MW-scale power hardware-in-the-loop experiments of rapid power transfers in MVDC naval shipboard power systems

Analysis of experimental rapid power transfer and fault performance in DC naval power systems

“…While this work has demonstrated the gain in speed of fault current interruption by virtue of inhibiting the gating the SCRs of the generator rectifier based on DC side measurements, a more comprehensive investigation is required to develop a system wide fault management approach. Additional work by several of the authors on fault current limited MVDC systems can be found in [15] , [21] - [23].…”

“…The goal was to explore limits posed by the power electronic interfaces which connect loads to the MVDC bus. Data presented in [21] showed experimentally that with existing MVDC equipment such ramp rates can reach ~625 MW/s at 5 kVdc. Moreover, the experiments presented in [17] and [21] showed that transitions of power between different loads can be controlled so well that the prime mover exhibits no disturbance at all.…”

“…Like all other labs at FSU-CAPS the MVDC lab is fully compatible with the PHIL and CHIL concept which allows for the utmost flexible and efficient implementation of different system architectures on the corresponding real-time simulators (in this case RTDS and OPAL-RT). A detailed description of the new MVDC facility along with additional experimental results can be found in [20], [21].…”
