No Interruptions due to Power Failure in Low Voltage Grids
The latest VDE-AR-N 4105: 2018-11 defines the dynamic grid stabilization. The network stability or isolation from the grid must also be secured if any voltage sags or peaks should occur.
Providing the input voltage is within the parameters of the generating unit or voltage storage, system disconnection must not occur in less than 3 seconds.
Equally in the event of any under voltage, coupling switches must remain energized for three seconds to compensate for any power system events such as voltage transients.
As long as the input voltage is within the defined voltage range of the generating unit, or the storage, disconnection from the system grid must not occur.
SOLUTION:
Using the J Schneider, Online Dynamic Grid Stabilization (ODGS) the following generating and storage solutions are comfortably achieved as follows:
Avoidance of under voltage malfunctions, as “ONLINE” capacitor based a UPS system is employed to ensure the operation of coupling switches or contactors. This “Online” system ensures a continuous power supply without any potential interruption due to power failure. The unique and well proven J Schneider, Type AC C-TEC and C-TEC series devices are well acknowledged as the solution.
