Grid-Demonstrator Typ GDC2I55

The Voltage Detecting Systems CAPDIS, IKI-Fault Indicators and IKI-Feeder Control Units are today fixed components of intelligent distribution grid stations for monitoring grid stability and for digital grid operation management. The grid demonstrators are used to simulate distribution grid conditions and faults as well as digital grid operation management in order to learn how to use the devices and integrate them into the distribution grid.

With the grid demonstrator, the function of a control panel with CAPDIS and IKI in a distribution grid station can be demonstrated very clearly. Different grid states as well as different types of faults can be simulated easily. In addition, distribution network sections can be simulated by interconnecting further grid demonstrators.The following functions can be simulated:

• directional load flow simulation (resistive and capacitive)
• directional short circuit detection (2-/ 3- pole)
• directional earth short-circuit detection in the network with low-impedance star point grounding
• directional earth short-circuit detection in the network with isolated star point grounding (transient and static)
• directional double earth short-circuit detection
• directional earth short-circuit detection in the network with inductively grounded star point (transient and static)
• Communication via network interface via IEC-104 and MQTT
• Parameterization/firmware update via the network interface
• Modbus communication and remote switching of the load switch via Modbus
