“…Qualitative analysis relating to this phenomenon has been reported in the literature [7,8] as well as the impact of the phenomenon on the motor and/or the cable [4,6,10,19]. Some mitigation techniques, especially to design output filters capable of matching the cable's characteristic impedance [1,13], have also been proposed.…”

“…Having Buck type converter design and too high DC operating voltage is one of the reasons for large difference in water output in summer and winter season even though the radiation on module plane is same. Lots of people have done research on the MPPT algorithms, based on constant voltage, perturb and observe, and incremental conductance methods (Moulay-Idriss and Mohamed, 2013; Kassem, 2012;Mohammedi et al, 2014) and effect of power quality on motor insulation (Persson, 1992;Bonnett, 1996;Melhorn and Tang, 1995;Hyypio, 1997;Daugherty and Wennerstrom, 1990;Mecker, 1992). Industry grade VFDs are traditionally used for solar water pumping systems to drive induction motors, however limitations in the performance of VFD encouraged researcher to design a new pump controller such as Sine-wave Pump Controller with MPPT (SPCM).…”

This paper presents a detailed comparison of two different electronic controllers used for driving Solar Photovoltaic water pumping systems in India. A recently developed Sine-wave Pump Controller with MPPT (SPCM) having two stage converter topology offered better performance throughout the operational range, over the most popular controllers using the Variable Frequency Drives (VFD). This paper presents an exhaustive study of SPCM and VFD based controllers in terms of their operational performance at 10 m, 18 m and 20 m head, in terms of quality of output power and quantity of the total water delivered when connected to the same motor-pump set under similar conditions. SPCM with best MPPT efficiency of 99.4%, lowest THD of less than 3% and pumped 30% to 70% more water for same heads. The overall system efficiency of SPCM based pump is 18% higher than VFD based pumping system for the head corresponding to duty point. The output power quality of SPCM is considerably high, with superior sine-wave (crest-factor 1.42 and 1.56 for voltage & current), ensures no voltage spikes even at 60 m of cable length. Thus, the paper establishes performance dominance of SPCM over the VFD based controller through the measurement on actual sample.

This work presents a new computation technique for incident and reflected waves as well as their associated over-voltages and Differential Mode (DM) currents along the Adjustable speed drive (ASD) cable. This method is based on developed mathematical formulas ready for numerical computations. Moreover, it allows simulation of the pulse voltage transients and their DM currents not only at the motor terminals but also at any point along the cable.The developed technique is highly recommended for the investigation of the over-voltage and the conducted EMI, due to the cable length. An approach for measuring required characteristics of the system has also been presented. It has been applied to an industrial 5 kVA ASD prototype using a 4-wire shielded long cable. The paper includes simulation results and experimental validations of the proposed technique.Index Terms-Cables, electromagnetic interference (EMI), electromagnetic transient propagation, overvoltage, insulated gate bipolar transistors, pulse width modulation, variable speed drives.
