초록
In order to evaluate the response of the grid-connected systems, Phase lock technology is widely used in power electronic devices to obtain the phase angle, amplitude, and frequency of the grid voltage because phase locked loop (PLL) algorithms are very important for grid synchronization and monitoring in the grid connected power electronic devices. This paper presents a performance evaluation in tracking grid angular frequency through single phase synchronization techniques which are an enhanced PLL (EPLL), second-order generalized integrator-PLL (SOGI-PLL), and second-order generalized integrator-frequency locked loop (SOGI-FLL). These techniques are properly analyzed through several steps to get the best technique which can track the frequency accurately and smoothly.
