Simulations were run in Power System Computer Aided Design and Electromagnetic Transient Including DC (PSCAD/EMTDC) and results using the new T-type converter topology were compared with scenarios where the wind generator was protected by conventional crowbar, DC-chopper and parallel interleaved of the 2-level converters for the rotor and grid side converters of the DFIG.
This paper presents a new alternative T-type multilevel VSC topology for the grid side converter of the DFIG.
Based on the results, an adapted control scheme, considering the control strategies currently available, is proposed for the grid side converter of the doubly fed induction generators to improve power quality.
The currents were in both cases measured on the grid-side of the turbine transformer (i.e., at the connection point from the turbine to the medium-voltage collection grid), during a period of several weeks.
Since the cells are illuminated from the grid side, the optimisation of the grid design is a trade-off between area coverage and conductivity of the grid lines.
Currently, there are several organizations that carry out the smart grid user interface standardization work, including traditional Technical Committee (TC) of the grid side (IEC-TC57 WG21), and TC of the user side (BACnet, KNX).
This paper presents a novel design procedure for the coordinated tuning of rotor side converter (RSC) and grid side converter (GSC) controllers of doubly fed induction generator (DFIG) wind turbine system.
Diversifying the role of renewable energy sources (RES) and in particular, the role of the grid side converter (GSC) has gained a lot of attention recently.
Under the control of the series converter, the neutral current of the grid side iSN is equal to zero. 1) Mathematical model of parallel converter .
Nevertheless, in the event of grid side fault or voltage dip, wind farms often simply trip to protect the wind turbines [6, 7].
