Basler Electric DECS-100-B15 Digital Excitation Control System (AVR)

Product Brief Description

The Basler Electric DECS-100-B15 is a microprocessor-based digital automatic voltage regulator (AVR) for brushless synchronous generators up to 5MW. It delivers high-precision excitation control, voltage regulation, VAR and power factor management for generators paralleled with the utility grid or other gensets. The rugged potted hardware design offers strong resistance to vibration, humidity and electrical noise for industrial, marine and power generation environments.

Product Functions

• Precise generator terminal voltage regulation with PID adaptive gain control for stable steady-state and transient response
• 7.0Adc continuous PWM excitation output, supporting fast field forcing for load transient conditions
• Multiple control modes: voltage droop, isochronous, VAR control and power factor control for paralleling operation
• Built-in power system stabilizer (PSS) to suppress low-frequency power oscillation on grid-connected generators
• Integrated generator protection: over-excitation, under-excitation, overvoltage, undervoltage and loss of sensing detection
• PC configuration via BESTCOMS software for parameter setup, data logging and real-time monitoring
• Supports 5A CT secondary input, multi-range AC voltage sensing for single-phase or three-phase connections

Application Scenarios

• Industrial backup diesel and gas generator sets for factories, hospitals and data centers
• Small thermal power plants, hydro generators and cogeneration / distributed generation systems
• Utility paralleling, peak shaving and independent island-mode power generation
• Marine vessel and offshore platform synchronous generator excitation control
• Commercial standby power systems and remote site power generation assets
