无功功率阶跃响应-VAR设定值的减少(%)。该字段表示减少单击相应的减量按钮时,FCR设定点发生。“减少VARSetpoint=“字段用于设置和指示当单击减量按钮。范围内或更低的任何设定点值(表示为标称值的百分比)可以在“减少VAR设定值”字段中输入现有设定值。var设定点单击相邻按钮时更改为新值。点击该按钮发送var设定值值设置为DECS-100,并将按钮的颜色从灰色更改为红色。
无功功率阶跃响应-仪表值。这些字段和拨号指针指示选择的var设定点。当通过单击增量、减量或设定点更改var设定点时按钮,仪表值字段和刻度盘指针指示设定值。新的var设定点,表示为作为kvar值或标称百分比,可直接输入仪表值字段或选择通过将拨号指针拖动到所需值。新值通过单击发送到DECS-100发送按钮。
无功功率阶跃响应-电流设定点(%)。有功var设定值(通过使用以下任一项进行调整:前面提到的方法)显示在该字段中。将var设定值返回至标称值设置时,应点击“VAR设定点(%)(标称)”字段旁边的按钮。如果VAR选项卡为左键可查看其他选项卡或屏幕,无需将VAR设定点返回至标称值,VAR设定值对话框出现。单击“是”按钮将var设定值返回至标称值。单击“否”将维护var当前值的设定点。
保护设置
保护设置屏幕由两个选项卡组成:保护和限制器。单击“保护”按钮以访问保护设置屏幕,或单击菜单栏上的屏幕,然后单击保护设置。
保护标签保护设置如图5-14所示,并在以下段落中描述。
发电机过电压-电压电平(%)。该字段的值表示为标称发电机电压,确定启动发电机所需的发电机电压水平过电压条件。可在1中输入100%至120%的过电压百分比值
增量百分比。发电机过电压状态点亮前部的发电机过电压LED面板
发电机过电压——报警延时(秒)。此设置确定了发电机过电压条件必须在DECS-100通知该条件之前存在。
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.
