PPM 300 GENSET CONTROLLER

Protection & power management (software/unit)
DEIF’s PPM-3 is a market-leading Power Management System (PMS) standard suitable for a broad range of marine applications with up to 16 diesel generators, two shaft generators, two shore connections, eight bus tie breakers and two emergency/harbour generators including bus tie breaker control and the possibility of wrapped busbar applications.

Each Genset controller can control up to four heavy consumers and connect up to three non-essential load groups.

PPM 300 Genset controller

The PPM 300 Genset controller controls and protects a diesel genset and its generator breaker. Power management features supported by the Genset controller include load-dependent start and stop and may include setting genset priority order, managing heavy consumers, and, if necessary, tripping non-essential loads.
Each Genset controller can control up to four heavy consumers and connect up to three non-essential load groups.

The PPM 300 Genset 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.

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).

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.

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.
