Woodward EC8551-094FY Synchronizer

Description

The Woodward EC8551-094FY is a microprocessor-based synchronizer designed for use on two or three-phase AC generators. It provides automatic frequency, phase, and voltage matching using either analog or discrete output bias signals. This synchronizer is suitable for a wide range of prime movers and generators, from fast-reacting diesel engines to soft-reacting gas turbines.

Features

• Phase match or slip frequency synchronization with voltage matching
• Two-phase true RMS voltage sensing of generator and bus with Class I accuracy
• Selectable operating modes (Run, Check, Permissive, and Off)
• Synch-Check and synchronization time monitoring
• Dead bus closing of circuit breaker on demand
• Two analog load share lines for load/VAR sharing
• Active power and power factor control in mains parallel operation
• Voltage and frequency control in isolated operation
• Generator real power setpoint by parameter or via 0/4 to 20 mA analog input
• Soft unloading and power limit value with relay output
• Control outputs: Discrete raise/lower for speed and voltage, or analog signals (Voltage, Current, and PWM)
• Single-phase CT sensing for generator with power, overload, voltage, and frequency protection
• Two-line bright liquid crystal display for operation, alarm, measuring values visualization, and parametrization
• Multi-level password protection of parameters
• Woodward ToolKit software for configuration via USB
• Two built-in languages: English and German
