摘要 近年来,随着“双碳”目标的明确提出,分布式光伏发电的投资比重越来越大,此类并网发电系统一旦发生孤岛效应,对整个电力网络的供电质量及电网工作人员的人身安全会带来极大的危害。为此,需对孤岛保护装置的工作原理及作用进行分析与总结,从而合理地应用防孤岛保护装置和反孤岛保护装置,避免此两类装置在分布式光伏发电系统中被电力用户或设计人员混淆功能或误使用,保障光伏发电系统的安全运行。 In recent years,with the clear proposal of the“dual carbon”target,the proportion of investment in distributed photovoltaic power generation is increasing.Once such grid-connected power generation system has an island effect,it will bring great harm to the power supply quality of the entire power network and the person-al safety of the power grid staff.Therefore,it is necessary to analyze and summarize the working principle and function of the islanding protection device,inorder to reasonably apply the anti-island protection device and the anti-islanding protection device,and avoid these two types of devices being confused by power users or design-ers in the distributed photovoltaic power generation system,ensuring the safe operation of the photovoltaic pow-er generation system.
