Zaichenko Y. M. Adaptive control of the active power filter with selective harmonic compensation properties. – Manuscript. Dissertation for the candidate of technical science degree in specialty 05.09.03 “Electrotechnical Complexes and Systems” (141 – Electric Power Engineering, Electrical Engineering and Electromechanics). – National Technical University of Ukraine “Igor Sikorsky Kyiv Polytechnic Institute”, National Technical University of Ukraine “Igor Sikorsky Kyiv Polytechnic Institute”, Kyiv,2020.
In the dissertation the theory of analysis and synthesis of shunt active power filters control systems is developed. A new method for forming the feedback matrix of the network Current harmonic Observer has been developed, which ensures selectivity of estimating critical current harmonics and increased estimation speed. A method for controlling active filter currents is proposed and adaptive current testing algorithms are synthesized that guarantee simultaneous testing of given currents, estimation of higher harmonics, as well as the active resistance and inductance of the output choke. A method for controlling the voltage of the DC link SAF is developed, which provides partial linearization of the voltage subsystem and asymptotic regulation of the average values of the DC link voltage. The application of the obtained results makes it possible to significantly simplify the technical implementation of the SAF management system.
The results of the work are implemented: in the electrical power quality improvement systems by the company “Technoserviceprivod”, Kyiv, in the educational process at the National Technical University of Ukraine “Igor Sikorsky Kyiv Polytechnic Institute”.
Keywords: active power filter, electrical power quality, higher order harmonics, reactive power compensation.
