To test power electronic models in a real live environment with real voltages and currents a P‑HIL System is required. It simulates your model in real time and generates real voltages and currents with a power from kW up to MW and from DC up to 10kHz or more. EGSTON offers you the perfect solution for these test requirements.
COMPISO P‑HIL System
A COMPISO system unit is a customer specific turn-key P‑HIL solution built out of standard block sets. It is connected to a 50 or 60 Hz low voltage supply grid. Bidirectional grid converters are available from 50 kVA up to 1 MVA. A grid transformer provides galvanic isolation. Groups of 3 to 6 COMPISO digital amplifiers are connected to the DC-BUS. Voltage and current is measured at every amplifier output terminal.
All measurements are available in the HIL real-time processor as inputs for the simulation models. The amplifiers are represented as voltage or current source in the HIL architecture. The HIL drives the amplifiers via high speed fibre optic link. The user can implement its individual real-time model in the HIL. To guarantee a save operation between the HIL and the amplifiers a high speed low latency SFP Interface is provided.
The interface is supported by the HIL platforms:
• National Instruments
Additionally analogue inputs and outputs are provided to connect HILs that do not support the high speed SFP interface.
• Renewable energy grid emulation
• House Emulation
• 12 pulse rectifier
