Embodiment Construction

[0029] The following combination Figure 1 to Figure 3 Specifically, a Spark-based power system topological island rapid identification system and method provided by the present invention are described.

[0030] The electrical system topology island is a subsystem in the power system that is not connected to the outside world. The status of electrical components in the power system changes at any time. The CIM / E file describing the relationship between switch on-off and component connection is generally updated every 15 minutes. To perform real-time analysis and calculation of the system, it is necessary to quickly reconstruct and analyze the system topology after the grid status is updated. Subsequent power flow calculations, risk assessment and other advanced power algorithm applications are all based on topological analysis of electrical islands. In order to achieve the efficiency and speed of real-time analysis, the parallel graph calculation GraphX ​​component in the Spar...

Abstract

The invention relates to the technical field of power grid analysis, in particular to an electrical power system topological island fast identification system and method based on Spark, and the methodand system are applicable to topological analysis of large-scale power grid systems. By means of a large-scale parallel graph computing module GraphX under the Spark framework, a power grid topological graph is constructed; analysis treatment is carried out on the topological graph through parallel computing based on a memory to obtain topological islands in the power grid system; the GraphX parallel graph computing framework can achieve parallel computing analysis of the large-scale topological graph; as for the complex large-scale power grid system, by adopting the Graphx, the topological islands in the power grid can be fast identified and calculated.

Description

technical field [0001] The invention relates to the technical field of power grid analysis, in particular to a Spark-based power system topological island rapid identification system and method. Background technique [0002] Power system topology analysis is the analysis of the state of the components used for conversion, protection and control in the process of electric energy (production, transmission, use) flow, which is considered to have an impedance of approximately 0 in the power system analysis. A model that is convenient for power grid analysis and calculation, which is between the bottom layer and the top layer. As far as scheduling automation is concerned, low-level information (such as SCADA) is the basis of topology analysis, and high-level applications (such as state estimation, safety scheduling, etc.) are the purpose of topology analysis. It can be seen that in the real-time operation of the power system, the state changes of these components determine the c...
