论GDC780BE21 3BHE004468R0021控制器的优势
步骤1(4)退出:当三相kvar值小于或等于该设定点中设定的值,分配给该步骤的输出继电器将断电。
由于过补偿是可能的,所以可以将漏失值设置为负VAR。
•步骤1(4)拾取延迟:该步骤将在设定点中设置的延迟达到假设满足所有其他条件,则经过。
注:该延迟设置将在系统稳定时间设置后开始倒计时已经过去了。
•步骤1(4)禁用时间:当步骤关闭时,直到此设定点中设置的时间已过。这允许电容器在之前放电再次通电。
•系统稳定时间:执行任何动作时(打开/关闭步骤或检测到低电压),必须允许系统在本中设置的时间内稳定设置点,然后才能执行任何进一步的操作。这一时间是必要的系统稳定,无需电容器尝试充电
•低电压电平
当系统电压(平均三相电压)时等于或小于该设定值时,所有步骤均关闭。恢复后(三相电压大于该设定点)系统中设定的时间在执行任何动作之前,稳定时间设定点必须已过。如果不需要此功能,请将其设置为“关闭”。
•低电压检测延迟:在某些情况下,出现噪声或尖峰线路可能不希望立即检测低电压,因此设定点可用于延迟检测,直到电压确实较低。
•步进优先级:步进优先级设定点决定了步进的顺序允许在多个条件可能满足的情况下打开步骤。因此,具有最高优先级的步骤将首先通电。如果步骤最高优先级已通电,第二高优先级的步骤将为使用等等。步骤优先级从最高到最低(从左到右)设置为:查看此设定点。例如,“1,2,3,4”表示步骤1具有最高优先级和步骤4具有最低优先级。请注意,只允许打开一个步骤一次打开或关闭。
A、 1.3实际值以下消息已添加到PQMII实际值结构中:适应这种修改。消息位于“实际值”页面中状态ØMOD 506实际值。路径:实际值214ØA2状态214216;MOD 506实际值
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.
