UNDERSTANDING NONLINEAR LOADS AND GENERATOR SETINTERACTIONGregory M. Williams, Inc.(309) 578-4995INTRODUCTIONMany electrical power applications require continuous andhigh quality power. Standby diesel-electric generatingsets are integral parts of the genset sizing requires an UNDERSTANDING of thegenset characteristics and the connected load . Nonlinearloads, including; uninterruptable power supply (UPS),variable frequency drives (VFD), adjustable speed drives(ASD), and switched mode power supplies, present a specialchallenge to successful delivery of high quality powerunder all operating conditions. UNDERSTANDING how thisequipment interacts is sets are inherently a high reactance sourcecompared to a LOADS , not generators , cause should be sized for NONLINEAR LOADS to reduceheating and voltage waveform distortion.
6 in Figure 5. It is the result of high frequency resonance occurring in the rectifier source circuit due to inherent inductance and capacitance in the circuit elements.
