A Hybrid Reference Signal Generator for Active Compensators

A new reference generation technique for active compensators based on the use of CPC theory along with the instantaneous reactive power (p-q) theory is presented here. Modifications to reference signal generation techniques based on instantaneous reactive power as well as to the synchronous reference frame (d-q) method are proposed. The proposed strategy utilizes the CPC theory instead of the filters typically used to extract the desired components of the current.  A simulation-based example is provided that shows this new approach retains the “instantaeous” property provided by the p-q or d-q methods under certain conditions without the negative effects found using the traditional method.
