HONEYWELL SPS5785脈沖模塊
計量、操作和報警通過單擊計量按鈕或單擊可查看計量、操作和報警屏幕菜單欄上的屏幕并單擊計量/操作。計量上顯示的信息,通過在查看屏幕時單擊計量按鈕,或通過以下方式凍結操作和報警屏幕:單擊菜單欄上的測光,然后單擊禁用測光??赏ㄟ^單擊恢復計量按鈕,或單擊菜單欄上的計量并單擊啟用計量。計量,操作和報警屏幕由兩個選項卡組成:操作和報警/狀態(tài)。操作標號操作選項卡計量值、設定值和控制功能如圖5-16所示。發(fā)電機電壓(V)。這些計量值報告了VA-B、VC-B、VCA和VAVG發(fā)電機的狀態(tài)電壓。報告的值是在端子E1、E2和E3處感測到的電壓與發(fā)電機PT比。所有計量值每秒更新一次。當單相感應為使用(系統(tǒng)配置屏幕、感測電壓)和DECS-100感測電壓端子(E1,E2和E3)如圖4-7或4-9所示連接,所有發(fā)電機電壓計量值將是相同的。運行狀態(tài)。操作狀態(tài)控制和指示器包括三個按鈕和三個相應的指標。
操作狀態(tài)按鈕標記為PF、VAR和OFF
單擊PF按鈕將相鄰PF指示器的顏色更改為綠色,并使DECS-100保持期望功率因數(shù)調節(jié)點。功率因數(shù)調節(jié)點可設置在0.6范圍內導致0.6滯后。單擊VAR按鈕將相鄰VAR指示器的顏色更改為綠色,并使DECS-100保持期望的var調節(jié)點。可以設置無功調節(jié)點在100%吸收到100%生成的范圍內。單擊“關閉”按鈕可更改相鄰關閉指示器的顏色為紅色,并禁用功率因數(shù)和無功調節(jié)。工作狀態(tài)控制裝置的操作由跨接觸點的狀態(tài)決定DECS-100 Var/PF控制端子(52J、52K)。當這些觸點打開時,工作狀態(tài)控件已啟用。閉合端子52J和52K處的觸點將禁用工作狀態(tài)控制和中斷VAR或功率因數(shù)的調節(jié),直到觸點再次打開。
設定值-電壓(V)。該設置字段可用于輸入所需的發(fā)電機輸出端子電壓電壓設定值也可以在設置調整屏幕、設定值選項卡、或其他位置輸入,自動電壓調節(jié)器(AVR)-AVR設定點(V)。以下情況下,此字段的背景色為綠色:在AVR模式下運行,功率因數(shù)和無功調節(jié)被禁用。設定值-電流(A)。該設置定義了在FCR模式下運行時的磁場電流設定值。這個電流設定值也可在設置調整屏幕、設定值選項卡、現(xiàn)場電流中輸入調節(jié)器(FCR)-FCR設定點??梢砸?.01的增量輸入0到7 Adc的電流值Adc。在FCR模式下操作時,該字段的背景顏色為綠色。
Operating Status. The Operating Status controls and indicators include three buttons and three corresponding indicators. Operating Status buttons are labeled PF, VAR, and OFF. Clicking the PF button changes the color of the adjacent PF indicator to green and causes the DECS-100 to maintain the desired power factor regulation point. The power factor regulation point can be set within the range of 0.6 lead to 0.6 lag. Clicking the VAR button changes the color of the adjacent VAR indicator to green and causes the DECS-100 to maintain the desired var regulation point. The var regulation point can be set within the range of 100 percent absorb to 100 percent generate. Clicking the OFF button changes the color of the adjacent OFF indicator to red and disables power factor and var regulation. Operation of the Operating Status controls is determined by the status of the contacts connected across the DECS-100 Var/PF Control terminals (52J, 52K). When these contacts are open, the Operating Status controls are enabled. Closing the contacts at terminals 52J and 52K disables the Operating Status controls and interrupts regulation of vars or power factor until the contacts are opened again. Setpoint - Voltage (V). This setting field can be used to enter the desired generator output terminal voltage. The voltage setpoint can also be entered at the Setting Adjustments screen, Setpoint tab, Automatic Voltage Regulator (AVR) - AVR Setpoint (V). The background color of this field is green when operating in AVR mode and power factor and var regulation is disabled. 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.
