Abstract:

Precise calculation of the grid voltage magnitude and phase is required for the operation of distributed power generation (DPG) systems. While the general concepts involved in the synchronization of single-phase and three-phase systems are the same, the practical implementation can differ substantially, the single-phase case being more challenging. Phase-locked-loop (PLL) based methods have been widely used for the synchronization of single-phase systems. These methods can be roughly grouped into methods that use a quadrature signal generator (QSG) and methods that implement a single-phase PLL. One drawback of single-phase PLL methods is that they usually produce a component at twice the fundamental frequency that needs to be removed. On the contrary, QSG methods do not induce such component, enabling therefore the use of three-phase PLLs. On the other hand, the phase error usually depends on the input magnitude for both methods. This paper proposes a QSG based single-phase synchronization technique that overcomes the aforementioned limitations of both single-phase PLLs and QSGs. It will be shown that the proposed method accurately estimates the magnitude and phase of the microgrid/grid fundamental voltage with high dynamic response, even under high distorted conditions
