Large power grid on-line data multi-thread rapid-integration method

Abstract

The invention provides a large power grid on-line data multi-thread rapid-integration method. The method comprises the steps of 1) reading and parsing various types of power grid data, storing the power grid data into an internal storage, and partitioning the internal storage according to the power grid data of power grid equipment of different types; 2) employing a parallel processing mode to associate the power grid equipment in each internal storage part after the partition with a corresponding topology node and establishing an association topology node list with respect to the topology nodes; and 3) zoning the topology nodes corresponding to the internal storage parts based on the partition of the internal storage, employing the parallel processing mode to conduct traversal analysis of the association topology node list of the topology nodes in each zone, performing topology island numbering of each topology node, eliminating dead topology islands, determining cared topology islands, conducting topology merging of all the zones of the topology nodes through tie lines among the zones of the topology nodes, and generating integrated power grid on-line data. The power grid data integration method provided by the invention is high in integration efficiency and rapid and highly efficient in processing procedure.

Description

technical field [0001] The invention relates to the field of power system simulation analysis and calculation, in particular to a multi-thread fast integration method for large power grid online data. Background technique [0002] The digital simulation of power system has become the main tool for power system planning, design, operation and analysis. The mathematical model of each component of the power system and the mathematical model of the whole system constituted by it are the basis of digital simulation of the power system. Models and parameters are important determinants of the accuracy of simulation results and directly affect the decision-making scheme based on them. [0003] The safe and reliable operation of the power grid is of great significance to social and economic development. With the continuous expansion of the grid scale, the continuous commissioning of generator sets, and the continuous access of UHV power transmission and renewable resource power, the...

Problems solved by technology

Traditional online data integration has the following disadvantages: 1) The integration process adopts a serial structure, and the speed is obviously slow when the amount of integrated data is large, making it difficult to meet the requirements of efficient and fast online applications; 2) Data integration is only simple data conversion, did not deal with the presence of erroneous data in the online data and did not quantitatively evaluate the quality of the online data
