DECS-100操作特性以下段落描述了每個DECS-100操作特性。
模式DECS-100提供多達四種可通過BESTCOMS軟件選擇的操作模式。自動電壓調(diào)節(jié)模式和手動模式是標準功能。無功功率因數(shù)模式是一種選擇。
自動電壓調(diào)節(jié)模式
在自動電壓調(diào)節(jié)（AVR）模式下，DECS-100調(diào)節(jié)rms發(fā)電機輸出電壓。這是通過感應發(fā)電機輸出電壓和調(diào)整直流輸出勵磁電流來實現(xiàn)的將電壓保持在調(diào)節(jié)設定值。調(diào)節(jié)設定點通過升高和降低觸點輸入、附件輸入或通過BESTCOMS軟件進行調(diào)整。調(diào)節(jié)點也可以是：在某些條件下由下垂函數(shù)或低頻函數(shù)修改。
手動模式
在手動模式下，也稱為磁場電流調(diào)節(jié)（FCR）模式，DECS-100維持直流設定水平的勵磁電流。電流電平設定值可在0.1 Adc中從0到7 Adc進行調(diào)整通過升高和降低觸點輸入、可選附件輸入或通過BESTCOMS遞增
軟件在Var控制模式下，DECS-100在以下情況下將發(fā)電機Var（伏安、無功）保持在設定水平與無限總線并聯(lián)。DECS-100通過使用感測的發(fā)電機計算發(fā)電機VAR輸出電壓和電流量。然后調(diào)整直流勵磁電流，以將VAR保持在設定點。Var控制通過BESTCOMS軟件啟用和禁用。當軟件打開時接通時，通過var/功率因數(shù)控制（52J/K）觸點輸入電路啟用或禁用var控制。
var設定值可通過提升和調(diào)節(jié)
從100%吸收到100%發(fā)電低觸點輸入、可選附件輸入或通過BESTCOMS軟件。
功率因數(shù)控制模式（可選）
在功率因數(shù)控制模式下，DECS-100在以下情況下將發(fā)電機功率因數(shù)保持在設定水平與無限總線并聯(lián)。DECS-100使用感測的數(shù)據(jù)計算發(fā)電機功率因數(shù)發(fā)電機輸出電壓和電流量，然后調(diào)整直流勵磁電流以維持設定點的功率因數(shù)。功率因數(shù)控制通過BESTCOMS軟件啟用或禁用。當軟件打開時，通過Var/功率因數(shù)控制（52J/K）啟用或禁用接觸輸入電路。功率因數(shù)設定值可在0.6滯后和0.6超前之間調(diào)整升高和降低觸點輸入、可選附件輸入或通過BESTCOMS軟件。
Front Panel Indicators
Eight front-panel LED indicators light to indicate various protective functions and operating modes.
Section 2, Human-Machine Interface provides more information about the front panel indicators.
Relay Output
A common alarm output contact is provided through terminals AL1 and AL2. This normally open, form A
contact annunciates alarm or trip conditions. The relay output is non-latching.
DECS-100 OPERATING FEATURES
The following paragraphs describe the characteristics of each DECS-100 operating feature.
Operating Modes
The DECS-100 provides up to four modes of operation selectable through BESTCOMS software.
Automatic voltage regulation mode and Manual mode are standard features. Var and Power Factor
modes are an option.
Automatic Voltage Regulation Mode
In Automatic Voltage Regulation (AVR) mode, the DECS-100 regulates rms generator output voltage.
This is accomplished by sensing generator output voltage and adjusting dc output excitation current to
maintain voltage at the regulation setpoint. The regulation setpoint is adjusted by the Raise and Lower contact inputs, the Accessory input, or through BESTCOMS software. The regulation point may also be
modified by the Droop function or the Underfrequency function under certain conditions.
Manual Mode
In Manual mode, also known as Field Current Regulation (FCR) mode, the DECS-100 maintains dc
excitation current at a set level. The current-level setpoint is adjustable from 0 to 7 Adc in 0.1 Adc
increments by the Raise and Lower contact inputs, the optional Accessory input, or through BESTCOMS
software. In Var Control mode, the DECS-100 maintains generator vars (volt-amperes, reactive) at a set level when
paralleling with an infinite bus. The DECS-100 calculates generator vars by using the sensed generator
output voltage and current quantities. It then adjusts the dc excitation current to maintain vars at the
setpoint. Var control is enabled and disabled through BESTCOMS software. When the software is turned
on, var control is enabled or disabled through the Var/Power Factor Control (52J/K) contact input circuit.
The var setpoint is adjustable from 100 percent absorb to 100 percent generate through the Raise and
Lower contact inputs, the optional Accessory input, or through BESTCOMS software.
Power Factor Control Mode (Optional)
In Power Factor Control mode, the DECS-100 maintains generator power factor at a set level when
paralleling with an infinite bus. The DECS-100 calculates generator power factor using the sensed
generator output voltage and current quantities and then adjusts the dc excitation current to maintain
power factor at the setpoint. Power factor control is enabled or disabled through BESTCOMS software.
When the software is turned on, it is enabled or disabled through the Var/Power Factor Control (52J/K)
contact input circuit. The power factor setpoint is adjustable between 0.6 lag and 0.6 lead through the
Raise and Lower contact inputs, the optional Accessory input, or through BESTCOMS software.
