  • Online condition monitoring of electrical power system imbalance

    Symmetrical components are of great importance in many applications in electrical power systems, such as power protection and condition monitoring. This paper presents a computer-based algorithm for online symmetrical components estimation. The proposed algorithm uses the samples of the phase variables (currents or voltages) to estimate the magnitude and phase angle of each phase phasor at each ...

  • Solar/wind power for noise monitoring terminals

    Solar Power Solutions A noise monitoring terminal’s (NMT) low power consumption and its ability to operate fully without power hungry cooling and heating units inside its enclosure mean that it is suitable for power from solar panels. The NMT may be continuously powered by battery which in turn is kept charged via solar energy. This solution is most appropriate in areas where there ...

  • Singular system analysis of the Local Power Range Monitor (LPRM) readings of a Boiling Water Reactor (BWR) in an unstable event

    Singular system analysis is a successful technique to separate oscillating components from a given signal. A methodology is proposed to apply this technique to the signals obtained from the LPRMs of a boiling water reactor core and extract the contributions of the in-phase oscillation and the out-of-phase oscillations from the LPRM readings during an unstable event. This methodology has been ...

  • Monitoring the Bavarian nuclear power plants online applying a Lagrangian model

    In 1997, the Monitoring System for Nuclear Power Plants (KFÜ) - located in the Bavarian office of environmental protection - was upgraded. The change included replacing the Gaussian plume model by a numerical dispersion model based on the Lagrangian theory. The KFÜ system allows the assessment of the doses workers receive in routine and emergency operation. Improvements of the new monitoring ...

  • Nuclear power plant on-line sensor calibration monitoring implementation issues

    The use of empirical models for on-line monitoring (OLM) of safety-critical instrumentation for calibration reduction has been investigated for over a decade. To help support the regulatory review of possible licence amendments for US nuclear power plants, a series of three NUREG/CRs is being developed for the US Nuclear Regulatory Commission. The third of these volumes, entitled 'Limiting Case ...

    The IAEA’s work in the area of nuclear power plant operating performance and life cycle management isaimed at enhancing the capability of Member States to utilize good engineering and management practicesdeveloped and transferred by the IAEA. In particular, the IAEA supports activities such as improving nuclearpower plant performance, plant life management, training, power uprating, operational ...

  • Sewer Level Monitoring System - a case study

    Background - The business of sewage level monitoring in sewers is accelerating across many countries. Strict regulations, the need to avoid environmental disasters, violation fines, early warnings and planning needs are just some of the forces shaping this growing trend.   Challenges Quantifying sewage flow and level is one of the most ...

  • Monitoring System for Hydrologic Evaluation of Landfill Covers

    Three test sections were constructed and instrumented to assess the hydrologic behavior of earthen final covers at two municipal solid waste landfills. A traditional design using a “resistive barrier” was used for two of the test sections, whereas an alternative design using a “capillary barrier” was used for the third test section. The test sections were built in two distinctly different ...
