Method and apparatus for dynamic load sharing |
摘要 |
A method for providing dynamic load sharing between a first and a second three phase system is disclosed, wherein the first and second three phase system are connected to a first and second three phase interleaved winding in a generator. The method comprises determining a first q-axis control signal for the first three phase system and a second q-axis control signal for the second three phase system based on a torque and/or power demand for the generator, determining a first d-axis control signal for the first three phase system and a second d-axis control signal for the second three phase system based on a coupling effect between the first and second three phase systems, and adjusting the q-axis control signals and d-axis control signals by including at least one feed forward compensation signal, wherein said at least one feed forward compensation signal is based on a coupling effect between the first and second three phase systems. |
