Harmonic filter with integrated power factor correction

摘要

A distributed electrical power generating and utilizing system includes an induction generator driven by a prime mover requiring reactive power to operate for providing electrical power on a bus. The bus has a gross load and is also connectable to a utility power grid by a switch. The gross load includes at least a non-linear electrical load component, typically including a variable speed device and associated diode rectifier front end. The bus includes a harmonic filter having a power factor-correcting capacitor integrated therewith for collectively compensating harmonic distortion caused by the non-linear load component and for correcting power factor to compensate for reactive power required by at least the inductive generator.
