  • Correlation of dielectric model parameters with experimental results based on PDC, RV and loss factor measurements for high voltage capacitors

    To improve the reliability and quality of electric power systems, preventive diagnosis and regular maintenance of high voltage capacitors are required. Dielectric response measurements in both time domain and frequency domain are potential tools for assessing the condition of dielectric of high voltage capacitors. Modern measurements in time domain include polarisation and depolarisation current ...

  • Wavelet feature–based modular neural network for detection and classification of power quality disturbances

    Disturbances such as voltage sag, swell, interruption and harmonics are very typical in a power system. Power quality monitoring should be capable of identifying these disturbances to initiate mitigation action and protect sensitive loads. This paper presents wavelet–neural network–based detection and classification of power quality disturbances. Wavelet transform has the ability to analyse ...

  • Diesel Tank Monitoring Solution

    This Case Study describes a solution for monitoring diesel tanks at remote locations. The solution is based on a smart level sensor at each field site and web monitoring software. The sensors measure level and calculate volume of the diesel in liters. This information is transmitted by SMS or GPRS over a GSM cellular network. Additional information is transmitted including temperature at the ...

  • Fuel Cell Voltage Monitoring Considerations

    Knowing what’s happening inside a fuel cell is a critical function, especially as fuel cells are continuing to be developed. One important aspect of this is to measure the voltageof each cell in a stack. Although this may sound trivial, it can be more complex and more expensive than it may at first appear due to high voltages, high channel counts,communication types, etc. There ...

  • A comparative study on solar array parameter extraction methods

    This paper presents a comparative study on different solar array parameter extraction methods such as a modified Newton–Raphson–based technique proposed in this work and two other popular techniques such as Bouzidi's Newton–Raphson method and Villalva's iterative method. A single–diode–five–parameter model is considered in this study for modelling the solar (PV) panel. The parameters of interest ...

  • Sensitivity analysis of component efficiencies on performance of a gas turbine cogeneration system

    The performance of a 1000 kW gas-turbine cogeneration system was evaluated in terms of performance measures, such as net power, exergy efficiency of the system, and the unit costs of electricity and steam. The efficiencies of some components that have a significant affect on the performance were taken as physical variables. Sensitivity was evaluated by introducing parameters, defined as the ratio ...

  • Photovoltaic string disconnect switches

    PV system arrays generate DC current. The solar modules are wired in series, and the system voltage is the sum of the maximum output voltage of all of the modules in a string. 600 Vdc maximum was chosen as an optimal system voltage to reduce installation costs by reducing conductor size and to stay below the 600V threshold in NEC Article 490. Prior to the growth in the number of installed PV ...
