摘要
为了保证微电网从并网向孤岛状态的平稳过渡,通过分析各种孤岛检测技术的检测特性,发现电压相位突变检测技术与被动频率检测技术存在较强的互补性,提出利用二者组合构建孤岛检测技术用于微电网的孤岛检测.并利用Matlab/Simulink进行仿真验证,通过选择有代表性的负载,模拟实际过程,进行相应的分析研究.仿真结果验证了该方法的正确性.
To secure a smooth transition of micro-grids from grid connection to islanding state,detection performances of various islanding detection technologies are examined.The analysis shows that voltage phase jump detection technology and passive frequency detection technology are highly complementary.A new islanding detection technology combining these two technologies is proposed for islanding detection of micro-grids.In Matlab/Simulink environments,typical load models are chosen for simulation and analysis.The results indicate that this technology is effective.
