Problems solved by technology

[0006] At present, the traditional short-circuit current calculation program in the operation and management of the power grid only calculates the 10 kV busbar of the substation, and the daily operation generally only performs short-circuit current verification on newly-built and renovated switchgears, while ignoring the overall consideration of the short-circuit current level of existing switchgears

Abstract

The invention relates to the technical field of power systems, in particular to a 10KV power distribution network GIS-based large-scale data quick calculation method. The method comprises the following steps of S1: defining a data source and a data collection object; S2: executing the specified data collection object to obtain specified field data, and importing an Excel file to a specified data page; S3: creating a short circuit calculation template page by a formula, a function and an array function in the Excel file, and taking a reference data page as an original data source in the calculation template page; and S4: executing a short circuit calculation program of an Excel template page to generate state information of a short circuit current of a 10KV device. Based on a device topologic relationship of a power distribution network GIS and conventional power network data, the 10KV switch device is simplified to node and branch models; modeling application is performed by applying ashort circuit current calculation principle; the short circuit level of the 10KV switch device is calculated and evaluated; and the method is applied to the electrical device type selection, the relay protection apparatus setting and the main wiring scheme and running mode determination.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a large-scale data fast calculation method based on a 10-kilovolt distribution network GIS system. Background technique [0002] The short-circuit current calculation program is one of the necessary system analysis tools for power systems. The conventional short-circuit calculation and analysis reaches the level of the 10 kV bus in the substation, and less attention is paid to the short-circuit level of the 10 kV distribution network outside the substation. [0003] With the continuous expansion of the scale of the urban power grid and the continuous improvement of the grid structure, the short-circuit current level of the regional power grid continues to increase. More and more substation 10 kV bus short-circuit currents exceed the 20 kA specified by the control level, while the current 10 kV switchgear Basically, the type selection is based on the breaking current of 20kA...
