設定點-功率因數。此設置確定由維護的功率因數調節水平DECS-100。功率因數設定值也可在設置調整屏幕上輸入，設定值選項卡，功率因數控制（PF）-功率因數設定點。功率因數設定值可從-0.6調整至-1
（1） 或以0.001的增量為0.6至+1。當DECS-100為在AVR模式下運行，并調節功率因數設定值。電壓匹配。電壓匹配控件和指示器由兩個按鈕和兩個相鄰按鈕組成指標。單擊“打開”按鈕將相鄰“打開”指示器的顏色更改為綠色，并啟用通過DECS-100進行電壓匹配。當啟用電壓匹配時，DECS-一百將自動調整勵磁電流，使發電機輸出電壓與同步前的母線電壓相匹配。
為了啟用電壓匹配，必須滿足以下條件。
?并聯發電機補償觸點（端子52L和52M）必須短路。
?DECS-100電壓匹配輸入必須短路（端子VM和VMC）。
?必須通過短路端子52J和52K（斷路器開路）禁用Var/PF控制。
?DECS-100必須在AVR模式下運行。
單擊“關閉”按鈕將相鄰“關閉”指示器的顏色更改為紅色，并禁用電壓匹配函數。
控制模式。單擊AVR按鈕將相鄰AVR指示器的顏色更改為綠色，并啟用AVR操作模式。在AVR模式下運行時，DECS-100調節發電機AVR設定點的輸出電壓。單擊FCR按鈕將相鄰FCR指示器的顏色更改為綠色，并啟用FCR操作模式。在FCR模式下運行時，DECS-100將磁場電流保持在FCR設定值。啟用FCR模式將關閉電壓匹配。微調。升高和降低按鈕控制操作設定點的微調。這些按鈕的功能與關閉連接到外部的相應觸點組相同
調整DECS-100的端子（6D和7減少，6U和7增加）。對于AVR模式，每個點擊升高按鈕將電壓設定值增加0.01伏；每次點擊下方按鈕降低電壓設定值0.01伏。微調的最小和最大限制電壓設定值由調節器感應電壓設置（系統配置屏幕）控制以及精細電壓調整-頻帶設置（設置調整屏幕）。微調電壓設定值可以增加/減少，不高于/低于調節器感應電壓設定值加/減頻帶設置。例如，100伏的調節器感測電壓設置和一個頻帶
10%的設置允許微調功能將電壓設定值增加到最大值并將電壓設定點降低到最小90伏。對于Var、PF或FCR模式升高和降低按鈕在整個調整范圍內提供精細調整。
Setpoint - Current (A). This setting defines the field current setpoint when operating in FCR mode. The current setpoint can also be entered at the Setting Adjustments screen, Setpoint tab, Field Current Regulator (FCR) - FCR Setpoint. Current values from 0 to 7 Adc may be entered in increments of 0.01 Adc. The background color of this field is green when operating in FCR mode. Setpoint - Var (% of nom.). This setting determines the level of generator vars maintained by the DECS100 when operating in var mode. The var setpoint can also be entered at the Setting Adjustments screen, Setpoint tab, Reactive Power Control (VAR) - VAR Setpoint (% of nom.). The background color of this field is green when the DECS-100 is operating in AVR mode and is regulating the var setpoint. Setpoint - Power Factor. This setting determines the level of power factor regulation maintained by the DECS-100. The power factor setpoint can also be entered at the Setting Adjustments screen, Setpoint tab, Power Factor Control (PF) - PF Setpoint. Power Factor setpoint values are adjustable from -0.6 to -1 (1) or 0.6 to +1 in 0.001 increments. The background color of this field is green when the DECS-100 is operating in AVR mode and is regulating the power factor setpoint. Voltage Matching. The Voltage Matching controls and indicators consist of two buttons and two adjacent indicators. Clicking the ON button changes the color of the adjacent ON indicator to green and enables voltage matching by the DECS-100. When Voltage Matching is enabled, the DECS-100 automatically adjusts the field current to match the generator output voltage with the bus voltage prior to synchronizing. In order for Voltage Matching to be enabled, the following conditions must be met. ? The Parallel Generator Compensation Contacts (terminals 52L and 52M) must be shorted. ? The DECS-100 Voltage Matching input must be shorted (terminals VM and VMC). ? Var/PF control must be disabled by shorting terminals 52J and 52K (open breaker). ? The DECS-100 must be operating in AVR mode. Clicking the OFF button changes the color of the adjacent OFF indicator to red and disables the voltage matching function. Control Mode. Clicking the AVR button changes the color of the adjacent AVR indicator to green and enables the AVR operating mode. When operating in AVR mode, the DECS-100 regulates the generator output voltage at the AVR setpoint. Clicking the FCR button changes the color of the adjacent FCRindicator to green and enables the FCR operating mode. When operating in FCR mode, the DECS-100 maintains the field current at the FCR setpoint. Enabling the FCR mode turns off Voltage Matching. Fine Adjustment. Raise and Lower buttons control the fine adjustment of the operating setpoint. These buttons perform the same function as closing the appropriate set of contacts connected to the External Adjust terminals (6D and 7 to decrease, 6U and 7 to increase) of the DECS-100. For AVR mode, each click of the Raise button increases the voltage setpoint 0.01 volts; each click of the Lower button decreases the voltage setpoint 0.01 volts. The minimum and maximum limits for fine adjustment of the voltage setpoint are controlled by the Regulator Sensing Voltage setting (System Configuration screen) and the Fine Voltage Adjustment - Band setting (Setting Adjustments screen). Fine adjustment of the voltage setpoint can be increased/decreased no higher/lower than the Regulator Sensing Voltage setting plus/minus the Band setting. For example, a Regulator Sensing Voltage setting of 100 volts and a Band setting of 10 percent allows the Fine Adjustment function to increase the voltage setpoint to a maximum of 110 volts and decrease the voltage setpoint to a minimum of 90 volts. For Var, PF, or FCR modes, the Raise and Lower buttons provide fine adjustment over the entire adjustment range.
