Market for aerospace electrical systems growing rapidly with the adoption of more electric technologies on new aircraft programmes. Global market is expected to reach $24 Billion by 2017* and will grow even further under the adoption of novel aircraft designs and power generation. While these relate to the civil market, there is likewise opportunity in the space and defence sectors.

and earth faults. The PNDC has an 11kV network composed of overhead lines and underground cables with mock impedances used to provide a representation of typical overhead lines and cable lengths which cannot be achieved within the network compound. The overhead line can be configured as a radial feeder with an equivalent length of 60km which permits to demonstrate a number of voltage issue, e.g. due to unbalance load and distributed generation, and to test and demonstrate solutions.
Technical details
PNDC LV network is powered by its HV circuit via 11/0.4 kV step- down transformers. Cables with mock impedances represent an urban distribution network with long feeder lengths. Single and three phase load banks simulate load profiles required during
EV chargers) while outdoor LV pillars are used to change network topology, isolate parts of the network (e.g. to test generators) or as connection points for equipment placed on (bunded) test bays in the network compound. DAQ points allow remote monitoring and control.
The PNDC’s 11kV network is remotely controlled. Within the PNDC control room the GE PowerOn Fusion system is installed to monitor and control the 11kV network’s modern remote switchable Ring Main Units, Extensible Switch gear and Circuit
the SCADA/DMS system allowing the full vision of the network’s configuration and status, current flows and voltage level.

3kHz enabling high fidelity replication of phenomena such as harmonic distortions. The PNDC has a real-time digital simulation capability based on an RTDS platform which can be operated in two distinct but complementary modes: Controller hardware in the loop: Control and protection devices can be tested in real-time under realistic grid operating conditions simulated in the RTDS. The interface between the device under test and the RTDS is achieved through a number of I/O cards. Power hardware in the loop (work in progress): The physical 11kV network can be extended in simulation through the motor generator set, which acts as an interface. As such, the impact of large grid disturbances and HVDC on distribution networks and microgrids can be tested in a low-risk environment.
