摘　　要：针对Sandia频移(SFS)法不适合高品质因数负载的应用场合且会造成正弦电流畸变的缺点,采用基于SFS与Sandia压移(SVS)的混合式孤岛检测新方法,研究了SFS法斩波量算式的改进及SFS法与SVS法混合使用的问题。所提出的新方法提高了孤岛检测性能,并降低了电流的畸变率。所以,基于SFS与SVS的混合式孤岛检测法,能够克服传统SFS法的缺点,既可以提高孤岛检测成功率,又可以改善DG系统的供电品质。In response to the disadvantage that SFS method is not suitable for applications with high-quality factor loads and can cause sinusoidal current distortion,a new hybrid islanding detection method based on SFS and SVS was adopted.The improvement of the chopping formula of SFS method and the problem of mixed use of SFS method and SVS method were studied.With the proposed new method,the performance of islanding detection was improved and the distortion rate of current was reduced.Therefore,the hybrid islanding detection method based on SFS and SVS can overcome the shortcomings of traditional SFS method,improve the success rate of islanding detection,and also improve the power supply quality of DG systems.
