本文介绍了一种单相感应电机驱动的微型风力涡轮机连接到一个低压配电系统内的住宅。介绍了与电网连接以及本地和远程电网故障相关的瞬态。基于这些研究的结论将得出关于使用单相感应发电机的微型发电机的网络影响，相反，网络二次系统的影响，如保护（例如典型的故障清除时间）对这些发电机的行为，以及机器速度的阈值和其保留的终端电压时，系统经历远程故障的MV系统的定义。本文的主要贡献是突出与这种小型发电机的稳定性问题，并提出一些补救措施，这些发电机的稳定运行可能会得到改善。
This paper presents studies of a single-phase induction machine driven by a micro wind turbine connected to an LV distribution system within a residential dwelling. The transient associated with grid connection and both local and electrically remote network faults are presented. Based on these studies conclusions will be drawn regarding the network impacts of microgenerators using single-phase induction generators and, conversely, the impact of network secondary systems such as protection (e.g. typical fault clearance times) on the behaviour of these generators, and also the threshold values of the machine speed and its retained terminal voltage when the system experiences a remote fault on the MV system are defined. The principle contribution of this paper is to highlight stability issues associated with such small scale generators, and to propose some remedial measures by which the stable operation of such generators may be improved.
