Product Overview
The WOODWARD 8200-1302 is a sophisticated control solution belonging to the EasyGen-3000 series, specifically engineered for mission-critical power generation applications. This versatile controller integrates generator set control, protection, and logic functions into a single, compact unit. It is designed to manage the synchronization and load sharing of multiple generator sets operating in parallel, either in island mode or in conjunction with a utility grid.
Designed with user flexibility in mind, the 8200-1302 supports a wide range of prime mover types, including diesel and gas engines. Its modular architecture allows it to handle complex control logic via internal programming blocks, reducing the need for external PLCs. By providing comprehensive monitoring of electrical and mechanical parameters, this controller ensures optimal performance and longevity of the power generation assets.
Core Capabilities
The 8200-1302 excels in applications requiring high reliability and seamless integration. It manages the entire lifecycle of a generator set, from automatic startup and synchronization to load acceptance and shutdown.
Advanced Control Features
Automatic Mains Failure (AMF): The controller continuously monitors the utility mains voltage and frequency. In the event of a mains failure, it automatically initiates the startup sequence of the generator set and connects the load.
Multi-Set Paralleling: Capable of controlling up to 32 generator sets in parallel, the unit manages the complexities of load sharing and frequency control across the entire power plant without requiring an external load sharing module.
Process Control Logic: Features a programmable logic environment (based on IEC 61131-3) that allows engineers to create custom control strategies, interlocks, and sequences directly within the controller.
Digital Voltage Regulation (DVR): Optionally supports automatic voltage regulation (AVR) communication to precisely control generator output voltage and reactive power (kVAR) sharing.
Integrated PTC Inputs: Includes dedicated inputs for monitoring winding temperatures, ensuring the generator is protected against thermal overload.
Graphic LCD Display: A high-contrast backlit display provides real-time status visualization, alarms, and parameter measurements, facilitating easy on-site diagnostics.

Protection & Synchronization Details
Safety and equipment protection are paramount in the design of the WOODWARD 8200-1302. The controller includes a comprehensive array of protective functions that are fully customizable. These include protections against over/under voltage, over/under frequency, reverse power, overcurrent, and short circuits. The protection logic is designed to separate the generator set from the bus immediately upon detection of a fault condition, preventing damage to the alternator or the prime mover.
The synchronization process is managed with high precision. The controller closes the circuit breaker when the voltage, frequency, and phase angle of the generator match the bus within user-defined limits (dead bus, live bus, or mains return). For load sharing, the 8200-1302 utilizes a high-speed CAN communication link or analog lines to balance the active power (kW) and reactive power (kVAR) among connected units. This ensures that no single generator is overloaded, promoting even wear and tear across the fleet.
User Interface and Connectivity
The front panel of the 8200-1302 is designed for ease of use in varying lighting conditions. The four-line graphical LCD display allows operators to navigate through menus, view real-time electrical parameters (volts, amps, Hz, power factor), and acknowledge alarms. Password protection levels are available to prevent unauthorized modification of critical setpoints.
Connectivity is a strong suit of this model. It features multiple communication ports, allowing seamless integration into SCADA systems and Building Management Systems (BMS) via Modbus RTU or TCP/IP. The CAN bus interface facilitates direct communication with electronic engines (ECUs), enabling the controller to read engine parameters such as coolant temperature, oil pressure, and fuel status, thereby eliminating the need for additional sensor wiring.
Applications
The versatility of the WOODWARD 8200-1302 makes it suitable for a wide range of industrial and commercial power applications. It is the controller of choice for data centers, hospitals, airports, and manufacturing plants where uninterruptible power is critical. Its ability to manage complex synchronization makes it ideal for cogeneration (CHP) plants, peak shaving installations, and complex island-mode microgrids. By providing reliable, automated control, the 8200-1302 ensures that standby power systems are always ready to assume load instantly when required.
