Woodward 8440 - 1923 A Generator Set Controller

Multi-language Support: Configurable with 10 different languages, including English, German, Spanish, French, Italian, Portuguese, Japanese, Chinese, Russian, Turkish, etc.

Flexible Output: Equipped with flexible outputs that can control voltage and speed deviation outputs. These outputs are freely configurable and usually used in conjunction with voltage regulators and speed governors.

Analog Inputs: Provides PWM, current, and voltage analog inputs, typically used for voltage and speed biasing. The output signals of the multi-functional controller can be changed through external jumpers and configurations.

Frequency/Voltage Control: Has configurable frequency/voltage control functions, allowing manual control of the circuit breaker within the controller, and also features reactive power regulation function, which occurs at the grid exchange point.

Load Management: Offers load management functions such as emergency power supply, standby power generation, and automatic base load.

Communication Capability: Supports RS-485 Modbus communication and RS-232 Modbus communication, enabling communication with factory management systems, as well as with toolkit configuration and visualization software.

Operating Environment: Operates in a temperature range of -40℃ to +60℃, adapting to extreme environments, and can withstand ambient humidity up to 95% (non-condensing).

Parameter Monitoring: Utilizes true RMS voltage and current sensing technology to conduct real-time monitoring of the voltage and current of generators, busbars, and mains electricity, reducing sensitivity to harmonics and accurately obtaining electrical parameters. Meanwhile, it monitors the generator speed through magnetic or switch-type speed sensor inputs to determine if there is overspeed or underspeed.

Control and Regulation: Adopts advanced PID control algorithms. Based on the monitored parameters, it compares them with the set values and controls the voltage regulator and speed governor through flexible output ports to adjust the generator's voltage and speed. For example, when the load increases, causing voltage or frequency to drop, the controller will automatically adjust to restore the voltage and frequency to the set values, ensuring stable output. In the case of parallel operation of multiple generator sets, it can realize automatic synchronization function. By controlling phase matching, positive and negative slip frequency, etc., it enables stable parallel operation between generator sets and performs active and reactive load distribution according to settings, allowing proportional load sharing among up to 32 generator sets.

Logic Control: With the integrated Logics Manager? programmable logic function, it can perform various controls on the generator set according to preset logic and conditions, such as automatic start and stop, and automatic switching in case of mains failure, without the need for additional PLC control. It can also be easily integrated with SCADA or PLC-based control systems.

Communication Interaction: Supports CAN network communication, enabling communication with the engine ECU and complying with the standard SAE-J1939 protocol and multiple proprietary engine OEM protocols. At the same time, through serial Modbus RTU (slave) communication, it can conduct data interaction with the SCADA system to realize remote monitoring and external control. It can also connect with the RP-3000 remote panel through the CANopen protocol for remote configuration and control.

Emergency Backup Power Supply: Suitable for places such as data centers, hospitals, commercial and industrial facilities. In the event of a mains power outage, it can automatically start the generator set, quickly restore power supply, and ensure the normal operation of key equipment.

Distributed Generation: Can be used as a utility dispatchable power source to respond to peak demand, increase power supply during peak electricity usage, and ease grid pressure.

Islanded Main Power Supply: Commonly used in oil and gas exploration sites, ships, remote villages, as well as rental or mobile power generation equipment, providing independent power supply for isolated electricity-using places.

Microgrid: In microgrid projects such as military bases, government agencies, zero-carbon communities, and universities, it can realize parallel operation and load management of multiple generator sets, work in coordination with other distributed energy sources, and ensure stable power supply for the microgrid.

Mains Parallel Operation: Used in mains parallel scenarios, it can realize peak shaving and valley filling, adjust the output of the generator set according to grid demand, reduce reliance on mains electricity, and lower electricity costs.

Cogeneration: In places such as sewage treatment plants and biogas production facilities, it can cooperate with cogeneration systems to control the generator set, realize comprehensive utilization of energy, and improve energy efficiency.

Switchgear Upgrade: Can be used for upgrading existing switchgear, adding load sharing and parallel functions to generator control, and enhancing the performance and reliability of the switchgear.
