The Operational Management and Control cross-cutting project encompassed both aspects of traditional power converter and drive systems as well as device, module and converter/drive status monitoring, diagnostics and prognostics.
The work on traditional control aspects concentrated on control for high frequency converters, where the amount of internally stored energy is inherently low, requiring higher control loop bandwidth. The work on status monitoring was primarily aimed at modular converter systems, such as large cellular converter structures used in HVDC systems.
The aim for operational management was to improve the availability of power electronics, either through maintenance scheduled with sufficient advance notice through the use of fault diagnosis techniques, the ability to run a degrading system either at full or part capacity using redundancy or controlled performance reduction, or a combination of the two.
Regarding controls, the aim was to develop hardware and algorithms that ensure a power electronic system exhibits the correct input, internal, and output behaviour in real time, as well as the supervisory functions that allow operational management to occur.
