Abstract

The invention discloses a power system topology analysis method based on attribute graph, which comprises the following steps of: mapping electrical attributes such as an electrical island number, aninterval number, an on-off state and the like into element attributes of a topology graph in a process of constructing the topology graph according to power grid model equipment to obtain attribute points and attribute edges; creating the topological relationship according to the connection relation of electrical equipment in the power grid model to acquire the attribute graph, wherein the attribute graph is subjected to topological analysis through the depth-first algorithm, and analyzing the change of the electrical attribute of the electrical equipment. When the topological relationship iscreated, information density of the graph is improved. Therefore, the effects of simplifying topology search and improving the topology analysis efficiency of a power system are achieved.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a power system topology analysis method based on an attribute graph. Background technique [0002] The power grid topology is a valuable resource for power system analysis and control. Many problems in the power system are closely related to the power grid topology. For example, the chain-type narrow and long grid structure is closely related to transient stability problems; It provides convenience for problem handling and practical application, such as hierarchical partition control of reactive power and voltage; using the characteristics of power grid topology can also effectively improve the efficiency of power system problem analysis, such as topology decomposition and network segmentation in power system analysis and calculation. However, with the development of the power grid structure, many new power system analysis problems and difficulties are constantly emerging, su...
