  • Voltage controlled stand-alone microhydro induction generator system

    The paper discusses simulated control cases of the wound rotor self-excited induction generator WRSEIG. The generator external controller is designed to regulate the output voltage and frequency for constant or variable speed operation of the prime mover and has the inherent capability of protecting the load from short circuit, which permits voltage collapse under heavy loads. WRSEIG is ...

  • Realizing energy savings in water processing applications using medium voltage adjustable frequency drives

    Why uptime and energy efficiency matter in water processing Making sure that systems and processes are up and running while improving energy efficiency (and cost) is crucial in water processing applications. During the recent recession, federal and municipal budgets tightened, limiting access to capital across the United States. At the same time, increased awareness of the ...

  • Software reliability estimation of computer relaying for transmission line protection using user-oriented software reliability model

    Advancement in signal processing techniques and VLSI technology has rapidly substituted conventional electromechanical relays with novel alternatives like digital relays, also termed as computer relays in power system parlance. A computer relay is considered as a digital signal processor which continuously processes the values of line currents and voltages. Hence, the heart of the computer relay ...

  • Risk assessment of catastrophic failures in electric power systems

    The declining reliability of the US electric power system is raising major concerns among both politicians and power engineers in the USA. One of the reasons put forward by the North Electric Reliability Council (NERC) is the detrimental role played by the protection systems during large disturbances, which tend to help the perturbations to propagate through over-tripping of fault free system ...

  • 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 ...

  • Impacts of dynamic reactive power compensation devices on the performance of wind power generators

    This paper investigates the main impacts of dynamic reactive power compensation devices on the performance of induction machine-based wind power generators. The dynamic reactive power compensation devices analysed are the SVC (Static Var Compensator) and the DSTATCOM (Distributed Static Synchronous Compensator). The usage of these devices as a power factor regulator or a voltage regulator is ...

  • Hydropower installation

    DSEP100 Mains Decoupling Relays for hydropower projects in remote locations in the Cumbrian Lake District, UK.  Old decommissioned water wheels in Ambleside, Blencathra and Langdale have been recently refurbished and brought back into use as sophisticated hydropower turbines which are now working in parallel with the grid, ...

  • Fault characteristics in electrical equipment

    Proper design and installation of electrical equipment minimizes the chance of electrical faults. Faults occur when the insulation system is compromised and current is allowed to flow through an unintentional path. IEEE Std 493 Recommended Practice for the Design of Reliable Industrial and Commercial Power Systems1 publishes data that reports that the vast majority of faults are classified as ...

  • Solar power generation by photovoltaic technology

    The various forms of solar energy, solar heat, solar photovoltaic, solar thermal electricity, and solar fuels offer a clean, climate-friendly, very abundant and in-exhaustive energy resource to mankind. Solar power is the conversion of sunlight into electricity, either directly using photovoltaic (PV), or indirectly using concentrated solar power (CSP). The research has been under way since the ...
