PPM 300 Shaft generator controller

The PPM 300 Shaft generator controller controls and protects the system when a shaft generator is connected, and it controls and protects the shaft generator breaker.

When a shaft generator is connected, it is normally the ship's only power source, but it can run in parallel with the gensets and supply a base load for an extended period (long-time parallel). In such cases, the PPM 300 Shaft generator controller works with the PPM 300 Genset controllers to ensure efficient power management.

A DEIF power management system can include as many Shaft generator controllers as necessary.

Part of the versatile PPM 300 range

The PPM 300 Shaft generator controller is part of the DEIF PPM 300 range of versatile controllers with built-in multi-master power management features. The range offers variants designed for a wide range of marine and offshore applications –from generator control and protection to engineered power management solutions developed for generators, battery energy storage, shore connections, and bus tie breakers. For general information about the PPM 300 range, see the PPM 300 main page.

Highly customisable architecture

All PPM 300 variants can be specified with 4 or 7 I/O module slots. The modules provide voltage and current measurement, I/O, engine control, governor and AVR functions, and communication. Three modules are mandatory, but you can use the remaining 1 or 4 slots to customise the controller by adding modules or leave them empty. In addition, you can add up to 9 expansion racks to a single PPM 300 to get up to 58 free module slots (up to 4 in the base rack and up to 6 in each expansion rack).

Unique ANSI 87G differential protection

With the optional ACM3.2 module, you can add ANSI 87G differential protection for generators. The module measures phase currents on the consumer and neutral sides of a generator in order to detect phase-to-phase faults or phase-to-earth faults in earthed generator systems. With this unique feature, you can design reliable and safe power systems without external differential protection devices.

For a full list of modules, see the Modules tab.

Recommended I/O modules

The table shows a 7-slot rack, but the controller is also available with a 4-slot rack. Modules PSM3.1, ACM3.1, and PCM3.1 are mandatory. If you add expansion module racks, each expansion rack must contain a PSM3.2 power supply module but does not need to contain other modules.
