Low Voltage Ride Through Enhancement Based on Improved Direct Power Control of DFIG under Unbalanced and Harmonically Distorted Grid Voltage
In the conventional structure of the wind turbines along with the doubly-fed induction generator (DFIG), the stator is directly connected to the power grid. Therefore, voltage changes in the grid result in severe transient conditions in the stator and rotor. In cases where the changes are severe, the generator will be disconnected from the grid and consequently the grid stability will be attenu...
متن کاملFast Coordinated Control of DFIG Wind Turbine Generators for Low and High Voltage Ride-Through
This paper presents a fast coordinated control scheme of the rotor side converter (RSC), the Direct Current (DC) chopper and the grid side converter (GSC) of doubly fed induction generator (DFIG) wind turbine generators (WTGs) to improve the low voltage ride through (LVRT) and high voltage ride through (HVRT) capability of the DFIG WTGs. The characteristics of DFIG WTGs under voltage sags and s...
متن کاملLow Voltage Ride-Through Capability Improvement of Doubly Fed Induction Generator using DVR and SMES
Abstract: With the growth of communities and the increasing need for electricity, and because of the many benefits of renewable energy sources, the wind turbine has become a completely commercial and inevitable process, with increasing penetration into the electricity grid. Distribution networks, on the other hand, are subject to fault that cause power fluctuations and outflow of wind units. In...
متن کاملEfficient low-voltage ride-through nonlinear backstepping control strategy for PMSG-based wind turbine during the grid faults
This paper presents a new nonlinear backstepping controller for a direct-driven permanent magnet synchronous generator-based wind turbine, which is connected to the power system via back-to-back converters. The proposed controller deals with maximum power point tracking (MPPT) in normal condition and enhances the low-voltage ride-through (LVRT) capability in fault conditions. In this method, to...
متن کاملLow Voltage Ride-through Scheme of the PMSG Wind Power System Based on Coordinated Instantaneous Active Power Control
Abstract: Fast control DC-link voltage is the key to enhance Low-Voltage Ride-Through (LVRT) for the Permanent Magnet Synchronous Generator (PMSG). When grid voltage dips deeply, by the constraint of the capacity of the grid-side converter and reactive power support by the grid-code required, the active power capacity of the grid-side converter will be reduced. Therefore, it cannot stabilize th...
