PPT-WIND LOAD ON ANTENNA STRUCTURES

WIND LOAD ON ANTENNA STRUCTURES PREPARED BY JANAK GAJJAR SD1909 Introduction Wind calculation Pressure distribution on Antenna Conclusion References Introduction Wind forces undoubtedly play a significant role in the design and operations of large steerable antennas and the need for satisfactory estimates of these forces is becoming increasingly evident.

Off-shore wind farm, dc cable is preferred for undersea use (no need of shunt reactive power compensation). Large-scale wind power, the existing ac system is already congested.
