Description

Product Brief Introduction

Woodward easYgen 3500-5 is a microprocessor-integrated full-function generator set controller designed for complex multi-grid, multi-bus segment power management applications. It supports standalone backup, mains parallel, peak shaving, cogeneration, and multi-generator fleet synchronous load sharing, coordinating up to 32 generator units across 32 independent bus segments via CANopen network communication with LS-5 breaker synchronizer modules. It integrates complete engine monitoring, generator voltage/frequency regulation, protective interlock, and remote communication functions for prime power, standby, and distributed generation power systems.

Working Principle

PT voltage transformers and CT current transformers transmit generator and mains bus voltage/current analog signals to easYgen 3500-5 analog input circuits for real-time RMS measurement sampling. The internal dual-core microprocessor calculates active/reactive power, frequency, phase angle difference, and compares measured values against user-configured protection setpoints. When mains power deviation or load demand threshold crossing is detected, the controller outputs digital drive signals to engine governor and voltage regulator to adjust generator speed and excitation voltage, executing synchronized breaker closing logic via CANopen LS-5 modules. All operating data, fault alarms, and event timestamps are stored to non-volatile flash memory and transmitted to upper SCADA systems via Ethernet Modbus communication channels.

Applicable Industries

Data center standby power systems, industrial manufacturing microgrid cogeneration, remote mining site prime power, hospital critical life-support backup generation, commercial shopping mall distributed generation, offshore marine vessel power management, solar-wind hybrid diesel backup microgrids, airport uninterruptible power supply plants

Installation Mandatory Requirements

1. Mounting Method: Cabinet embedded panel mounting, maintain minimum 50 mm rear clearance for wiring and natural heat convection
2. Measurement Wiring: Voltage PT secondary circuits must install dedicated short-circuit protective fuses; CT current secondary wiring strictly prohibited from open-circuit operation
3. Power Supply: 12/24 V DC battery power source must connect with reverse polarity protection diode circuit at terminal block
4. CAN Bus Wiring: Use shielded twisted-pair CAN cable, 120 Ω termination resistor installed at both physical bus endpoints
5. Grounding: Controller chassis dedicated protective earth terminal connected to control cabinet PE bus with minimum 2.5 mm² copper cable
6. Cabinet Environment: Install inside IP40+ control cabinet to block conductive dust and water spray exposure

Operation & Maintenance Precautions

1. Calibrate voltage/current measurement inputs every 12 months with precision power analyzer to maintain rated ±1% metering accuracy
2. Never energize CT secondary terminals without closed loop wiring; open-circuit CT generates dangerous high voltage that damages controller analog circuits
3. CAN bus cable total length must not exceed 1000 meters; use signal repeater modules for longer distribution cabinet layouts
4. Ambient operating temperature exceeding +70 °C triggers automatic performance derating and load-sharing instability
5. Backup battery for real-time clock event logging must be replaced every 4 years to prevent timestamp loss during power outages
6. Clear fault log storage memory only after complete on-site maintenance record backup to retain regulatory compliance operational data
