本文讨论了旋转式小型分散蓄发（DSG）装置与配电系统连接时的三个潜在保护问题的模拟结果。这些模拟是作为一项研究的一部分进行的，该研究旨在解决电力公用事业行业目前使用DSG配电系统的保护实践和硬件的充分性。模拟考虑了分散电源对进料的影响、熔断器的协调、三相DSG装置对馈线隔离段的共振以及DSG装置在隔离馈线上的孤岛等现象。这些现象被模拟了12年。带DSG的47kv馈线。利用数字计算机程序计算了三种现象在馈线上产生的瞬态电流和电压。仿真结果表明，这些问题是电力公司在将分散电源接入配电系统时应考虑的问题。
This paper discusses the results of simulating three potential protection problems associated with the interconnection of rotating-type, small dispersed storage and generation (DSG) devices to the electric distribution system. These simulations were performed as part of a study to address the-adequacy of the electric utility industry's present protection practices and hardware for distribution systems with DSG. The simulations considered phenomena such as the effect of dispersed generati, on infeed on the coordination of fuses, resonance of an isolated section of feeder with a three-phase DSG device, and the islanding of a DSG device on an isolated feeder. The phenomena were simulated for a 12. 47 kV feeder with DSG. A digital computer program was used to calculate the transient currents and voltages produced on the feeder for the three types of phehomena. Results of the simulations indicate that these are concerns which should be considered by electric utilities in the connection of dispersed generation sources to the electric distribution system.
