考虑过载风险的330 kV变压器并联运行负载优化控制算法OA

Parallel operation of multiple transformers is the main operation mode of 330 kV substations in the northwest power grid of China.Load distribution and dynamic optimization control of main transformers are the keys to ensuring the reliability,economy and safety of power supply in the power grid.For this purpose,it proposes a load control algorithm for multiple main transformers in multiple substations based on bidirectional long short-term memory networks and soft attention mechanisms.Firstly,it proposes the overload risk index based on the dynamic operation data of the main transformer.Then,it constructs the overload risk feature extraction of the 330 kV main transformer of the power grid based on the principle of bidirectional long short-term memory and the overload risk spatio-temporal feature fusion correction algorithm based on the soft attention mechanism.Finally,it establishes the main transformer load control algorithm based on the dynamic prediction of overload risk.It aims to enhance the operational economy and reliability of 330 kV parallel operation main transformers.
