Parallel search method for generation of calculation bus of power distribution network

The invention relates to a method applied to an electric power system, in particular to a parallel search method for generation of a calculation bus of a power distribution network. According to the parallel search method for the generation of the calculation bus of the power distribution network, for the development of a radial power distribution network, searching is conducted starting from multiple feeder lines, and multiple probes search for nodes along the feeder lines and switches. When the probes of two threads 'collide' with each other, namely a node is locked by one probe firstly, the other probe needs to retreat to a node on the outer side of the closest feeder line on a retreating path of the probe along the retreating path instead of operating the node when the probe touches the node. By the adoption of the processing mode, safety of the threads can be guaranteed, and the integrity of the calculation bus is guaranteed. The parallel search method for the generation of the calculation bus of the power distribution network achieves the generation of the calculation bus of the power distribution network and solves the problem that the generation of the calculation bus of the power distribution network cannot be completed within ten seconds.
