Abstract: In situations where there are risks of damage to equipment or to personnel operating equipment, simulators play an important role in training operators. Once the operators develop a certain level of confidence over the simulator they can be further trained on the actual equipment. The paper describes the development of a custom build simulator for synchronising alternators, used to train operators at Yallourn TAFE College in Victoria, Australia.
Synchronising an alternator with another one or with the grid involves running the alternator to be synchronised at a precise speed, adjusting a number of parameters and closing the alternator circuit breaker at a specific time determined by the synchroscope. The process involves a number of tasks to be performed in a given sequence. Failure to close the breaker at the specific instant may cause severe currents to flow in associated circuits and if not properly protected this may cause damage to equipment and to personnel. Even the machine is protected severe torques and vibrations could cause mechanical failure of the machine over a number of years, considerably shortening its lifetime.
Power station and steam operations Group of Yallourn College of TAFE (TAFE stands for Technical and Further Education) runs courses in training operators for power stations. The students learn theory of electricity and obtain part of hands on experience in the laboratories and nearby power stations. The group requested Monash University to develop a computer simulation software package to train students in synchronisation of alternator to the grid. The authors undertook the project and the package was developed.
2. Basic conditions for synchronising alternators and synchronising gear at TAFE
Basic conditions to be satisfied before synchronisation an alternator to a busbar are: Terminal voltage of the alternator (incoming voltage) should be approximately same as the busbar voltage. The difference should be less than 4%.
Incoming frequency and busbar frequency should be the same. Maximum difference should be less than 1%. The incoming supply and busbar supply should be at the same phase position. The machine can handle 8º-phase mismatch between incoming and busbar voltages.
