The invention discloses a power distribution network modeling method and system. The method comprises the following steps: acquiring power distribution network data at the current moment; judging whether the power distribution network data at the current moment is the same as the power distribution network data acquired last time or not; if not, extracting change data of the power distribution network data at the current moment compared with the power distribution network data acquired last time; classifying the change data according to preset structural categories of the power distribution network to obtain first power distribution network data; filtering invalid data in the first power distribution network data to obtain second power distribution network data; and establishing a power distribution network topological relation model according to the second power distribution network data. According to the invention, various conditions and change conditions of the power distribution network can be accurately displayed through the established topological relation model of the power distribution network, so that workers can manage, update and maintain the power distribution network.
Description
technical field [0001] The present application relates to the field of power systems, and more specifically, to a distribution network modeling method and system. Background technique [0002] Electric energy is the main driving force of various sectors of the national economy. The consequences of power system obstacles are often very serious, which will stop production in various industries, disrupt social order, bring inconvenience to people's lives, and even endanger the safety of people and equipment. cause huge losses. [0003] Under such circumstances, it is very important to fully and accurately grasp the overall structure and operation of the current power grid. With the development of the power system, the overall scale of the power grid is constantly expanding, and the structure of the power grid is becoming more and more complex. Simple summary charts or schematic diagrams of the power grid structure cannot accurately and clearly show the current power grid situa...
