Embodiment approach

[0042] According to an embodiment of the present invention, the short-circuit current calculation module 20 can have the following functions:

[0043] (1) In the short-circuit current calculation module 20, three operating modes of the power system, maximum, minimum and normal, can be selected, and then the short-circuit current of the power system under different short-circuit faults can be calculated under the three operating modes of the maximum, minimum and normal.

[0044] (2) Multiple short-circuit points can be set, and the short-circuit current of each short-circuit position can be calculated at the same time under the multi-point short-circuit fault of the power system.

[0045] (3) Calculate the voltage of any node and the current of any branch in the power system.

[0046] figure 2 is a flowchart of a short-circuit current calculation method according to an embodiment of the present invention. Such as figure 2 As shown, according to an embodiment of the present...

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to a system for intelligent calculation of electric power systems. Background technique [0002] The power system is a complete system that completes electric energy production (power plant), transmission (transmission line), distribution (power distribution network, enterprise power supply network) and use (various electrical equipment). The power system needs to run uninterruptedly for a long time, and the power system equipment has the characteristics of wide distribution and many outdoor exposures. As modern society relies more and more on electric energy, the structure and distribution of power grids have become more and more complex, which has brought various difficulties to the relay protection work of power systems. As the planning and design unit of relay protection work, the electric power engineering design department aims to calculate according to the designed po...
