This invention provides an active flow control method and system based on intelligent algorithms. The method includes: determining the number of inlet parameter sets for a typical flight state point, constrained by simulation economy and sampling efficiency; performing numerical simulations according to the number of inlet parameter sets to obtain dataset 1, with inlet parameters as independent variables and flow field characteristics as dependent variables; obtaining dataset 2, with flight state as independent variables and flow field characteristics as dependent variables, through numerical simulation for a certain set of inlet parameters; constructing a proxy model of inlet flow field characteristics for a typical flight state point using deep learning based on dataset 1; constructing a proxy model of inlet flow field characteristics for a wide-speed-domain flight state based on the proxy model of inlet flow field characteristics for the flight state point, using a transfer learning algorithm and dataset 2; constructing an environment-agent interaction model based on a deep reinforcement learning algorithm, using the proxy model of inlet flow field characteristics for a wide-speed-domain flight state as the environment model for deep reinforcement learning; setting optimization termination conditions based on the environment-agent interaction model, and obtaining a control sequence with continuously optimal inlet performance under different flight states through deep reinforcement learning. This invention can stably adapt to flight scenarios with a wide speed range and a large airspace, and achieve real-time optimal control of the air intake flow field under a wide speed range, solving the problem of poor generalization ability of traditional methods under different operating conditions.

The application relates to a kind of box-type substation monitoring data visualization method, belong to substation monitoring and visualization technical field.The application adds the required visualization primitive in box-type substation electrical vector diagram according to layer order, edits the ID, coordinate, animation, layer, group, relevant primitive and other properties of primitive, and is bound with the visualization information table of monitoring object primitive and monitoring data by electrical vector diagram;before the interaction of sensing data and visualization primitive, the address of monitoring data is used to replace the ID of monitoring object primitive;the many-to-one and one-to-many association between primitives is constructed according to the group, coordinate, relevant primitive properties and electrical transmission relationship of primitive by electrical vector diagram;the sensing data is directly pushed to the primitive of monitoring object from the address of monitoring data, so as to quickly realize data visualization expression according to the association between primitives.The application reduces the development difficulty of box-type substation monitoring data visualization, and improves the level of box-type substation digitization.
