| Summary: | The main purpose of electric device is to isolate the faulted component from the
healthy part as fast as possible in order to prevent further damage and
endangering human life. The objectives of these studies are to study the overall
generator and generator transformer protection at Kapar Energy Ventures and propose
recommendation to improve the protection setting and coordination (if
required).Generator protection is very important to safe guard the generator at
Kapar Energy Ventures power station. Nevertheless, the auxiliary system to the
generator plays an equally vital role to ensure that the generator continue to
work as intended. There were times that generator and its auxiliary equipment
had tripped due to miscoordinated protection system or wrong settings. A
protection system must satisfy the following requirements
Selective - disconnect the equipment is restricted to the nurumum
necessary to isolate fault.
Sensitivity - sensitive enough to operate under minimum fault condition.
Stable - stable and remain inoperative under certain specific condition .
Fast - fast operation in order to clear the fault from the system and to
minimize damage to the affected component
Reliable - the protective equipment should not fail to operate in the
events of faults in the protected zone. It may be necessary to provide
backup protection to cover the failure the remaining protection |
