A Verification Method of Overlapping Components in Power Grid Model

Abstract

The invention provides a check method for overlapped components in a power grid model. The check method comprises: finding out all electrical components in the power grid model; selecting any two of all the electrical components, and determining whether all endpoints of one electrical component are connected to the endpoints of the other electrical component; if so, determining that the two electrical components are the overlapped components; or if not, determining that no overlapped components exist in the power grid model. According to the check method for the overlapped components in the power grid model, the overlapped component error of the whole grid can be identified, an error positioning function is achieved, and the calculation amount in check is greatly reduced in a calculation mode of optimizing the distance between two points, thereby correcting the error in time, ensuring the correctness of a system model, effectively preventing an incorrect setting accident from occurring, ensuring the power grid to operate safely, and playing an important role in ensuring and improving economic benefits of power enterprises.

Description

technical field [0001] The invention relates to the technical field of power grid modeling, in particular to a verification method for overlapping elements in a power grid model. Background technique [0002] In order to ensure the safe and stable operation of the power system, it is necessary to have a full understanding of the physical characteristics and operating status of the power system. However, due to the high cost of conducting large-scale experiments in power systems, or the long observation time or short system response time and measurement difficulties, many field experiments cannot be realized. Therefore, computer simulations are increasingly used to replace Most of the field experiments. Simulation computing plays an important role in power system analysis. It extends people's observation ability, strengthens their thinking, simulation and calculation capabilities, and plays a decisive role in promoting the development of power system disciplines.

Problems solved by technology

[0006] All components have to be manually built one by one, and the power system itself does not have a reasonable and effective verification method for whether the established grid model is correct. The staff of the power system can only rely on the traditional means of "one look and two calculations" model correct or not

First of all, this kind of verification of the model is checked by the naked eye and followed by the feeling, and the staff generally lack the verification experience; secondly, it is passive, and only when the program fails to calculate normally, the problem is discovered and the cause is found.

It can be seen that this manual and passive calibration method is unscientific and very dangerous, and there is a possibility of safety accidents due to model errors at any time

Especially under the objective conditions of today’s large-scale power grid and large model area, once the power grid model is wrong, troubleshooting is like finding a needle in a haystack. The time for troubleshooting is unpredictable, and it is difficult to solve the problem in a short period of time, which seriously affects the commissioning of equipment on schedule.
