'Low Voltage Ride Through(LVRT
) Ability of DFIG based Wind Energy Conversion System I,IEEE
The main challenges are the Low Voltage Ride Through (LVRT
) capability, the reactive power demand during these voltage dips, and the power recovery after the voltage dip.
Concerning the specific LVRT
code which the wind generation system should follow, the Denmark code is selectively used .
Those two fields are connected by the transmission line L5 with a long distance of 200 km to investigate the proposed controller capabilities in a weak power system, which is difficult to guarantee the LVRT
capability of DFIG, especially under sensor fault case.
In an approach similar to the series grid side passive impedance networks, a virtual resistance is introduced in the equivalent rotor circuit using a LVRT
controller to decrease rotor fault currents and its decay time while a virtual inductance increases the leakage inductance of the rotor circuit with similar results.
In order to achieve the above objectives, the microgrid with LVRT
capability was designed.
KENERSYS turbines are designed to meet the new grid code requirements which include the Low Voltage Ride Through (LVRT
It also supports low voltage ride through, or LVRT
, and provides ground fault protection.
Both dynamic grid code and static grid code requirements are regulation of power factor, the operating range of voltage, fault ride-through or low voltage ride through (LVRT
) capability , .
