Abstract

This paper briefly discusses the challenges related to the Islanding operation in power systems and presents different methods to detect the islanding condition with an example of photovoltaic applications. Furthermore, it proposes a secure method of islanding detection using synchrophasors. The proposed algorithm has been verified with Real Time Digital Simulator (RTDS) tests, as well as in laboratory environment with an inverter connected to grid. With the help of extensive testing, it is demonstrated that the proposed method successfully performs automatic and manual decisions to assure the correct and secure operation of the distribution grid.

孤岛检测与相量测量单元
本文简要讨论了与电力系统孤岛运行相关的挑战,并以光伏应用为例介绍了孤岛状态检测的不同方法。在此基础上,提出了一种利用同步相量进行孤岛检测的安全方法。该算法已通过实时数字模拟器(RTDS)测试以及逆变器并网的实验室环境进行了验证。通过大量的测试表明,该方法成功地实现了自动决策和人工决策,保证了配电网的正确安全运行。
