Report on standardised grid design
(si apre in una nuova finestra)
D6.1: Report on standardised grid design - Interim, finalThe optimal design following OCDA specifications of the STEESMAT on-board DC grid is established. According to these specifications, DC grid architectures are defined by the concept of DC sectors, a group of DC devices that are directly connected to one another in terms of power flow and are switched and protected as one unit by a Smart Breaker. DC sectors for the STEESMAT system will be identified and their role and connection with other sectors defined.

D4.2: Report on model system draft -finalDevelopment of power unit modules and a configurable system-level simulation model of sufficient fidelity in Python. Development of load emulation module (e.g. ship load from realistic ship operation). Computation of power flow, power losses, energy and fuel consumption, and emissions. Verification/validation. In addition to the report, the task aims at delivering a journal paper [PUBLIC] on the simulation model design/development.

D2.2: Report MVDC/LVDC converter - Design, prototype, finalDevelopment, assembly, test, and validation of the 1MW MVDC/LVDC converter. The converter acts as the backbone of the proposed SST and transforming 5kV input voltage to 800V output voltage. The report also documents the development and assessment of a dedicated controller that will later be integrated into the hardware.
Report on AC compatibility in DC grid
(si apre in una nuova finestra)
D6.3: Report on AC compatibility in DC grid -finalThe aim is to determine the maximum permissible AC voltage component that potentially might occur in the STEESMAT on-board DC grid (e.g., caused by switching frequency currents). This component must be limited to avoid premature aging of capacitors. This maximum permissible AC voltage component should be regarded as the upper limit of what the devices must be able to continuously sustain. This task will also approach the electromagnetic interference, i.e., conducted and radiated interference in the on-board DC grids. Since no binding limits on the electromagnetic interference exist for DC grids particularly for marine and industrial sectors, existing limits and measurement methods will be borrowed and adapted from low-voltage AC grids (e.g., IEC 61000-6-4, EN 55011) and other DC networks (e.g., photovoltaic systems). It will be identified which DC components within the STEESMAT system represent critical elements from the electromagneticcompatibility and for which the rules must be applied
