Voltage control TR1ATCC, TR8ATCC, TCMYLTC, TCLYLTC

Prepare the IED for verification of settings as outlined in section
for test" in this chapter.
The automatic voltage control for tap changer, single control TR1ATCC (90) is based on a transformer
configuration that consists of one tap changer on a single two-winding power transformer.
The automatic voltage control for tap changer, parallel control TR8ATCC (90), 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
during installation and commissioning tests. The test consists mainly of:
1. Increasing or decreasing the injected voltage or current at the analogue inputs of the IED.
2. 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 (90),
TR8ATCC (90) and TCMYLTC (84) and TCLYLTC (84).
• Confirm power system base quantities I1Base, I2Base, V Base.

2.2.4 The command response for the command to move to the current is changed by
selecting the parameter PosDependent. This action decides if it is allowed. The
response if allowed is now successful.
2.2.5 SXCBR & SXSWI: Execution outputs follow the operation request inputs. If not
blocked, output is maintained active until operation request input is deactivated.
Changes are valid for all 2.2 releases.
