Then, what are the problems faced by power grid transmission, and how is high voltage technology needed and developed? That's just like last time, because the energy base is usually far away from the power load center, it needs long-distance and large-capacity transmission. Great line loss and heat will occur at a long distance, and the stability of power system and large capacity should keep Pmax not lower than the lower limit, so the measures to increase transmission voltage came into being. I believe everyone has such experience: driving on the highway in the suburbs. The high-rise buildings around the city have long disappeared, but the tall and continuous wire towers come into view in the open field of vision-the road is accompanied by people who have long been used to it. So, let's rethink why there are so many tall wires. This is because we need high voltage and long distance transmission. Then why high voltage and long distance transmission? I will talk about my understanding from four aspects as to why it is necessary to read relevant courses and network materials during power transmission. 1. the main reasons and necessity of high voltage technology 2. the reasons of high voltage and long distance transmission 3.
