DEIF PPM 300 Shaft generator controller

Customisable shaft generator controller designed for efficient power management

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.
