Abstract

Embodiments of the invention disclose a direct-current control system modeling method for real-time electromagnetic transient simulation, and aims at solving the technical problem that the simple control systems cannot satisfy the precision requirement, for real-time electromagnetic transient simulation, of direct-current systems in alternating / direct-current power grids, and cannot simulate operation state switching of the direct-current systems under a plurality of modes in real time.

Description

technical field [0001] The invention relates to the field of real-time electromagnetic transient simulation, in particular to a DC control system modeling method for real-time electromagnetic transient simulation. Background technique [0002] With the development of the AC-DC hybrid power grid, the AC-DC grid is showing the characteristics of increasing scale and deepening complexity, especially for the DC system connecting two AC grids, the transmission capacity of most channels is higher than that of the previous five-year plan. The time has more than doubled. In recent years, the topology of new DC projects has also evolved from bipolar twelve-pulse to bipolar twenty-four-pulse. At the same time as the development of DC transmission technology, it has also brought changes to the DC electromagnetic transient simulation technology. Many offline electromagnetic transient simulation methods have been difficult to undertake the calculation tasks of the DC system under the bac...
