2.1.1 Overall description
The PPM 300 Protection and Power Management controller is a highly configurable controller designed for marine use. It includes a
wide range of control, protection and supervision functions. Applications range from simple genset control and protection, to fully
integrated and engineered power management solutions, developed for fuel-efficient operation. Each controller contains all the
functions that are needed to protect and control a diesel generator, an emergency diesel generator, a shaft generator, a shore
connection, or a bus tie breaker. You can connect up to 32 controllers to create one integrated system solution for standard
applications.
The controllers' power management system controls the system and ensures that it operates optimally. It ensures that the power
required is always available and takes preventative actions to ensure a reliable power supply. Up to 64 heavy consumers can be
configured in the system.
The PPM 300 controllers work together as a true multi-master system. This means that each controller functions as a master
controller. If a controller fails, the remaining controllers continue to function. Redundant communication between the controllers is
possible. If a communication link fails, the system continues to function.
The controller display unit has push-buttons for the operator to close and open the breaker. For gensets, the operator can start and
stop the genset, and change the controller mode and priority. The colour graphic screen shows status and info messages. It also
allows fast access to live data, and alarm management. With the right authorisation, the operator can also check and/or change the
input/output and parameter configuration.
Each controller includes processors and high-speed internal communication. This provides fast protection functions and includes
built-in redundancy.
The controller design is modular, and hardware modules may be replaced or added in the field.
PICUS is a proprietary, free PC software interface to the controller. The designer can use PICUS to create a single-line diagram for
the system, and configure the inputs, outputs and parameters for all the controllers in the system. PICUS also offers system
emulation, supervision, and management of permissions, backups and firmware updates.
