The University anticipates that the supplied goods will conform to the below requirements:
3. The power supply unit shall be rated at 1MW and is capable of bi-directional power flow at the full power rating.
4. The supply to the unit shall be 50Hz, 415V AC, three phase, neutral and earth.
5. The unit shall supply the following DC outputs:
a. Unipolar: 0 – 1.5kV (floating), 667A
b. Unipolar: 0 – 3kV, 333A
c. Bipolar: 0 – +/-1.5kV, 333A
6. The unit shall be modular and capable of supplying at least ten pieces of equipment under test (e.g. inverters, batteries) simultaneously at the channel’s fully rated power at 1.5kVdc.
7. The unit shall have the following external user control modes:
a. Aurora protocol from a real-time digital simulator (RTDS).
b. Proprietary software for setting DC supply output and running output profile scripts such as ramps, PV array simulation, battery simulation.
c. +/-10V set points.
