Grid Interactive Single Stage Solar Powered Water Pumping System Utilizing Improved Control Technique
摘要： This paper proposes a single stage grid interactive solar powered switched reluctance motor (SRM) driven water pumping system with an efficient control technique. The control of proposed system provides the proficient maximum power point technique (MPPT) tracking and motor drive control with bidirectional power flow between the photovoltaic (PV) array and single phase grid. It has harmonics components elimination, improved dynamic performance and a DC offset rejection capability compared to other control. A PV feed-forward term is also incorporated in developed control to enhance the dynamic performance of the system and to minimize the size of DC link capacitor with improved MPPT performance. The novel scheme of fundamental switching of SRM drive over its maximum operational time (when the grid is present) makes system efficient and reliable. An improved perturb and observe (P&O) based maximum power point tracking (MPPT) algorithm is used in this system to minimize the undesirable losses in a PV array specially under varying insolation levels. The proposed control is tested on a developed prototype and its suitability is authenticated through simulated and test results under various conditions.

摘要： This paper presents an improved designed induction motor, used for photovoltaic (PV) array fed water pumping system. The overall system is designed without a mechanical sensor to reduce both cost and complexity with simultaneous assurance of optimum power utilization of a PV array. The proposed system consists of an induction motor operated water pump, controlled by field-oriented control (FOC) with artificial neural network (ANN) current control technique. The MPPT (Maximum Power Point Tracking) as well as DC link voltage, is regulated by three-phase voltage source inverter (VSI). The estimation of motor speed eliminates the use of mechanical sensor and makes the system cheaper and robust. A new robust speed adaptive algorithm is presented, which is less dependent on parameters. A detailed study of various factors affecting the efficiency of the motor, is given to improve the behavior of the induction motor drive (IMD) for water pumping. The designed motor is tested on the developed prototype in the laboratory and its suitability is judged through various results under steady state and dynamic conditions of insolation variations.

[IEEE 2018 IEEE Energy Conversion Congress and Exposition (ECCE) - Portland, OR, USA (2018.9.23-2018.9.27)] 2018 IEEE Energy Conversion Congress and Exposition (ECCE) - A New Configuration of Dual Output Buck-Boost Converter for Solar Energized Water Pump Driven by Switched Reluctance Motor
摘要： This paper provides a new configuration of a single switch dual output Zeta derived DC-to-DC converter for an efficient harvesting of photovoltaic (PV) power for a 4-phase switched reluctance motor (SRM) driven irrigation pump. The system is essentially developed to minimize both cost and complexity, while synchronously guaranteeing optimal operation of the PV array. The proposed converter is derived from a hybrid of a ‘Zeta’ and CSC (Canonical Switching Cell) converters and so it contains all the benefits of both converters including instantaneous duty cycle, the switching node is shared by both Zeta and CSC converters. The proposed converter offers continuous power to drive, low ripple in output current and balanced dual output voltages supply. The CCM (Continuous Conduction Mode) working of proposed converter, helps to reduce the stress on its parameters and to increase its conversion performance. The PV power optimization and smooth automatic start of SRM, are the two major objectives of proposed DC-to-DC converter. A new deviation free maximum power point tracking (MPPT) technique is also used in proposed system. Moreover, the proposed MPPT control has an additional advantage of regulating the flow rate of water pumping by adjusting the duty cycle of proposed DC-to-DC converter. Overall, the proposed system provides a cost effective, efficient and maintenance free PV energized water pump.

Solar PV Powered-Sensorless BLDC Motor Driven Water Pump
摘要： This paper deals with a position sensorless brushless DC (BLDC) motor driven-solar photovoltaic (PV) fed water pump. A technique based on the back-EMF (Electromotive Force) zero crossing, is proposed for sensorless operation of the BLDC motor. The back-EMF is derived from the difference of line voltages. Thus, a requirement of neutral potential is eliminated. In addition, the proposed drive avoids the use of phase current sensors. The speed is automatically adjusted according the available peak power from the PV array. The devices of voltage source inverter (VSI), used to feed the BLDC motor-pump, are switched at fundamental frequency. This leads to the minimized switching losses. The responses of PV fed pumping system with the proposed drive, are observed under various operating conditions. The suitability of proposed topology is demonstrated through the hardware implementation.

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.
