[IEEE 2018 53rd International Universities Power Engineering Conference (UPEC) - Glasgow, United Kingdom (2018.9.4-2018.9.7)] 2018 53rd International Universities Power Engineering Conference (UPEC) - Design of a PV-powered DC water pump system for irrigation: a case study
摘要： A PV-powered automatic irrigation system is designed and implemented in this paper. Dominant factors of the system such as the effect of solar radiation on motor power, current, and water discharge are considered in this study. The proposed system is implemented in the field to irrigate corn plant (maize) considering the optimum tilt angle for Duhok city. A new method for measuring the moisture content in the soil and sufficient level of moisture needed for normal growth of the crop is presented to design a timer for the system to reduce the amount of wasted water. Moisture sensors are used to check the availability of water in the soil and to enable the microcontroller to control the operation status of the pump. The results show that the proposed irrigation method is more accurate and efficient than the conventional irrigation methods in terms of the amount of the water used for irrigation, and the accuracy of irrigating times based on changing local climate. The results clearly demonstrate that the proposed system is more cost effective way of irrigation and more environmental friendly in terms of the amount of water used in an area known for water scarcity.

[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.
