Grid Synchronization of a Seven-Phase Wind Electric Generator Using d-q PLL
Energies, 2017Co-Authors: Kalaivani Chandramohan, Sanjeevikumar Padmanaban, Rajambal Kalyanasundaram, Mahajan Sagar Bhaskar, Lucian Mihet-popaAbstract:The evolving multiphase induction Generators (MPIGs) with more than three phases are receiving prominence in high power generation systems. This paper aims at the development of a comprehensive model of the Wind turbine driven seven-phase induction Generator (7PIG) along with the necessary power electronic converters and the controller for grid interface. The dynamic model of the system is developed in MATLAB/Simulink (R2015b, The MathWorks, Inc., Natick, MA, USA). A synchronous reference frame phase-locked loop (SRFPLL) system is incorporated for grid synchronization. The modeling aspects are detailed and the system response is observed for various Wind velocities. The effectiveness of the seven phase induction Generator is demonstrated with the fault tolerant capability and high output power with reduced phase current when compared to the conventional 3-phase Wind generation scheme. The response of the PLL is analysed and the results are presented.

Harmonic analysis of multilevel inverter driven by variable speed Wind Electric Generator
2013 International Conference on Green Computing Communication and Conservation of Energy (ICGCE), 2013Co-Authors: M. Vimala, C. ChellamuthuAbstract:The variable speed Wind Electric generation system was considered in this paper. The modeling of Wind turbine using Simplified C block available in PSIM software incorporating active pitch angle control is developed. The Maximum Power Point Tracking (MPPT) algorithm has been developed to extract maximum Wind power for all Wind speed below the rated value. The Wind turbine drives the Permanent Magnet Synchronous Generator (PMSG) feeding a diode bridge rectifier and DC-link capacitor. The constant DC voltage from DC-link capacitor is fed to an inverter which is connected to the three phase load. The study of Multi Level Inverter (MLI) has been carried out. The simulation of Diode - clamped MLI was performed using the elements available in the PSIM. The switched waveform of MLI has lower level of harmonic distortion when compared to two-level converter. Performance evaluation has been carried out. The load current, voltage, power output and efficiency of the converter system have been analyzed.

Intelligent controller for an isolated Wind energy conversion scheme
2006 India International Conference on Power Electronics, 2006Co-Authors: P.s. Mayurappriyan, C. Chellamuthu, K. Rajambal, J. JeromeAbstract:This paper focuses on individual controller designs for an isolated Wind Electric Generator supplying power to heating and voltage sensitive loads. The Wind driven self- excited induction Generator (SEIG) and other network components are modeled and simulated using Matlab/ Simulink. The variable voltage and frequency of a Generator is first rectified and the DC power is then transferred to the load through a DC link converter. By adjusting the modulation index of the PWM inverter, maximum power can be obtained from the system and the terminal voltage can be maintained constant under varying Wind velocities and load conditions. Design of two neuro controllers are proposed: 1) to maximize the power extraction from the Wind turbine for heating loads and 2) to regulate the terminal voltage for voltage sensitive loads.

Power flow analysis of a grid connected PMSG based direct driven Wind Electric Generator
IEEE-International Conference On Advances In Engineering Science And Management (ICAESM -2012), 2012Co-Authors: C. Janani, K. RajambalAbstract:This paper proposes a large scale Wind energy conversion system comprising a direct driven PMSG connected to the grid through a power electronic interface. The variable voltage variable frequency output from the Wind Generator is rectified, boosted and converted in to a fixed voltage fixed frequency output. The boost chopper maintains a constant DC at the inverter terminals. The modulation index of the inverter is adjusted to extract maximum power from the Wind. The system components such as Wind turbine, PMSG, power electronic interface are modeled in MATLAB/SIMULINK. The performance of the system is investigated for different Wind velocities. The effect of duty ratio and modulation index is studied and the results are presented.

a statistical investigation of Wind characteristics and Wind energy potential based on the weibull and rayleigh models in rwanda
Renewable Energy, 2010Co-Authors: Bonfils Safari, Jimmy GasoreAbstract:A Wind energy system converts the kinetic energy of the Wind into mechanical or Electrical energy that can be harnessed for practical uses and transform the economy of rural areas where access to water and Electricity is very restricted and industry is almost nonexistent in most of the developing countries like Rwanda. Assessing Wind power potential for a location is an imperative requirement before making a decision for the installation of Windmills or a Wind Electric Generator and evaluating plans for relating projects. The aim of the present study was to evaluate the potential of Wind resource in Rwanda and to constitute a database for the users of the Wind power. A time series of hourly daily measured Wind speed and Wind direction for the period between 1974 and 1993 on five main Rwandan meteorological stations was provided by the National Meteorology Department. Statistical methods applying Weibull and Rayleigh distribution were presented to evaluate the Wind speed characteristics and the Wind power potential at a height of 10m above ground level using hourly monthly average data. Those characteristics were extrapolated for higher levels in altitude. The results give a global picture of the distribution of the Wind potential in different locations of Rwanda.
