The 78 MW Hiep Thanh wind power plant will be using wind turbines manufactured by Siemens Gamesa, code SG 5.0-145 IIB to generate electricity. Siemens Gamesa is a leading supplier of wind power solutions to customers globally. A key player and innovative pioneer in the renewable energy sector, with over 107 GW installed in 75 countries.

The conversion of wind energy into electricity for use is done with the following process: The wind turbine converts the kinetic energy of the wind into mechanical energy that rotates the rotor (blade + shaft) and through the transmission will rotate the generator and generate electricity. Devices such as brake, controller, generator, motion shaft…. Will be placed in the engine housing for protection (nacelle) and placed on top of the wind turbine (tower)

The generated 35kV voltage will be led to the control house through the control cabinets before connecting to the 110kV step up transformer. The 110kV step-up voltage will be connected to the transmission line and to the national grid system.

The turbine 5.0-145 IIB is a 3-bladed rotor with a nominal capacity of 5.0MW, blade length 71m, rotor diameter 145m, shaft height 90m, 102.5m, 127.5m and 165m depending on the dimension. tower height.

The SG 5.0-145 IIB wind turbines are regulated by an independent altitude control system in each wing. The control system allows the wind turbine to operate at variable speed, maximizing the energy generated at all times, as well as minimizing load and noise.
