4 Application The PPU anagement (PP) is a standard power management system for marine applications. The system has been designed to carry out generator control, supervision and protection functions of up to 8 generators running in parallel. The PP supports different main systems depending on the individual application. The system performs power management features such as load dependent start/stop, programmable start priority, heavy consumer control, blackout start sequence, supervision of a shore breaker and a bus coupler, symmetrical and asymmetrical load sharing, trip of non-essential load groups and programmable I/Os etc. (the PP system covers the requirements for most simple and medium-sized marine systems). Each unit contains all necessary -phase measuring circuits and presents all values and alarms on the LCD display. Besides the LCD display, the power management unit has an additional operator panel (AOP-2) with 8 pushbuttons and 16 LEDs. The AOP-2 has a CANbus connection to the display unit and can be placed anywhere in the switchboard (max. 200 m from display unit). ultiple AOP-2s can be connected to the CANbus line with parallel operation (X4 option). The AOP-2 enables status information over the system and includes plant mode control. Communication to an external alarm and monitoring system can be done via TCP/IP odbus, or RS485 odbus RTU. Display The display is a separate unit and can be mounted directly on the PP base unit or in the switchboard via the display cable. Up to displays can be connected to the same main unit (X2 option). Diesel generator PPU anagement (PP) anagement The power management functions are handled in a separate 2-bit processor. As default the P processor is placed in DG unit 1. The load dependent start/stop function can be adjusted as predicted available rated power (kw), as predicted available apparent power (KVA) or as percentage rated power (%). The start priority selection can either be handled from the P unit for the entire system or locally via a 1 st priority pushbutton on each display unit. The heavy consumer control is able to be adjusted as fixed load or variable load (e.g. thrusters). The output signal can also be adjusted as either pulse signal or steady signal. If a blackout situation occurs, the operator can define the following functions: - Start one or two diesel generators, - automatically change plant mode to SEI- or mode, and - in case of short circuit to activate one or no start attempts In case of an open bus coupling switch, the system can automatically be forced into switchboard control. This can be indicated at the AOP-2 and additionally at each display unit by a yellow PS control LED. The load dependent stop function can be blocked by either an external input or by a set point. Using the set point will only block the load dependent stop function in case of heavy consumer operation. and frequency control The PPU anagement (PP) can control speed governors/avrs by using relay or analogue output signals. The load sharing function has a separate analogue load share line. This allows placing of additional bus couplers anywhere in the switchboard and ensures active load sharing at open bus coupler positions. The following regulator functions are available: - Active load sharing - Reactive load sharing - Voltage control (option) - PF, VAR control (option) Additional operator panel (AOP-2) SEI- SHAFT S POS.ON FORCED SWBD REQUESTED NEL TRIP BB ALAR TRIPPED SECURED ON PS BLOCKED CONNECTED LD STOP BLOCK DG SHUTDOWN SEI- SHAFT SECURED ON SECURED OFF LAP TEST DEIF A/S Page 4 of 11
