DEIF PPM 300 Ship Power Generation Management Controller

The system supports automatic network configuration (using static IPv6), and the controller automatically recognizes and synchronizes parameters and I/O configuration after connecting to the network. The date and time are automatically synchronized through NTP, greatly simplifying debugging work.

Flexible Communication Capability

Network redundancy: The controller forms a ring network through the DEIF network, and any disconnection at any point does not affect communication.

Multi protocol support: Built in 5 RJ45 ports, supporting display unit connection, PC tool (PICUS) access, Modbus TCP communication. Simultaneously supporting communication between CAN bus and engine ECU (electronic control unit), following the universal J1939 protocol to read engine data.

Network security: Supports IPv6/IPv4 dual stack, with authentication mechanism to prevent unauthorized devices from interfering with the network.

Powerful Logic Programming Tool Customs Logic

For applications that require customized logic, PPM 300 provides a user-friendly logic configuration tool, CustomizaLogic. Each controller can define up to 20 input events and 20 output commands; Support communication between controllers, up to 16 input/16 output interactions; Up to 20 signals can also be connected via Modbus. This enables the system to flexibly adapt to various special working conditions, such as overload inquiries, special interlocks, etc.

Accurate communication measurement

The controller can directly measure the three-phase voltage up to 690V AC with an accuracy of 0.5 level. The measurement module has an average filtering function (200ms and 800ms optional), which can smooth out instantaneous fluctuations for display, trend recording, and Modbus transmission, while protection and adjustment values still use instantaneous values to ensure fast response.

Advanced Circuit Breaker Control

Supports multiple types of circuit breakers (pulse type, compact type, continuous type), with automatic synchronous closing, synchronous detection, and load shedding functions. The operator can also manually initiate synchronization or load shedding operations. The position detection and disconnection alarm of circuit breakers ensure the reliability of status monitoring.

Engine Interface and Safe Shutdown

The EIM3.1 module can be used as a safety shutdown module. Even if communication with the main processor card is interrupted, EIM3.1 can independently control the engine to enter a safe shutdown program, achieving a fail safe mode.

Detailed explanation of power management function

The core value of PPM 300 lies in its powerful power management algorithm, which can intelligently dispatch units and ensure the stability and economic operation of the power grid.

Load Sharing and Asymmetric Allocation

The system achieves real-time sharing of active power (kW) and reactive power (kvar) among multiple units through the DEIF network. In addition to traditional symmetric allocation, PPM 300 introduces asymmetric load distribution functionality. For example, in a hybrid system, the shaft generator bears the base load, while the diesel generator shares the remaining fluctuating load; When a unit reaches its asymmetric allocation limit, the system can automatically start the next unit and always maintain the allocation within the set range.

Overload Management

Before starting large equipment such as side thrusters and winches, PPM 300 will conduct a heavy load inquiry. Each controller can manage up to 4 fixed or variable heavy-duty devices, starting in a preset order and with a delay to avoid the impact of high-power device startup on the power grid.

Load related Unit Start Stop

Automatically increase or decrease the number of parallel units based on the current load rate, so that the operating units are always in the high-efficiency range. The system provides two independent parameters that can be used for decision-making on increasing and decreasing units, and supports priority rotation based on operating hours to balance unit wear.

Advanced Anti Blackout Startup and Recovery

PPM 300 has a built-in anti black startup strategy. During critical operations, it is allowed for the busbar to operate in a closed state. If a certain unit's governor or AVR fails, the system will immediately trip the busbar, isolate the faulty unit, and prevent the entire power grid from being affected. Meanwhile, the black start recovery process can be configured to ensure a quick and orderly restoration of power supply after a power loss.

Busbar segmentation management

For complex power distribution systems, PPM 300 supports dividing the busbar into multiple logical segments, and each segment can independently set power management rules. Each controller can control up to 4 external circuit breakers (busbars or shore switches), supporting complex topologies such as ring busbars.

Comprehensive protection function

PPM 300 integrates comprehensive electrical protection, covering generator, busbar, and system level anomalies, and is labeled with corresponding ANSI codes for engineers to understand.
