Analysis of a diesel-engine driven generating unit and the possibility for voltage flicker

An example of a diesel generator model with fluctuating engine torque for transient analysis using XTAP

“…Diesel engine is a kind of four-cycle internal combustion engines and the number of cylinders firing in each revolution N F of the shaft is given by where N C is the number of cylinders. As for detail of the deriving the relation, refer to [4] and [5].…”

“…Among the common examples of the number of the poles, 6 and 8 poles are mentioned as the cause of the most sensitive frequencies for human perception in [4]. Therefore, a diesel generator of 6 poles with 12 cylinders is considered in this study.…”

A Diesel Generator Model with Fluctuating Engine Torque Including Magnetic Saturation for Transient Analysis using XTAP

“…Waveform of mechanical torque of diesel engine generator and its possibility for voltage flicker was thoroughly investigated in [4]. It concluded that the misfiring of the diesel engine has caused the flicker in that case study.…”

“…Some example waveforms of the engine torque are also available on [4]. The normalized engine torque for two revolutions shown in the Fig.…”

“…As for detail of the deriving the relation, refer to [4] and [5]. Among the common examples of the number of the poles, 6 and 8 are mentioned as the most sensitive frequencies for human perception in [4].…”
