The invention provides a factory station node layout method of a power grid tidal current chart based on virtual associated energy and relates to a node layout method. At present, automatic layout methods of nodes of a power transmission network include a genetic algorithm, a simulated annealing algorithm and various heuristic algorithms, but processing time, processing accuracy and processing stability are not all taken into consideration. The method includes the first step of obtaining all the factory station nodes needing to be laid out, the second step of checking whether a circuit exists between every two nodes, the third step of generating coordinates of all the nodes randomly, the fourth step of setting traversal counts of the nodes, the fifth step of calculating a virtual energy value between two adjacent nodes, the sixth step of checking whether the virtual energy value is smaller than a set value, and then processing the next node if the virtual energy value is smaller than the set value, the seventh step of correcting the coordinates if the virtual energy value is not smaller than the set value and calculating the virtual energy value, and the eighth step of finishing the layout when the node count is larger than the set value and then outputting an automatic layout result. Through the technical scheme of the method, position optimization of the factory station nodes can be completed with small complexity, and an abstract graph structure of the power grid is optimized in a very short time.
