Układ regulacji jednofazowego przekształtnika fotowoltaicznego ze zmodyfikowanym generatorem kwadraturowym

Control System of a Single-Phase Photovoltaic Converter with Modified Quadrature Generator

dr inż. Tomasz BINKOWSKI; mgr inż. MAREK NOWAK

Abstract

Control of a photovoltaic converter connected to a single-phase grid requires synchronization with the fundamental component of the voltage. This is performed by the Park transformation of the measured voltage to a rotating orthogonal xy frame. This transformation in single-phase systems requires quadrature signals. The paper proposes that a quadrature generator replace the standard second-order generalized integrator

Streszczenie

Sterowanie przekształtnikiem fotowoltaicznym podłączonym do jednofazowej sieci wymaga synchronizacji z składową podstawową napięcia. Odbywa się to poprzez transformację zmierzonego napięcia do wirującego, ortogonalnego układu współrzędnych. Transformacja ta w układach jednofazowych wykorzystuje sygnały kwadraturowe. W pracy zaproponowano generator kwadraturowy zastępujący standardowo stosowany uogólniony integrator drugiego rzędu.

Keywords

quadrature generator, photovoltaic converter, control.

Słowa kluczowe
