【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]:This paper discusses the platform composition and working principle of the improved main station injection test method suitable for fault performance test of (DG) distribution network with distributed power supply, and discusses the calculation methods of power flow and short circuit current of distribution network with DG. The natural setting method of fault scene is put forward. According to the calculation results of short circuit current and relay protection value, distribution terminal value, automatic device setting and so on, whether the protection action should be tripped or not should be judged automatically. The automatic device action and the corresponding fault information can be used to simulate the switch action or DG and voltage sensitive load disconnection caused by improper operation in the process of restoring power supply in a sound area. Thus, the correctness of the recovery strategy and operation steps of the distribution automation system is tested and verified more effectively. Finally, a test example is given to illustrate the feasibility and effectiveness of the test technology.
