中文摘要:
      以单相馈能型电子负载为研究对象,详细分析了Sandia频移式孤岛检测法(SFS)原理,描述其检测盲区,并对SFS算法中的参数进行优化。与此同时,将SFS与Sandia电压偏移法(SVS)结合,并辅助过/欠频率、过/欠电压保护,形成一种复合型的孤岛检测法。最后在MATLAB/Simulink环境下,搭建了仿真模型,仿真结果表明,参数优化后,系统可实现特定负载下的无盲区检测,将SFS和SVS结合使用明显提高检测效率,能够快速有效地进行孤岛保护,输出电能质量较高,验证了设计方案的可行性和优越性。
英文摘要:
      The object studied is single phase feedback type electronic load, the principle of Sandia frequency shift islanding detection(SFS) is analyzed in detail, non detection zones are evaluated, and optimizing parameters of SFS algorithm. Meanwhile, SFS and Sandia voltage shift method (SVS) are combined to form a complex of islanding detection method with passive methods of over/under frequency and over/under voltage. Finally, the model of simulation are conducted in with the help of MATLAB/Simulink. The simulation results indicate that the system can be conducted without non detection zones under special loads. The combination with SFS and SVS will significantly improve the detection efficiency,and it can carry islanding protection quickly and efficiently, and power quality is higher, the feasibility and the superiority of the scheme are verified.
