Abstract

The invention proposes an active control method and system of electromagnetic transient automatic modeling in large-scale power grid, belonging to the technical field of large-scale power grids. The method of the invention includes the following steps: result configuration parameters are converted, the configuration parameters include: a basic configuration parameter and a default configuration parameter; automatic modeling process control rules are determined, and the automatic modeling process control rules include: voltage source mode power grid modeling, generator mode power grid modelingand fault mode power grid modeling. The active control method and system of electromagnetic transient automatic modeling in the large-scale power grid actively controls generation types and the numberof elements in an electromagnetic transient model, so that the types and output scale of the generated elements in the electromagnetic transient model are controllable, and the intelligence of generation of a conversion model is improved, so as to meet various requirements of users for the simulation scale and simulation accuracy.

Description

technical field [0001] The invention relates to the technical field of large-scale power grids, and more specifically, to an active control method and system for automatic modeling of electromagnetic transients in large-scale power grids. Background technique [0002] With the rapid development and progress of my country's economy and society, energy security, climate change, and sustainable development have become major strategic issues for my country's economic and social development. In order to adapt to economic and social development, the State Grid Corporation of China has continued to promote the rapid development of UHV power grids in recent years, so that the main grid of the State Grid has shown the remarkable characteristics of AC-DC hybrid connection. [0003] Electromagnetic transient simulation is a more accurate technical method for simulating the operating characteristics of AC and DC power grids. However, for the electromagnetic transient simulation of large...
