Research on Key Points of Quality Control of Power Transformer Installation and Construction Based on GAT

Power transformer is an indispensable and important equipment in the power system, which can convert high-voltage electrical energy into low-voltage electrical energy to meet the needs of different electrical equipment. In the installation process of power transformer, the correct installation method is directly related to the safety and stable operation of power system. However, the existing optimal configuration scheme of the treatment device fails to consider the fault of the straightening device. Therefore, in view of the shortcomings of relevant research, this paper proposes an installation strategy of transformer DC bias straightening device based on GAT algorithm, which can comprehensively consider the cost and treatment effect. This paper establishes an installation strategy optimization model which takes the weighting of installation and maintenance cost and transformer neutral current value as the optimization objective function and takes the DC current of all transformer neutral points as the constraint condition. Finally, it is proved by experiments. The key points of quality control of power transformer installation and construction based on GAT proposed in this paper can quickly and effectively obtain the optimal configuration scheme of the substations in the regional power grid.
