  1. 1. MRS ( Multi Rotor System)
    Advantages
    Reduced Blade Weight and Lower Costs and Easier Power Rises
    Russell Assy Reduces weight, reduces tower and reduces parts cost
    Size reduction :
    • Easy to install (50% reduction in 2MW)
    • Easy repair service
    • Combination, easy transportation, cost reduction of commercial parts
    Reduced failure rate
    Power quality and efficiency rise
    Disadvantages
    Support frame increase Weight increase
    Overall system complexity
    Distributed Rotor Rotational Vibration and Main Structure
    Complex vibration problem
  2. Technology Evolution
    Multi Rotor System for installation cost only 10%
  3. 2. DAWT ( diffuser argument wind turvine)
    DAWT
    The inlet / outlet pressure and flow velocity are the same m˙ = (ρAU) 1 = (ρAU) 4 Bernoulli principle Application
    (2.5 times experimental paper), smaller turbine size (100 KW: 22 m dia → 13 m)
    Noise reduction (about 10 times)
    Increased stability (protection against blade breakage)

  4. 3. Combination
    Westec Inc Invention Model
    The efficiency of multi rotor system of type of the wind turbine is better than single turbine. (Ref. attachment)
