Abstract

With increasing penetration of multi-inverter photovoltaic (PV) systems into the distribution network, concern is beginning to reemerge regarding the possibility of multi-inverter unintentional islanding. This paper discusses a study to probe anti-islanding and voltage rise issues for a specific hybrid anti-islanding method (common to many commercial inverters) in a proposed high-penetration PV installation at a residential development in Salem, MA. Two sets of studies were run, one involving the specific feeder involved in this installation, and the other a more generic study that deliberately sought the Non-Detection Zone (NDZ) of the hybrid anti-islanding method in the multiple-inverter case. The paper discusses the results of both of these studies, and makes recommendations to assist utilities in deciding when anti-islanding studies might be needed in fielded systems.
公寓楼中多单相逆变器的高渗透及抗孤岛分析
随着多逆变器光伏系统日益深入配电网,多逆变器意外孤岛的可能性再次引起人们的关注。本文讨论了一项研究,以探讨在马萨诸塞州塞勒姆的一个住宅开发项目中拟议的高渗透光伏安装中的特定混合防孤岛方法(许多商用逆变器常见)的防孤岛和电压上升问题。进行了两组研究,一组涉及该安装中涉及的特定馈线,另一组则是更一般的研究,旨在寻找多逆变器情况下混合反孤岛方法的非检测区(NDZ)。本文讨论了这两项研究的结果,并提出建议,以协助公用事业公司决定何时可能需要在现场系统中进行反孤岛研究。
