So, Sub-Stations are important part of power . An electrical substation is a subsidiary station of an electricity generation, transmission and distribution system where voltage is transformed from high to low or the reverse using transformers. Development of power electronics and mechanical engineering technologies, as well as the design of proper control strategies, has enabled wind generating units to possess performance comparable or even superior to those of conventional thermal or hydro generating units. Begamudre, New Age International (p) Ltd. 69 kV, 115 kV, 138 kV, 161 kV, 230 kV. Unit – II: Line and EHVAC Transmission Engineering by R. We engineers have presided over this growth and can feel justifiably proud of what it has brought society. Direct-current high voltage (dc HV). In turn, this geoelectric field creates what are known as geomagnetically induced currents, or GICs, which flow in any available conductor, including high-voltage transmission lines, oil and gas pipelines, railways, and undersea In the United States, the extra-high-voltage (EHV) portion of the power grid has grown by a factor of 10 [PDF] since the late 1950s. Ultra-High Voltage AC (UHVAC) and Current Source Converter HV/UHVDC (CSCHV/ UHVDC) are planned to be used in large capacity RE power transmission. Unit – I: Preliminaries: Necessity of EHV AC transmission – advantages and problems–power handling capacity and line losses- mechanical considerations – resistance of conductors – properties of bundled conductors – bundle spacing and bundle radius- Examples.
