系统工作状 态说明:

此供电系统 分别有2台变压器并 联供电,正常运行时补偿器接在2#变压器下端 ,1#2#变压器之间 母联断开运行。1#变压器下有 一套SVC运行。我们 生产的补偿器两台控制器检测信号分别接两台变压器的信号。系统正常运行时补偿器由2#控制器控制 。当2# 变压器检修 时,系统合上母联开关,同时断开2#变压器,此 时由1#控制器控制 补偿器。

1CK开关可以选 择PLC的运行状态 ,当开关接通PLCI1.7)点时,补 偿器由1#控制器控制 投切。接通PLCI2.0)点时,补 偿器由2#控制器控制 投切。当I1.5I1.6I1.7I2.04个点都不通 时由PLC检测(I2.1I2.2I2.3)这3个点的状态 自动选择控制状态。I2.1为母联状态 ,I2.21# 变压器接触 器状态,I2.32# 变压器接触 器状态。

 

Instructions for System Operating Mode:

The power supply system consists of two transformers in parallel connection. Under normal operation, the compensator is connected to the lower part of the transformer 2# and the bus between the transformers 1# and 2# is disconnected. A set of SVC is running below the transformer 1#. The detection signals of the two controllers of our compensator are connected to the signals of the two transformers. When the system runs normally, the compensator is controlled by the controller 2#. For overhaul of the transformer 2#, turn on the switch of bus connection and meanwhile disconnect the transformer 2#, and then the transformer 1# is controlled by the compensator.

The operating state of PLC is optional by 1CK switch. When the switch turns on PLC (I1.7), the switching of compensator is controlled by the controller 1#. When the PLC (I2.0) is turned on, the switching of compensator is controlled by the controller 2#. If none of I1.5, I1.6, I1.7 and I2.0, is turned on, PLC examines the three points (I2.1, I2.2 and I2.3) for automatic selection of control state. I2.1 is the state of bus connection, I2.2 is the state of contactor of transformer 1# and I2.3 is the state of contactor of transformer 2#.
