Basler DECS-300 Digital Excitation Control System

Product Brief Description

The Basler DECS-300 is a high-performance microprocessor-based digital excitation controller for synchronous generators. It supports redundant master/standby operation and bumpless transfer, built for medium and large generator applications requiring stable, precise excitation regulation in harsh power plant environments.

Product Features & Functions

• Four control modes: AVR, Field Current Regulation, Power Factor, and Reactive Power control
• Dual programmable PID stability groups and dual preset setpoints per mode
• Bumpless auto-tracking between internal modes and dual redundant DECS-300 units
• Full protective limits: OEL, UEL, stator current limiting, volts/hertz and underfrequency protection
• Adjustable soft start ramp and generator voltage buildup control
• Multi-phase voltage and field current/voltage measurement for high accuracy
• Programmable analog I/O: 4-20mA, 0-10V, ±10V signals for remote control
• Local LCD display + BESTCOMS software for configuration, monitoring and troubleshooting

Application Scenarios

• Medium & large synchronous generators in thermal power plants
