What components make up the 60 hertz (Hz) EPDC system?

Each of the components listed plays a critical role in an EPDC (Electric Power Distribution Control) system operating at 60 Hz.

The shipping service power generation system is essential as it provides the initial electricity required for operations on the ship. This generation system typically includes various generators that convert mechanical energy into electrical energy to supply power to different ship systems.

The Three Ship Service Gas Turbine Generators (SSGTGs) are specific types of generators that are designed to provide reliable and efficient power. They are a crucial part of the power generation aspect of the ship's operations, ensuring consistent energy availability.

The Ship Service Power Distribution System encompasses the infrastructure needed to distribute generated power throughout the vessel. This system is essential for delivering electricity to various equipment and systems onboard, allowing for the functioning of essential services.

Therefore, since each of these components plays an integral role in the overall functionality of the EPDC system, it follows that all of them are necessary for the system to operate effectively at the specified frequency of 60 Hz.
