A Grid-Interactive Permanent-Magnet Synchronous Motor-Driven Solar Water-Pumping System
IEEE Transactions on Industry Applications, 2018Co-Authors: Bhim Singh, Shadab MurshidAbstract:This paper deals with an effective power transfer scheme between the solar photovoltaic (PV) array and single-phase grid, feeding a field-oriented-controlled (FOC) permanent-magnet synchronous motor (PMSM) drive applied to a water-Pumping System (WPS). Owing to the intermittency associated with solar (PV) System, the requirement of constant water supply is not possible with the standalone System. In order to mitigate this, a grid-intergraded WPS is proposed here. The grid integration enables the consumer an uninterrupted operation of water pump irrespective of solar insolation level. Moreover, the PV power can be fed to the utility grid when water Pumping is not required. To make it possible, one voltage-source converter (VSC) and one voltage-source inverter connected to a common dc link are used for utility grid and PMSM control, respectively. The unit vector template theory is utilized to generate switching pulses for VSC to control the bidirectional power flow between the solar PV System and utility grid through the common dc link. A sensorless FOC is used to drive the PMSM coupled to the water pump. An intermediate stage boost converter is used for extracting optimum power from solar PV array under variable insolation. A perturb and observe algorithm is used for generating the duty ratio for the maximum power point (MPP) operation. The applicability of overall System constituting utility grid in conjugation with PV array fed PMSM-coupled water pump ensuring bidirectional power flow control with MPP tracking of PV array and abiding the utility grid, IEEE-519 standard for power factor, and total harmonic distortion is simulated in MATLAB/Simulink environment with SimPowerSystem toolbox and validated on a prototype developed in the laboratory. The System prototype is tested under variable solar insolation and grid abnormalities such as voltage sag and voltage swell.

IEEE Transactions on Industry Applications, 2018Co-Authors: Him Singh, Utkarsh Sharma, Shailendra KumaAbstract:A simple and efficient solar photovoltaic (PV) water Pumping System utilizing an induction motor drive (IMD) is presented in this paper. This solar PV water Pumping System comprises two stages of power conversion. The first stage extracts the maximum power from a solar PV array by controlling the duty ratio of a dc–dc boost converter. The dc bus voltage is maintained by the controlling the motor speed. This regulation helps in the reduction of motor losses by reducing motor currents at higher voltage for the same power injection. To control the duty ratio, an incremental conductance based maximum power point tracking (MPPT) control technique is utilized. A scalar-controlled voltage source inverter serves the purpose of operating an IMD. The stator frequency reference of IMD is generated by the proposed control scheme. The proposed System is modeled, and its performance is simulated in detail. The scalar control eliminates the requirement of a speed sensor/encoder. Consequently, the need of motor current sensor is also eliminated. Moreover, the dynamics are improved by an additional speed feedforward term in the control scheme. The proposed control scheme makes the System inherently immune to the variation in the pump constant. The prototype of PV-powered IMD emulating the pump characteristics is developed in the laboratory to examine the performance under different operating conditions.

Iet Electric Power Applications, 2017Co-Authors: Anjanee Kuma Mishra, Him SinghAbstract:The aim of present study is to develop a `Luo' converter-based low-cost solar powered water Pumping scheme utilising a switched reluctance motor (SRM). The speed of SRM drive is controlled by adjusting the DC-bus voltage of split-capacitor converter. The converter is electronically commutated at fundamental frequency for low switching losses. A `Luo' DC-DC converter working in continuous inductor current and capacitor voltage modes (continuous inductor current mode and continuous capacitor voltage mode) is utilised to feed power to SRM drive through a split-capacitor converter. It also provides the limitless sector of maximum power point tracking (MPPT). The elimination of current and voltage sensors on the motor side owing to variable speed operation of the motor drive makes the System cost-effective and reliable. The soft-starting of SRM drive is also achieved through the proper step size and initial duty cycle selection through MPPT algorithm. The performance of SRM System is validated by both Simulink/MATLAB platform-based model and responses of developed prototype.

IEEE Industry Applications Society Annual Meeting, 2016Co-Authors: Anjanee Kuma Mishra, Him SinghAbstract:The present paper describes the solution for cost effective and efficient single stage photovoltaic (PV) generator powered water Pumping using a Switched Reluctance motor (SRM). An optimal selection of a perturbation size (ΔD) and an initial duty ratio (D) in incremental conductance (IC) MPPT (Maximum Power Point Tracking) algorithm facilitate soft starting to SRM by building up the voltage across split capacitors of a SRM converter with a reduced rate. The speed of SRM drive is controlled by output maximum power point (MPP) current of PV array. This avoids the current and voltage sensors on motor side. The proposed single stage System is operated under pulse width modulation (PWM) switching of a mid-point converter and gives privileged to reduce the bulky DC link split capacitors with small capacitors. A turn- off angle dependent control algorithm to self start a proposed SRM drive is also introduced in present System. Moreover, the present paper also discussed the details of System design and analysis of its performance under varying environmental conditions. The suitability of proposed System is validated using MATLAB simulation and test results on a hardware prototype.

Energy Policy, 2009Co-Authors: A Hamidat, B BenyoucefAbstract:In this work, the performances of the photovoltaic Pumping destined to supply drinking water in remote and scattered small villages have been studied. The methodology adopted proposes various procedures based on the water consumption profiles, total head, tank capacity and photovoltaic array peak power. A method of the load losses probability (LLP) has been used to optimize sizing of the photovoltaic Pumping Systems with a similarity between the storage energy in batteries and water in tanks. The results were carried out using measured meteorological data for four localities in Algeria: Algiers and Oran in the north, Bechar and Tamanrasset in the south. The results show that the performance of the photovoltaic Pumping System depends deeply on the Pumping total head and the peak power of the photovoltaic array. Also, for the southern localities, the LLP method shows that the size of the photovoltaic array varies versus LLP on a small scale. On the other hand, for the northern localities, the sizing of the photovoltaic array is situated on a large scale power. Because of the current high crud-oil price, the photovoltaic Pumping still to be the best adopted energy resource to supply drinking water in remote and scattered villages.

solar powered water Pumping System employing switched reluctance motor drive
IEEE Transactions on Industry Applications, 2016Co-Authors: Bhim Singh, Anjanee Kumar Mishra, Rajan KumarAbstract:This paper presents a solar photovoltaic array fed water Pumping System employing a switched reluctance motor (SRM) drive. The electronic commutation of the SRM drive at fundamental frequency offers reduced switching losses in a mid-point converter and considerably increases the efficiency of proposed System. The speed of SRM is controlled by varying the dc-bus voltage of the mid-point converter. A dc–dc Cuk converter operating in continuous conduction mode (CCM) is used for dc-bus voltage control. The CCM operation of inductors helps to reduce the ringing effect and decreases the losses of dc–dc converter. Current and voltage stresses on devices including switching stress of Cuk converter are also reduced in CCM. The Cuk converter facilitates the continuous and smooth input/output currents to SRM drive with boundless region for maximum power point tracking (MPPT) operation. The adjustment in step size of an incremental conductance MPPT algorithm facilitates the soft starting of SRM drive. The proposed System, subjected to dynamically atmospheric conditions is designed, modeled, and simulated using MATLAB/Simulink environment. A prototype of proposed configuration is also developed and its performance is validated with test results for the control of speed over varying insolation levels.
