The automatic voltage control for tap changer, parallel control TR8ATCC, if installed, may be

set to operate in Master Follower (MF) mode, or Minimise Circulating Current (MCC) mode. The

commissioning tests for each parallel control mode are addressed separately in the following

procedure.

Secondary injection of load current (I

) and secondary bus voltage (U

) equivalent quantities

are required during installation and commissioning tests. The test consists mainly of:

Increasing or decreasing the injected voltage or current at the analogue inputs of the IED.

Checking that the corresponding commands (Lower or Raise) are issued by the voltage

control function.

Setting confirmation is an important step for voltage control in the installation and

commissioning phase to ensure consistency of power systems base quantities, alarm/

blocking conditions and parallel control settings for each transformer control function.

Before starting any test, verify the following settings in PCM600 or the local HMI for TR1ATCC,

TR8ATCC and TCMYLTC and TCLYLTC.

•

Confirm power system base quantities

I1Base, I2Base, UBase.
