Electrical power systems having reactive power and harmonic support components

Abstract:

An electrical power system connectable to a power grid includes a cluster of electrical power subsystems, each of the electrical power subsystems including a power converter electrically coupled to a generator having a generator rotor and a generator stator. Each of the electrical power subsystems defines a stator power path and a converter power path for providing power to the power grid. Each of the electrical power subsystems further includes a transformer. The system further includes a subsystem breaker configured with each of the electrical power subsystems, and a cluster power path extending from each subsystem breaker for connecting the cluster of electrical power subsystems to the power grid. The system further includes a reactive power compensation inverter electrically coupled within the electrical power system, the reactive power compensation inverter operable to increase the reactive power level in the electrical current flowing to the power grid.
