摘要
随着当前中国新能源的发展,分布式光伏项目犹如雨后春笋般涌现,随之而来的分布式光伏客户的并网安全问题就显得尤为重要。本文研制的一键反孤岛控制器,实现电网侧主线开关、分布式电源并网开关的分合位置实时监测,当判断孤岛形成,远程给台区所有并网开关下分闸命令,阻止孤岛。
With the current development of new energy in China,distributed photovoltaic projects are springing up like bamboo shoots after a spring rain,resulting in distributed photovoltaic customer grid security is particularly important.The one-button anti-islanding controller developed in this paper can realize the real-time monitoring of the opening and closing positions of the main line switch and the grid-connected switch of distributed power supply on the grid side.When the islanding is judged to be formed,all grid-connected switches in the platform area can be remotely issued the opening command to prevent the islanding.
