At present, the development of new power systems is facing major strategic tasks such as ensuring safe and reliable supply, accelerating clean and low-carbon transformation, and helping to achieve the "dual carbon" goal. As a hub platform for energy conversion, utilization and transmission configuration, improving the level of digitalization of the power grid is an inevitable trend, and it is also a practical need to build a new power system. Under the new power system, the power grid side is also expanding the volume of lines and the construction of pumped storage power stations to ensure the timely grid-connected consumption of energy. In order to ensure the holographic perception of power grid operation, a new generation of intelligent operation and inspection technology represented by UAVs is gradually realizing the inspection mode from human-machine collaboration to "machine generation".
