Problems solved by technology
[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a parallel search method for division of distribution network sections, which solves the problem of real-time division of distribution network sections and the time scale that is difficult to complete in ten seconds. The problem is that by parallelizing the feeder partitioning process, the feeder partitioning algorithm can be linearly accelerated while ensuring thread safety, so as to achieve feeder partitioning for several seconds for large-scale distribution networks

Embodiment Construction
[0027] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0028] One, explain the technical term that the present invention occurs below:
[0029] Terminals: the physical endpoints of feeder segments, switches, and distribution transformers.
[0030] Node: Two or more terminals connected together form a node.
[0031] Feeder section: It is a section of distribution line on which the magnitude and direction of the current do not change, and its two ends are places where the magnitude or direction of the current changes.
[0032] Feeder: A section of distribution line starting from the secondary side of the transformer in the substation and ending at the end of the line.
[0033] Distribution transformer: load transformer, which can refer to load.
[0034] Section: The smallest collection of elements enclosed by the end of a switch or feeder.
[0035] Depth: It is the attribu...

The invention relates to a method applied to an electric power system, in particular to a parallel search method for section division of a power distribution network. According to the parallel search method for the section division 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, namely the second node of the switch on a retreating path, on the outer side of the closest switch on the 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, the integrity of sections is guaranteed, and any integrated section is prevented from being divided by the multiple threads. The parallel search method for the section division of the power distribution network achieves the real-time section division of the power distribution network and solves the problem that the real-time section division of the power distribution network cannot be completed within ten seconds.
Description
technical field [0001] The invention relates to a method of an electric power system, in particular to a parallel search method for section division of a distribution network. Background technique [0002] The basic component types of distribution network include busbar, feeder section, circuit breaker, load switch, knife switch, distribution transformer, etc. There are many types, which are too trivial to be directly used in the electrical calculation of distribution network. The distribution network must be divided into sections, and the reliability and online risk can be calculated with the section as the unit, that is, the section division of the distribution network is a basic technology. [0003] For a large-scale distribution network with thousands of feeders (such as the distribution network of my country's first-tier cities and some provincial capital cities), the real-time division of distribution network segments is extremely challenging, and it is often difficult...
