    "Power System Analysis" by Grainger & Stevenson

    I am looking at buying "Power System Analysis" by Grainger and Stevenson. This book seems to have mixed reviews, with the suggestion that an earlier edition (by the late professor Stevenson) may be a better book. Is anyone able to give an opinion or recommendation on either book, or...

    Long Distance Supply at Low Voltage

    Is there any practical limit to LV circuit length, and what are the limits? A small offshore platform will have 24V DC loads that look like they will translate to no greater than about 3 amps per phase at 415V/50Hz. The platform is to be about 12 km from the nearest 415V point of supply. It...

    Generator and VSD motor load

    A plant is to have a single high capacity power supply from the grid and this is to run in parallel (normally) with an on-site generator (part of a co-gen plant). The generator is slated to be a 12.5MVA 11kV machine, size determined by waste heat requirements. The electrical load is to be...

    Submarine Power Cables

    A proposed development will include a number of small offshore production platforms. Each platform load is 415V 10kW!! The distance to each is approximately 12km. We plan to provide power to each at 11kV, via submarine power cable, with each platform to include a suitable transformer to 415V...
