Features:
- Digital Excitation Control for Synchronous Generator and Motor Applications
- Combines Capability of Voltage/Var/PF Regulation with Integrated Generator Protection
- Operates in Conjunction with Synchronous Generators and Synchronous Motors
The DECS-250 DECS-250-LN1SN1N operates as a complete digital excitation control system, providing precise regulation and exceptional system response for synchronous machines. It continuously performs true RMS sensing of single-phase or three-phase voltage and current, and distributes control signals through integrated I/O to support steady state operation of generator excitation systems. Seamless mode transfer is standard with the DECS-250, however using an optional power system stabilizer will help meet stringent grid code compliance requirements in the event of dynamic stability challenges. The DECS-250 has made improvements in several areas over previous excitation control designs in addition to incorporating auto tuning capability with two PID stability groups.
The DECS-250 provides essential control functions common to the entire excitation system, and is a critical component of the generator protection path, directly affecting the proper, normal operation of the overall synchronous machine. One DECS-250 unit is required per generator depending on the desired control configuration. The DECS-250 occupies a compact package and delivers total functionality in a cost effective, easy-to-use format.
For Enhanced System Stability applications, the DECS-250 DECS-250-LN1SN1N supports optional integrated power system stabilizer (PSS) per IEEE Std. 421.5 type PSS2A/2B/2C. In addition to standard voltage regulation operation, the PSS configuration also performs automatic damping control. The DECS-250 dual stability group configuration executes tuning using the auto tuning feature specified in the control options. Using this method, the power system stabilizer continually monitors the grid frequency oscillations. If the system detects that the generator is experiencing unstable oscillations (outside configured damping levels), it will automatically apply stabilizing signals to the excitation system and maintain grid code compliance.
The DECS-250 DECS-250-LN1SN1N Basler Electric Digital Excitation Control System may still be available for purchase and support from authorized distributors with conformal coating applied to certain internal circuitry for additional protection and reliability.
