ABSTRACT:
In an interconnection system (100) for transferring power between a first grid (22) operating at a first electrical frequency and voltage and a second grid (24) operating at a second electrical frequency and voltage, compensation circuits including a shunt compensation circuit (40) and a series compensation circuit (50) are provided for use in conjunction with a rotary transformer (102). The shunt compensation circuit (40) regulates voltage by adjusting reactive current injected in shunt, and is preferably connected between the first grid (22) and the rotary transformer (102). The series compensation circuit (50), which regulates e.g., reactive power flow through the rotary transformer (102), is preferably connected to a transformer (30) which interfaces the first grid (22) to the rotary transformer (102).
