| 摘 要： | 在电网发生故障时,及时、准确地检测孤岛效应,对并网发电系统具有重要意义,为解决传统孤岛保护控制存在孤岛检测盲区,使得孤岛保护失效的问题,这里采用了被动检测法与有功功率扰动法相结合的复合检测方法,既减小了孤岛保护控制对输出电能质量的影响,又实现了无盲区的孤岛保护控制。实验结果表明,该方法能够在不同的负载情况下快速、准确地检测出孤岛现象。

| Abstract: | Anti-islanding is one of the key problems for grid-connected power generation system.Non-detection zone disables the conventional islanding protection.In order to solve the problem,a method is adopted in combination with passive protection and active power disturbance protection.This method decreases the effect of electric power quality and realizes the protection of non-detection zone.The experiment results verifies the good performance of the method. |
