A practical guide to understanding how motor-starting loads affect genset performance
Today’s standby power loads are more complex than ever before. In many industrial and commercial applications, standby gensets must supply power to a mixture of linear and nonlinear loads in addition to large motor loads that cycle on and off. Of all the diverse loads a standby genset must supply, applications with motors present the most sizing issues. The dynamic interactions of motors and gensets – along with the impact of motor starters, system inertia, motor loading, frequency dip, genset preload and nonlinear loading – make manual genset sizing difficult, if not impossible.
