Thus, a specific installation is used to provide a specific hybrid power supply, hybridized with a conventional grid. For this last case, among the problems, which must be carefully solved, is the synchronization. Indeed, the synchronization consists of implementing a control strategy and electronic control of the interconnection to the grid of this type of energy sources. It is possible to support the power system during an eventual failure, which must take into account various disturbances that may occur on the grid (amplitude variations, phase shift, harmonics, and unbalance load). It is based on a rapid and accurate detection of the phase angle of the power grid voltage, which can be estimated using a locked-down phase (PLL). In this paper, we are interested in several types of PLL then, make a detailed analysis on a type by examining its behavior in normal and special grid faults.
