Figure 66. PSS Screen, Output Limiter Tab
Logic Output Limiter – Upper Limit. This per-unit setting adjusts the high limit value for the logic output
limiter. An upper limit of 0.01 to 0.04 may be entered in 0.001 increments.
Logic Output Limiter – Lower Limit. This per-unit setting adjusts the low limit value for the logic output
limiter. A lower limit of –0.4 to –0.01 may be entered in 0.001 increments.
Logic Output Limiter – Time Delay. This setting adjusts the time delay of the logic output limiter. A time
delay of 0 to 2 seconds may be entered in 0.01 second increments.
Metering
The Metering screen consists of four tabs: Operation, System Alarms, System Status, and I/O Status.
Click the Meter button on the tool bar to view the Metering screen.
Operation
The Operation tab of the Metering screen is shown in Figure 67. Operation tab parameters and controls
are described in the following paragraphs.
Generator. Nine real-time metering values display the generator voltage, current and frequency.
Field. Four real-time metering values display the field voltage, current, temperature, and exciter diode
ripple.
Phase Angle. These five real-time metering fields consist of two phase-angle fields for voltage and three
phase-angle fields for current.
Power. Four real-time metering values display generator apparent power, real power, reactive power, and
power factor.
PSS (Power System Stabilizer). Seven real-time values metered by the PSS function display positive
sequence voltage and current, negative sequence voltage and current, terminal frequency deviation,
compensated frequency deviation, the per-unit PSS output level, and PSS rate of change. The PSS
function on/off status is also reported.
Control. These three real-time metering fields display the remote setpoint control signal level (volts or
milliamperes) applied to the auxiliary input terminals and the excitation setpoint control signal level (volts
or milliamperes) being supplied by the DECS-400.
