Abstract
ABSTRACT:For the grid fault under distorted voltage conditions such as symmetrical and unsymmetrical voltage dips, the normal grid voltage synchronization speed is slow. And the longer the transition detection time is, the more dangerous power electronic equipment operation is.For the synchronization of power grid voltage under distorted voltage conditions, this paper proposes a fast and harmonics-insensitive grid voltage synchronization method. Complex finite impulse response filters are used toseparate the fundamental components and main harmonic components. Two adaptive Kalman filters are used to obtain the fundamental components. The simulation and experimental results show that the method mentioned in this paper has the advantages on the rapidity, accuracy, flexibility, stability and so on.关键词
