Solar Photovoltaic System

This work presents the design of a 100kVA hybrid solar power system for Gollis University’s administrative block, Hargeisa, Somaliland. Prior to the system design, a preliminary field work on the site was performed to essentially measure the power/energy consumption of Gollis university’s administrative block. The results from the site survey was then used to select the appropriate equipment and instrument required for the design. This was achieved by calculating the energy consumption and then sizing the solar panel, battery, inverter and charge controller. The battery back-up time analysis at full load was also carried out to determine the effectiveness of the inverter size chosen. The inverter system was modeled and simulated using the MATLAB/Simulink software package. The simulation was used to study the reliability of the size of inverter chosen for the design, since the failure of most photovoltaic systems is ascribed to inverter failures. The results from the MATLAB/Simulink simulation showed that the inverter selected for the hybrid PV system has the ability to maximize the power produced from the PV array, and to generate sinusoidal AC voltage with minimum output distortion. The results also revealed that the PV solar system can provide a back-up time of 47.47 hours. The implications of the results are then discussed before presenting the recommendations for future works.

Vector Modulation

Multiphase electric motors have smaller torque pulsations and are more reliable that their three-phase alternatives. However, standard electricity grids around the world are three-phase, so power inverter is needed to drive multiphase motors. Inverter is used not only to power the motor, but also to control the am­plitude and frequency of the produced voltage, thus controlling motor speed and torque. Multiphase systems with odd number of phases have been widely investigated; therefore, this paper focuses on a six-phase inverter with a single neutral symmetrical load. A novel asymmetrical space vector modulation scheme is proposed and evaluated using simulations in Matlab/Simulink. Simulation results are compared to other modulation schemes. The proposed method is suitable for generating near-sinusoidal output voltages; however, it might not be suited for driving motors with sinusoidally distributed stator windings. Daugiafaziai elektros varikliai turi mažesnes sukimo momento pulsacijas ir didesnį patikimumą, lyginant su trifaziais varikliais. Pasaulyje paplitę trijų fazių elektros tinklai, todėl daugiafaziams varikliams maitinti reikalingi dažnio keitikliai, keičiantys standartinę vienfazę arba trifazę tinklo įtampą į daugiafazę. Dažnio keitiklis keičia ir išėjimo įtampos amplitudę, ir dažnį. Tai sudaro galimybių tiksliai valdyti variklio greitį. Literatūroje plačiai išnagrinėti daugiafazės įtampos formavimo metodai, esant nelyginiam fazių skaičiui. Darbe siūlomas naujas erdvinių vektorių asimetrinis įtampos formavimo algoritmas šešių fazių dažnio keitikliui, apkrautam simetrine apkrova su viena neutrale. Algoritmas tiriamas Matlab / Simulink programa, rezultatai palyginami su gautais, taikant kitus šešiafazės įtampos formavimo metodus.

ABSTRACT This paper explains the basics of the Linear Matrix Inequalities (LMI), with examples of simulations and calculations created in Matlab/Simulink programming environment where the controlled plant is the “Blue Lady” ship model. First chapter of this paper gives a short overview of publications describing the use of Linear Matrix Inequalities method. Second chapter contains basic definitions and equations for the LMI method. Chapter three presents the use of LMI method for ship control by describing controller synthesis for the “Blue Lady”. Chapter four compares the operation of two controllers, the first one consisting of three independent proper adjusted PID controllers and the second one being a multivariable LMI controller. Finally conclusions from the above comparison are drawn.
