Due to global warming and climate change, all are looking for alternative power source with low price. So renewable energy is the only one option to spread all over the world. But technological and economical, it is now using compromised. we need to boost up the DC power to spread the application DC component, DC Transmission & distribution which reduce the power cost and intake the fossil fuel and clean and clear envieonment
In HVDC (400-500KV) transmission system to reduce transmission losses, generated AC power is stepped up from 21 KV to 400 KV in GT at generating station and then rectified to DC before transmitted in overhead lines more than 1000 KM distance. After reaching at destination the transmitted DC power is again converted into AC in inverter and stepped down to required voltage for end consumers. Such strategy reduces T&D losses from 15% to 7.5%.
Muduli Sir, actually i am thinking only renewable energy. most of the sources could be generated DC so it better to use dc alternate ac, and dc component which will be energy efficient. if Inverter and converter are used it wil be costly, any other option to step up without conversion
