發(fā)電機(jī)過電壓——報(bào)警延時(shí)（秒）。此設(shè)置確定了發(fā)電機(jī)過電壓條件必須在DECS-100通知該條件之前存在。
Reactive Power Step Response - Decrement of VAR Setpoint (%). This field indicates the decrease that occurs to the FCR setpoint when the corresponding Decrement button is clicked. The "Decrease VAR Setpoint =" field is used to set and indicate the percentage that the var setpoint is decreased to when the Decrement button is clicked. Any setpoint value (expressed as a percent of nominal) within range or lower than the existing setpoint value can be typed into the "Decrease VAR Setpoint =" field. The var setpoint changes to the new value when the adjacent button is clicked. Clicking this button sends the var setpoint value to the DECS-100 and changes the color of the pushbutton from gray to red. Reactive Power Step Response - Meter Value. These fields and the dial pointer indicate the value of the selected var setpoint. When the var setpoint is changed by clicking the increment, decrement, or setpoint button, the meter value fields and dial pointer indicate the setpoint value. A new var setpoint, expressed as a kvar value or a percentage of nominal, can be typed directly into either Meter Value field or selected by dragging the dial pointer to the desired value. The new value is sent to the DECS-100 by clicking the Send button. Reactive Power Step Response - Current Setpoint (%). The active var setpoint (adjusted by using any of the previously mentioned methods) is displayed in this field. To return the var setpoint to the nominal setting, the button adjacent to the "VAR Setpoint (%) (Nominal)" field should be clicked. If the VAR tab is left to view other tabs or screens without returning the VAR setpoint to nominal, a var setpoint dialog box appears. Clicking the Yes button returns the var setpoint to nominal. Clicking No maintains the var setpoint at the current value. Protection Settings The Protection Settings screen consists of two tabs: Protection and Limiter. Click the Protection button to access the Protection Settings screen or click Screens on the menu bar and click Protection Settings. Protection Tab Protection settings are shown in Figure 5-14 and are described in the following paragraphs. Generator Overvoltage - Voltage Level (%). The value of this field is expressed as a percentage of the nominal generator voltage and determines the level of generator voltage required to initiate a generator overvoltage condition. An overvoltage percentage value of 100 to 120 percent may be entered in 1 percent increments. A generator overvoltage condition lights the Generator Overvoltage LED on the front panel. Generator Overvoltage – Alarm Time Delay (sec). This setting establishes the length of time that a generator overvoltage condition must exist before the DECS-100 annunciates the condition.
