Abstract

Distributed generation (DG) produces many benefits for the distribution systems that are operated as active systems, even if they have been traditionally designed as passive networks. Then, new technical issues must be addressed, involving both normal and abnormal operating conditions such as short circuits. Photovoltaic systems (PVSs) are among the most diffuse DG and their contributions to the short-circuit operating conditions depend on several factors, such as environmental conditions, PVS inverter control characteristics, self-protection systems, and fault location and type. An analytical model that aims at quickly and accurately analyzing the three-phase short-circuit operating conditions in a distribution system in presence of PVSs is presented in this paper. The model is applied to a typical North American MV network characterized by large penetration of PVSs, investigating the influence of the aforementioned factors.

光伏发电机组三相短路工况的影响

分布式发电(DG)为作为有源系统运行的配电系统带来了许多好处，即使它们传统上被设计为无源网络。然后，必须解决新的技术问题，包括正常和异常操作条件，如短路。光伏系统(pv)是最分散的DG之一，其对短路运行条件的贡献取决于几个因素，如环境条件、pv逆变器控制特性、自我保护系统以及故障位置和类型。本文提出了一种分析模型，旨在快速准确地分析有pvs存在的配电系统三相短路运行情况。将该模型应用于一个典型的北美MV网络，该网络的特点是PVSs的渗透率很大，研究了上述因素的影响。
