Auto Reclosure controlled LVRT
In case that the
LVRT should be able to ride through auto reclosures, the parameter »ARControlledLVRT« has to be set
to »
active«.
In order to supervise the Low Voltage Ride Through events during reclosure, the user has to set the supervision timer
»tLVRT
« at least equal or greater than the complete Multi-Shot AR-runtime. In addition to that the number of permitted
LVRTs has to be set which is usually the number of auto reclosure attempts. The actual LVRT supervision will be
controlled to ride through the preset
LVRT voltage pattern. By reaching the preset number of LVRT events
»
NumberOfLVRT«, the actual LVRT supervision assumes that the detected system fault is permanent, ignores the
voltage profile and issues a tripping command instantaneously in order to disconnect the distributed resource from the
electrical power system.
