IS200AEPCH1BAA燃机电气卡件
设置调整屏幕由两个选项卡组成：设置点和启动。
设定点选项卡
设置调整屏幕的设置点选项卡设置如图5-7所示
设定点选项卡在以下段落中描述。
自动电压调节器（AVR）-AVR设定点（V）。此设置字段用于输入所需的发电机输出端电压。AVR设定值范围取决于调节器感应电压和频带设置。
精细电压调整-频带设置（%）。波段设置确定最小值和最大值允许对AVR设定点进行调整（以调节器感应电压设置的百分比表示）（参见图5-8））。频带设置值输入为调节器感应电压设置的百分比以0.1%的增量在0至15%的范围内。
下降-设定点（%）。此设置控制DECS-100的无功下垂补偿功能。
设定点值确定发电机电压设定点中允许的变化量
DECS-100响应无功负载。设定点值可从0%调整到10%，增量为0.01%. 设定点基于0.8功率因数负载。无功功率控制（VAR）-VAR设定点（额定值的%）。VAR设定值决定了在Var控制模式下运行时，DECS-100维持发电机Var。值从-100到+可以在VAR设定点字段中输入100%，增量为1.0%。
功率因数控制（PF）-PF设定点。
PF设定点决定发电机功率因数的水平
在功率因数控制模式下运行时由DECS-100维护。PF设定值为：可从-0.6调整至-1（1）或0.6至+1，增量为0.001。启动选项卡
设置调整屏幕的启动选项卡设置如图5-8所示“启动”选项卡在以下段落中描述。
启动控制-发电机软启动时间（秒）。该设置定义发电机软启动的时间限制
电压斜坡时间。软启动时间将发电机电压过冲降至最低，可设置为1至7200秒，以1秒为增量。
欠频设置-转角频率（Hz）。转角频率设置定义了使DECS-100调整电压设定点的频率，以使发电机电压如下：选定的伏特/赫兹斜率。在0.01中，可在此设置字段中输入40至65赫兹的值增量。
欠频设置-斜率（伏特/赫兹）。选择发电机低频保护的斜率
具有该每单位设置。可以以0.01的增量输入0到3.00的坡度设置。
电压匹配-速度（秒）。此设置决定发电机电压的调整速度
DECS-100与总线电压匹配。速度设置可在0.01内从1秒调整到300秒增量。
电压匹配-通过触点禁用
此设置选择用于禁用的DECS-100触点输入电压匹配。选择“52JK或52LM”允许52JK和52LM触点输入禁用电压匹配。选择“52JK”仅允许52JK触点输入禁用电压匹配。
电压匹配–模式。电压匹配模式可以保持或恢复。何时维护选择后，DECS-100设定点即使在发电机或公用事业之后仍保持在总线电压水平断路器打开。当选择Revert（恢复）时，DECS-100设定点将恢复到其原始水平
发电机或公用设施断路器断开。
Reactive Power Control (VAR) - VAR Setpoint (% of rated). The VAR Setpoint determines the level of generator vars maintained by the DECS-100 when operating in Var Control mode. Values from -100 to +100 percent in 1.0 percent increments may be entered in the VAR Setpoint field. Power Factor Control (PF) - PF Setpoint. The PF Setpoint determines the level of generator power factor maintained by the DECS-100 when operating in Power Factor Control mode. PF Setpoint values are adjustable from -0.6 to -1 (1) or 0.6 to +1 in 0.001 increments. Startup Tab The Startup-tab settings of the Setting Adjustment screen are shown in Figure 5-8. Each setting of the Startup tab is described in the following paragraphs. Startup Control - Gen Soft Start Time (sec). This setting defines the time limit for the generator soft-start voltage ramp time. The soft-start time minimizes generator voltage overshoot and can be set from 1 to 7,200 seconds in 1 second increments. Underfrequency Setting - Corner Frequency (Hz). The Corner Frequency setting defines the value of frequency that causes the DECS-100 to adjust the voltage setpoint so that the generator voltage follows the selected volts per hertz slope. A value of 40 to 65 hertz can be entered in this setting field in 0.01 increments. Underfrequency Setting - Slope (Volts/Hz). The slope for generator underfrequency protection is selected with this per-unit setting. A slope setting of 0 to 3.00 can be entered in increments of 0.01. Voltage Matching - Speed (sec). This setting determines how quickly the generator voltage is adjusted by the DECS-100 to match the bus voltage. The Speed setting is adjustable from 1 to 300 seconds in 0.01 increments. Voltage Matching – Disable by Contact. This setting selects the DECS-100 contact input used to disable voltage matching. Selecting “52JK or 52LM” allows either the 52JK or 52LM contact input to disable voltage matching. Selecting “52JK” allows only the 52JK contact input to disable voltage matching. Voltage Matching – Mode. The voltage matching mode can be Maintain or Revert. When Maintain is selected, the DECS-100 setpoint is maintained at the bus voltage level even after the generator or utility breaker opens. When Revert is selected, the DECS-100 setpoint reverts to its original level when the generator or utility breaker opens.
