Abstract: As an important component of the power grid, the standardization and generalization of substation design and construction are key factors affecting project quality and progress. This paper analyzes and summarizes the problems encountered in recent years during the design and construction of general substation design schemes. On this basis, the standard design atlas for construction drawings is refined and improved. In practical projects, the local structural components of substations are further optimized through rolling updates of construction drawings, thereby reducing repetitive work for designers and improving overall design efficiency.
