[IEEE 2017 14th IEEE India Council International Conference (INDICON) - Roorkee (2017.12.15-2017.12.17)] 2017 14th IEEE India Council International Conference (INDICON) - An Effective Solar PV Fed Modified Vector Control of IMD for Water Pumping
摘要： The present paper deals with a speed sensorless technique of vector controlled induction motor drive fed from solar PV (Photovoltaic) array used for water pumping. This sensorless technique is based stator flux oriented in stationary reference frame. The special feature of the proposed topology is the additional feedforward loop added to the existing vector control loop, which makes it decoupled as a key feature of vector control. The mechanical sensorless induction motor drive is powered by solar photovoltaic (SPV) array to be utilized to drive the submersible water pump. The simulation of proposed topology is performed in MATLAB/Simulink environment and its performance is validated on test setup developed in the laboratory.

Reduced Current Sensor Based Solar PV Fed Motion Sensorless Induction Motor Drive for Water Pumping
摘要： This paper proposes a solar photovoltaic (PV) array fed induction motor (IM) drive operated water pumping system with an speed adaptive estimator. It focuses on the implementation of a space vector modulation (SVM) of voltage source inverter (VSI) without current sensors. The motor phase currents are estimated from the DC link current. The VSI is used for maximum power tracking and to drive an IM. A generalized integrator based flux adaptation approach is used to improve the drive performance. Moreover, a modified model reference adaptive system (MRAS) based speed estimation with rotor fluxes and stationary frame currents enhances its stability throughout the operating range. A modified algorithm based on incremental-conductance (InC) is proposed for maximum power point (MPP), which is used for peak power tracking at each insolation with a technique to control flow-rate. The overall system incorporating a single-stage PV powered space vector modulation (SVM) based VSI fed IM driven water pump is modeled and its performance is simulated in MATLAB/Simulink environment. The appropriateness of proposed system is verified experimentally on a prototype developed in the laboratory under various operating conditions.
