The DECS-400 is a microprocessor-based controller that provides excitation control, flexible logic control, and optional power system stabilization for synchronous machines in an integrated package. The controller provides an analog output to control the firing of external bridge(s) and monitors machine parameters to control, limit, and protect the synchronous machine from operating beyond its capability limitations.
The optional power system stabilizer function is an IEEE-type PSS2A, dual input, "integral of accelerating power" stabilizer that provides supplementary damping for low-frequency local mode, inter area, and inter unit power system oscillations.
The Power System Stabilizer Model PSS-100 is a two-input, microprocessor-based stabilizer that measures change of speed and change of power to produce the integral of accelerating power. The PSS-100 provides supplementary damping for low frequency power system oscillations ranging from 0.1 to 5.0 Hz, which covers local mode, inter-area mode and inter-unit mode power system oscillations. The isolated ±10 VDC analog output of the PSS-100 is applied into the excitation system summing point to dampen the oscillations.
(6) The RDP-300 Remote Display Panel is a Human-Machine Interface (HMI) used with single or dual DECS-200, DECS-300, or DECS-400 based Digital Excitation Control Systems to provide remote control, to view metered quantities, and to provide annunciation of digital controller status and alarms. The RDP-300 uses a touch-sensitive six inch diagonal monitoring screen with RS-485 Modbus™ communication protocol, which may be located up to 4000 feet away from the DECS-200, DECS-300, or DECS-400 Controller(s).
Basler static exciter systems are custom designed to support a wide range of applications regardless of the prime mover. Our excitation systems will enhance system performance and improve efficiency in new and retrofit applications. We support excitation currents up to 10,000Amps and voltages up to 750Vdc continuous. This makes Basler your complete source for excitation system solutions.
