    Keywords : data acquisition system; modbus; photovoltaics monitoring system;

    Abstract : The report is focused on the implementation of a data acquisition system that will be used for measuring different parameters which are needed in solar panel behavior analysis. To accomplish the DAQ system a DAQ board has been designed and implemented. READ MORE

  5. 4. Development of Wind Power Laboratory Setup

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Caspar Ralvenius; [2011]
    Keywords : Technology and Engineering;

    Abstract : Wind turbines are often used on weak grids as a source of active power. There is a desire for a continuous supply of active power during variable wind speeds while also supplying reactive power to suppress grid-voltage fluctuations. These objectives are attainable using converters which are controlled with regulators. READ MORE

  6. 5. Design of Harmonic Filters for Renewable Energy Applications

    University essay from Institutionen för kultur, energi och miljö

    Author : Bhunesh Kumar; [2011]
    Keywords : Digital Filter; Impulse Response; Wave Digital Filter; Circulator-Tree WAVE Digital Filter; Harmonics Filter; Renewable energy Filter; Wind Energy Filter; Butterworth; Chebyshev and Cauer filters; Low-pass; High-pass and Band-pass filters;

    Abstract : Harmonics are created by non-linear devices connected to the power system. Power system harmonics are multiples of the fundamental power system frequency and these harmonic frequencies can create distorted voltages and currents. Distortion of voltages and currents can affect the power system adversely causing power quality problems. READ MORE
