Using the sequencing functionality of the EGCP‐3. the control is configured to

start an additional unit two seconds after the load on the master unit exceeds 75%.

When the load reduces to below 30%, the slave unit is removed from the system after 60 seconds.

The controls needs to be able to trade master/slave relationships,

so a switch is used to place one control in Auto and Run w/ Load (Master)

and the second unit in Auto (Slave). Both controls have the option to operate in either

mode—so if sequencing needs to be avoided, the operator can place both

controls in Auto and Run w/ Load, and both units will share the entire electrical load.

The closed transition to shore power was solved by sending a remote fault input to the EGCP‐3 when the

shore power breaker is closed onto the system. When coming into port, ship’s power is reduced before

synchronizing to shore power. This means that only one unit is online with low load. When shore power is

connected, the operator adjusts a switch from “Generators” to “Shore” power. Instigating this switch turns

on the SPM‐D and allows the unit to begin sending digital signals to the EGCP‐3 LS to synchronize the

ship’s power to shore power.

When the breaker is closed, the aux feedback is sent to a remote input on the EGCP‐3 that opens the

generator breaker and shuts the generator down. The system is then completely supplied by shore power.

When the ship switches back to Generators, the remote input is cleared and the unit coming online

synchronizes to the shore power, closes its breaker, and the shore power breaker is immediately opened.

The system is then on Generator power.
