SECTION 7
TROUBLE SHOOTING
Under normal circumstances the operation of the PFC3 is fully
automatic and once commissioned the unit should continue to
operate without further attention. Should the system fail in
service, the troubleshooting chart shown in Fig 14 will be helpful
in identifying the cause.
Mains Utility Supply Voltage Variations
In some areas, large voltage variations can take place causing
malfunction of the generator control system.
As stated in section 3.2, it is the responsibility of the Generating
et Assembler to install adequate protection to safeguard the
generator.
If satisfactory operation cannot be achieved then is would be
advisable to carry out a Mains Utility Supply Voltage survey over
a minimum period of 24 hours, recording the absolute maximum
and minimum RMS voltages and also the largest step change.
Consult the factory for advice.
The user is reminded of the following information relating to the
paralleling of generators.
• The active power output (kW) of the set is controlled entirely
by the engine governor and NOT by the generator AVR.
Problems concerning kW fluctuations etc. are almost
certainly to do with the engine fuel system and/or frequency
control.
•
The reactive power output (kVAr) of the set is controlled
entirely by the excitation system of the generator (i.e the
AVR). Problems concerning reactive current (circulation/
fluctuation etc.) are almost certainly to do with the generator
AVR and its associated equipment.
