Title: Operating doubly-fed induction generators as virtual synchronous generators
Inventor: QINGCHANG ZHONG
IPC: H02P9/00
Filed: 2016-10-17
Abstract: A doubly-fed induction generator (DFIG) is operated as a grid-friendly virtual synchronous generator (VSG). The DFIG is modelled as a differential gear that links a rotor shaft driven by a prime mover, a virtual stator shaft coupled with a virtual synchronous generator G and a virtual slip shaft coupled with a virtual synchronous motor M. A variable frequency drive behaves as a virtual synchronous motor-generator set to regulate the speed of the virtual synchronous motor M so that the speed of the virtual stator shaft, i.e., the speed of the virtual synchronous generator G, is within a narrow band around the grid frequency even when the rotor shaft speed changes. A grid-connected DFIG may be controlled to behave like a synchronous generator without using a phase-locked loop (PLL). Possible application fields include renewable energy, such as wind energy, wave energy, and aircraft power systems.For wind applications, a DFIG-VSG system is able to provide the kinetic energy stored in the turbine/rotor shaft as inertia to support the grid frequency and provide reactive power to support the grid voltage.
