Abstract: Safety supervision is essential for the reliable operation of power grids. And in the context of the widespread, multifactorial Changqing Oilfield power grid, it presents significant challenges. This paper introduces the current situation of safety supervision and management of oilfield power grids from the aspects of substation operation, construction transformation, transmission and distribution lines and distributed power supply. It puts forward corresponding countermeasures for strengthening safety supervision mechanism, enhancing safety supervision capacity, strengthening line operation and maintenance and applying new technology, thereby providing reference for the construction of safe and reliable oilfield power grids.

Key words: oilfield power grid, safety supervision, substation, transmission and distribution lines
