FAQ
1. What is the main function of the Woodward DECS-100-B15?
The DECS-100-B15 is a digital automatic voltage regulator designed to control the excitation system of synchronous generators. It continuously monitors generator voltage and adjusts the excitation output to maintain the required terminal voltage under changing load conditions. The B15 configuration also provides VAR and power factor control functions.
2. What is the voltage regulation accuracy of the DECS-100-B15?
The DECS-100-B15 provides voltage regulation accuracy of approximately ±0.25% from no load to full load under specified operating conditions. Actual system performance can also be affected by generator characteristics, sensing accuracy, excitation system response, and control parameter settings.
3. What operating power supply does the DECS-100-B15 require?
The regulator accepts an operating power input of 88–250 VAC and can operate from single-phase or three-phase sources at 50–400 Hz. The input supply must be correctly selected and wired according to the generator excitation system design.
4. What excitation output can the DECS-100-B15 provide?
The regulator provides a continuous excitation output of 63 VDC at 7 A. It can also provide a boost output of up to 135 VDC at 15 A for 10 seconds. These output capabilities allow the regulator to respond to excitation requirements during normal operation and transient conditions.
5. What control modes are available on the DECS-100-B15?
The DECS-100-B15 supports Automatic Voltage Regulation (AVR), Field Current Regulation (FCR), VAR control, and Power Factor (PF) control. AVR mode maintains generator terminal voltage, while FCR provides manual field-current control. VAR and PF modes are used for reactive power and power factor management in parallel-generation applications.
6. What protection functions are included in the DECS-100-B15?
The DECS-100-B15 includes protection functions such as overvoltage, undervoltage, overexcitation, underexcitation, and loss-of-sensing protection. These functions help prevent abnormal excitation conditions from causing unstable generator operation or damage to the excitation system.
7. How can the DECS-100-B15 be configured and monitored?
The regulator provides an RS-232 communication interface and can be configured and monitored using Woodward/Basler BESTCOMS™ software. Configuration can include voltage regulation, stability, excitation limits, sensing parameters, VAR/PF settings, and other operating parameters. Correct parameter settings should be verified before placing the generator into service.
8. What should be checked if the DECS-100-B15 cannot regulate generator voltage correctly?
Start by checking the operating power supply, generator voltage sensing connections, sensing range selection, and excitation output circuit. Then verify the AVR mode, voltage reference, stability settings, and excitation limits. If voltage sensing is lost or incorrect, the regulator may enter a protective condition. The generator excitation components, wiring, and associated CT/PT circuits should also be inspected before replacing the AVR.
