测试检验。最后，给出测试实例详细说明了所论述的测试技术的可行性和有效性。

Abstract

The composition and principle of the improved host injection test platform for fault handling performance test of power distribution network with distributed generators(DGs)is described. The power flow calculation method and short circuit current calculation for the power distribution network with DGs are discussed. A natural fault scenario set-up approach is put forward. The action of relay protections

automatic devices

feeder terminal units(FTUs)and circuit breakers are simulated according to the comparison of short circuit calculation and the setting values. In addition

the action of switches and DGs separate from the grid during the restoration procedure can also be simulated. Thus

the correctness of the scheme and steps of service restoration can be tested more effectively. Examples are given to illustrate the feasibility and effectiveness of the test technology proposed.
