Abstract

This paper presents the vector control of single phase induction motor(SPIM) to operate water pumping system using PV system with a maximum power point tracking(MPPT). The water pumping system uses a variable speed SPIM driven a centrifugal pump by field oriented control(FOC) inverter. The MPPT using a DC-DC converter controlled the duty cycle to track maximum power from PV under different insolation conditions. The duty cycle directly relate with a flux producing current control($i_{ds}$). The FOC inverter uses a current control voltage source inverter(CC-VSI). The simulation results are shown that the characteristics and performance of drive system, which varies as each conditions of light by expresses in voltage($V_{dq}$), current($I_{dq}$), speed of motor and torque.

본 논문은 최대전력점추적을 하는 PV 시스템을 이용한 점핑시스템 구동을 위한 단상유도전동기의 벡터제어를 제시한다. 펌핑시스템은 벡터제어에 의한 원심 펌프를 구동하는 가변속 단상유도전동기를 사용한다. DC-DC 컨버터를 이용한 MPPT는 다양한 일사량에 따라 최대 전력을 추적하기 위해 듀티 사이클을 제어한다. 듀티 사이클은 자속을 발생시키는 전류($i_{ds}$)와 직접적인 관계가 있다. 벡터제어 인버터는 CC-VSI를 사용한다. 시뮬레이션 결과는 일사량 변화에 따른 전압($V_{dq}$), 전류($I_{dq}$), 전동기 속도, 토크 등의 성능 및 특성을 나타낸다.
