Power equalized hybrid control of PV fed induction motor pump

Operation of vector controlled induction motor pump amidst varying insolation condition poses many difficulties and frequently knocks out the drive from vector control. This paper presents a power equalized scheme for speed and torque estimation to realize vector control which adapts to varying insolation condition. Maximum power from PV is tracked through incremental conductance method, which in turn is translated into reference component for vector control induction motor pump. Simulation results in MATLAB environment are presented to validate effectiveness of control scheme under varying insolation levels.
