摘要

针对分布式光伏发电接入配电网发生孤岛效应对电力检修人员现场安全作业的影响，设计了一种应用于220 V/380 V配电网中的低压反孤岛装置。装置基于光伏发电的孤岛运行机理和防孤岛保护策略，通过破坏分布式光伏发电孤岛运行的条件，实现反孤岛功能。提出了3种类型（阻性、感性、容性）低压反孤岛装置的设计原理，结合工程实际，计算了系列化低压反孤岛装置设计参数。通过试验对设计原理进行了验证和分析，通过比较不同类型低压反孤岛装置的试验结果和负载特性，建议低压反孤岛装置优先选用电阻型扰动负载。

Abstract

Aimed at the impact of the islanding effect on field safety work by power maintenance personnel with distributed photovoltaic generation connected to the distribution network

this paper presents a low voltage anti-islanding device used in 220V/380V distribution network. The principle of this device is based on the photovoltaic technology islanding mechanism and anti-islanding protection strategy

with the anti-islanding function archived by breaking the operation requirement of the islanding scenario. The design principles of three types (resistive

inductive

capacitive) of low voltage anti-islanding devices are studied

and technical data of serialized low voltage anti-islanding devices are calculated with practical engineering experience used for reference. Through the test result

the device principle has been verified and analyzed. By comparing the test results and load characteristics of different types of devices

the conclusion that resistive low voltage anti-islanding device will be a better choice is drawn.
