Evaluation of a solar power water pumping system in Mutomo, Kenya - A performance comparison between a submersible induction motor and a permanent magnet synchronous motor system

An existing solar-powered water pumping system located in Mutomo, Kenya has been evaluated in this paper. The requirement for this system is to produce a minimum of 25m³ water per day throughout the year.

The aim of this thesis is to investigate the performance of the currently installed system and find a suitable replacement in terms of efficiency and economic viability. In order to acquire the necessary knowledge for this project, a literature study was carried out to analyse the research within the area. Three simulation models were created which all include an electric motor driven by a photovoltaic array and are connected to a submersible groundwater pump. All models utilise space vector pulse width modulation. One model of an induction motor that represents the currently installed system, one induction motor that delivers a minimum of 25 m³ water per day, and one model of a permanent magnet synchronous motor for comparison. Simulations using weather data, representing an average day for each month of the year were carried out.  In order to compare the systems in terms of economic viability, price quotations from world leading manufacturers were acquired.
