| description | To deal with low-voltage ride-through (LVRT) and to enhance the transient performance of a grid-connected
wind-driven permanent-magnet synchronous generator during voltage dips on the grid side, this study presents
a revised control structure for wind-power converters, comprising a machine-side converter (MSC) and
grid-side converter (GSC). In the proposed approach, the control variables’ references are modified
with grid voltage, and the revised control designs for the MSC and GSC are established. During voltage
dips, the captured wind power is stored as the kinetic energy of the turbine rotor. The active component
of the stator current is curtailed according to the dip level by terminating the maximum power tracking
operation. The modified GSC current references assist the grid in providing the required reactive current
and attempt to minimize the power loss by utilizing the maximum GSC current-carrying capacity. The revised
controls are responsible not only for maintaining the DC-link voltage and GSC current within safe limits,
but also support the grid in providing reactive power during voltage recovery. Simulations verify the
suitability and effectiveness of the proposed design in handling LVRT operations and providing additional
flexibility by incorporating stability and security constraints. |
