Modular Marine Electrical Power Distribution Application, with SCADA (AEL-MEPD-01)
PL-178830
The Modular Marine Electrical Power Distribution Application, “AEL-MEPD-01”, has been specifically designed by EDIBON to offer complete theoretical and practical training in marine power generation and electrical distribution systems. This training system addresses essential topics such as marine switchboard configuration, onboard power generation, propulsion control, uninterruptible power supplies (UPS), critical and non-critical circuits, and generator synchronization—either within an isolated marine grid or while connected to shore power.
The onboard power generation system features two motor-generator sets, each with independent control, monitoring, and protection modules to safeguard against various electrical faults. These generators support both voltage and frequency regulation or power output adjustment, depending on the selected operational mode. The system operates in either grid-forming or grid-following mode, with automatic mode selection based on the status of all circuit breakers.
The marine switchboard distribution setup includes multiple circuit breakers arranged in a ring-type configuration with two main busbars and three interconnection branches. To avoid incorrect synchronization, the breakers have safety locking mechanisms that activate when voltage is detected at their terminals. Additionally, four synchronization switches manage the connection of different power sources by comparing phase angles before engagement.
The propulsion system, connected to the main electrical bus, consists of two propeller systems powered by variable frequency drives. Using the integrated SCADA software, students can simulate and analyze real-world parameters involved in marine propulsion for mid-sized vessels, such as ship speed, thrust, torque, advance coefficient (based on the Wageningen series), and total resistance forces.
A critical feature of the “AEL-MEPD-01” is the simulation of blackout recovery. If both main power generators fail, the integrated UPS system enables the study of emergency power recovery procedures and ensures continuity of vital onboard services and loads.
The “AEL-MEPD-01” includes a full-featured SCADA Control and Data Acquisition System to supervise and operate the complete electrical system. It accurately replicates a full shipboard power infrastructure, including the Navigation Bridge, onboard power generation units, distribution switchboard, propulsion controls, and ship load management panels. To simulate dynamic onboard energy usage, students can draw a power consumption curve in real-time by varying active load parameters.
