Abstract

The invention provides a power grid large-scale topological structure construction method and system. A stored power grid topological incidence matrix table is read to obtain sparse matrixes, MapReduce is utilized to process the sparse matrixes so as to obtain a stored power grid topological node analysis result, a power grid topological island connecting relation is calculated to obtain a power grid topological network result, and finally a power grid large-scale topological structure is established according to the power grid topological network result. Strict processing computation and processing process are adopted in the whole process, and accurate establishment is ensured. By utilizing a MapReduce expansibility advantage, the matrix computation complexity is simplified, a computation ending condition is optimized, quickness of large-scale sparse matrix computation is ensured, the large-scale power grid topological structure is quickly computed so as to facilitate accurate analysis on topological nodes and topological islands of a large power grid, and finally the power grid large-scale topological structure is efficiently and accurately established.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a method and system for constructing a large-scale topological structure of a power grid. Background technique [0002] The construction of power grid topology is to represent the network connected by various power equipment (such as generators, load feeders, shunt reactors, transformers, transmission lines, etc.) into a mathematical model that can be used for power system analysis and calculation according to the switch state. The basis for system simulation and analysis calculations. [0003] The construction of power network topology requires high real-time and reliability. With the upgrading of power grid construction, the demand for dynamic planning of power grid has become increasingly prominent. The future power grid is no longer a one-way hierarchical power grid, but a two-way In interactive power grids, changes in grid topology have become increasingly complex. It i...
