I. Product Overview

WOODWARD 5460-836 is a high-end specialized controller for steam turbine generators in the 505 series. As an advanced version of 5460-796, it has significantly enhanced grid connection control, load distribution, and multi-machine parallel capabilities, specifically designed for power generation applications that require precise synchronization, stable load carrying, and grid connection, achieving full lifecycle control from startup, synchronization, load carrying to protection. 

II. Core Functional Characteristics

Three-mode Control: Speed control, load control, and isochronous synchronization control, perfectly suitable for single-unit / grid-connected / parallel operation conditions.

Advanced Automatic Synchronization: Built-in microprocessor synchronizer (PWM output), automatically matching frequency, phase, and voltage, achieving one-click grid connection.

Multi-generator Parallel Load Distribution: Supports droop control + isochronous load distribution. Power is evenly distributed when multiple generators are connected in parallel.

Dual Actuator Drive: Independently controls the two valves (main steam valve / regulating valve), suitable for complex steam turbine systems.

Comprehensive Protection: Over-speed, under-speed, vibration, shaft displacement, low oil pressure, high exhaust temperature, reverse power, etc., multiple levels of protection.

Dual Independent Communication: RS-232 + RS-422 dual serial ports, supporting GAP programming, Modbus communication, and DCS access.

Local / Remote Programming: Local operation via LCD panel, or remote configuration, monitoring, and diagnosis via GAP software.

Explosion-proof Certification: Class I, Div 2 certification, suitable for hazardous areas such as petrochemicals.
