論GDC780BE21 3BHE004468R0021控制器的優(yōu)勢
步驟1(4)退出:當(dāng)三相kvar值小于或等于該設(shè)定點(diǎn)中設(shè)定的值,分配給該步驟的輸出繼電器將斷電。
由于過補(bǔ)償是可能的,所以可以將漏失值設(shè)置為負(fù)VAR。
?步驟1(4)拾取延遲:該步驟將在設(shè)定點(diǎn)中設(shè)置的延遲達(dá)到假設(shè)滿足所有其他條件,則經(jīng)過。
注:該延遲設(shè)置將在系統(tǒng)穩(wěn)定時(shí)間設(shè)置后開始倒計(jì)時(shí)已經(jīng)過去了。
?步驟1(4)禁用時(shí)間:當(dāng)步驟關(guān)閉時(shí),直到此設(shè)定點(diǎn)中設(shè)置的時(shí)間已過。這允許電容器在之前放電再次通電。
?系統(tǒng)穩(wěn)定時(shí)間:執(zhí)行任何動作時(shí)(打開/關(guān)閉步驟或檢測到低電壓),必須允許系統(tǒng)在本中設(shè)置的時(shí)間內(nèi)穩(wěn)定設(shè)置點(diǎn),然后才能執(zhí)行任何進(jìn)一步的操作。這一時(shí)間是必要的系統(tǒng)穩(wěn)定,無需電容器嘗試充電
?低電壓電平
當(dāng)系統(tǒng)電壓(平均三相電壓)時(shí)等于或小于該設(shè)定值時(shí),所有步驟均關(guān)閉。恢復(fù)后(三相電壓大于該設(shè)定點(diǎn))系統(tǒng)中設(shè)定的時(shí)間在執(zhí)行任何動作之前,穩(wěn)定時(shí)間設(shè)定點(diǎn)必須已過。如果不需要此功能,請將其設(shè)置為“關(guān)閉”。
?低電壓檢測延遲:在某些情況下,出現(xiàn)噪聲或尖峰線路可能不希望立即檢測低電壓,因此設(shè)定點(diǎn)可用于延遲檢測,直到電壓確實(shí)較低。
?步進(jìn)優(yōu)先級:步進(jìn)優(yōu)先級設(shè)定點(diǎn)決定了步進(jìn)的順序允許在多個(gè)條件可能滿足的情況下打開步驟。因此,具有最高優(yōu)先級的步驟將首先通電。如果步驟最高優(yōu)先級已通電,第二高優(yōu)先級的步驟將為使用等等。步驟優(yōu)先級從最高到最低(從左到右)設(shè)置為:查看此設(shè)定點(diǎn)。例如,“1,2,3,4”表示步驟1具有最高優(yōu)先級和步驟4具有最低優(yōu)先級。請注意,只允許打開一個(gè)步驟一次打開或關(guān)閉。
A、 1.3實(shí)際值以下消息已添加到PQMII實(shí)際值結(jié)構(gòu)中:適應(yīng)這種修改。消息位于“實(shí)際值”頁面中狀態(tài)?MOD 506實(shí)際值。路徑:實(shí)際值214?A2狀態(tài)214216;MOD 506實(shí)際值
STEP 1(4) DROPOUT: When the three-phase kvar value becomes less than or equal to
the value set in this setpoint the output relay assigned to the STEP will de-energize.
Since over compensation is possible, the dropout value can be set to negative vars.
? STEP 1(4) PICKUP DELAY: The STEP will turn on after the delay set in this setpoint has
elapsed assuming all other conditions have been met.
Note This delay setting will start counting down once the SYSTEM STABILIZATION TIME setting
has elapsed.
? STEP 1(4) DISABLE TIME: When STEP turns off, it is not allowed to turn back on until the
time set in this setpoint has elapsed. This allows the capacitors to discharge before
being re-energized again.
? SYSTEM STABILIZATION TIME: When any action is performed (turning STEPS on/off or
low voltage is detected), the system must be allowed to stabilize for the time set in this
setpoint before any further actions can be performed. This time is necessary to allow
the system to stabilize without the capacitors trying to recharge
? LOW VOLTAGE LEVEL: When the system voltage (average three-phase voltage)
becomes equal to or less than this setpoint, all STEPS are turned off. Upon recovery
(three-phase voltage is greater than this setpoint) the time set in the SYSTEM
STABILIZATION TIME setpoint must have elapsed before any actions will be performed. If
this feature is not required, set it to “Off”.
? LOW VOLTAGE DETECT DELAY: In some cases where noise or spikes are present on
the line it may not be desirable to detect low voltage right away, therefore, this
setpoint can be used to delay the detection until voltage is definitely low.
? STEP PRIORITY: The STEP PRIORITY setpoint determines the sequence the STEPS are
allowed to turn on in a case where the condition may be satisfied by more than one
STEP. Therefore, the STEP with the highest priority will be energized first. If the STEP
with highest priority is already energized, the STEP with second highest priority will be
used, and so forth. The STEP priority is set from highest to lowest (left to right) when
viewing this setpoint. For example, “1,2,3,4” signifies that STEP 1 has the highest
priority and STEP 4 has the lowest priority. Note that only one STEP is allowed to turn
on or off at a time.
