人们日益认识到大型火力发电机组对环境的影响，这激发了人们对安装在家庭或商业场所内的微型发电的兴趣。本文研究了从一系列微型发电机组，通常可以连接的瞬态响应。本文探讨了故障位置的影响，典型的故障清除时间和发电机/原动机技术的微型发电机保持稳定的能力时，受到干扰期间和之后清除本地低和远程中压故障。本文还介绍了阶跃电压的变化发生由于大量的微型发电机在一个小区域内的网络的同时重新连接的研究。两种类型的技术被认为是在本文中：一个小型的柴油发动机驱动的三相同步电机连接在商业楼宇内，和一个小的微型风力涡轮机接口直接在住宅内的单相感应发电机。
The growing awareness of the environmental impacts of large-scale thermal generating units has stimulated interest in microgeneration that is installed within domestic or commercial premises. This paper investigates the transient response to be expected from a range of microgeneration units that could typically be connected. The paper examines the impact of fault locations, typical fault clearance times and generator/prime mover technologies on the ability of microgenerators to maintain stability when subject to disturbances during and after clearing of both local low and remote medium voltage faults. The paper also presents the study of the step voltage changes occurring due to the simultaneous reconnection of a large number of microgenerators within a small area of the network. Two types of technologies are considered in this paper: a small diesel engine driving a three-phase synchronous machine connected within commercial premises; and a small microwind turbine interfaced directly within a residential dwelling by a single-phase induction generator.
