brushless excitation system UNITROL 1020 3BHE030579R0003

For detailed instructions on commissioning, refer to the User Manual. Commissioning procedure overview:
1. Make sure that all of the connections are correct and safe.
2. Download the configuration file to the AVR. Make sure that the parameters are correct.
3. Examine the digital and analog I/Os in standstill.
4. Do tests with the machine:
a) Standstill
• Measure resistance of exciter stator winding. b) No load condition
• Increase the speed of the machine to nominal.
• Start excitation in Manual mode and increase the manual setpoint until machine voltage is 50%.
• Use CMT 1000 to verify the AVR measurements and compare them with other equipment used, such as protection devices.
• Increase the setpoint until the machine voltage is 100% and tune the AVR with the AVR tuning assistant.
• Do step response tests to examine performance in Manual mode and Auto mode.
c) Machine connected to grid
• Select AUTO (voltage regulator).
• Increase the AUTO setpoint to verify the polarity of the of IM measurement. Q must increase.
d) Do step response tests to examine performance in Auto mode and direct VAR regulator modes.
5. Finalizing commissioning
a) Save the parameters on the AVR and verify the status with CMT 1000.
b) Save backup files for project documentation.
