啟動(dòng)控制-發(fā)電機(jī)軟啟動(dòng)時(shí)間（秒）。該設(shè)置定義發(fā)電機(jī)軟啟動(dòng)的時(shí)間限制
電壓斜坡時(shí)間。軟啟動(dòng)時(shí)間將發(fā)電機(jī)電壓過(guò)沖降至最低，可設(shè)置為1至7200秒，以1秒為增量。

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.
