Electrical Power Systems and Methods Using Distortion Filters

Abstract

An electrical power system 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. The converter power path includes a partial power transformer. The electrical power system further includes a subsystem breaker configured with each of the electrical power subsystems, and a cluster transformer for connecting each cluster of electrical power subsystems to the power grid. The electrical power system further includes a cluster power path extending between each subsystem breaker and the cluster transformer, and a distortion filter electrically coupled to the cluster transformer. The distortion filter reduces harmonics in current flowing from the electrical power subsystems to the cluster transformer.
