Basic Information
Scope
Main technical content: This document specifies the establishment of a mathematical model for electromechanical transient simulation of flexible DC grids used in the stability analysis and calculation of power systems, the requirements for parameter verification tests, and the preparation of modeling reports. This document is applicable to modular multilevel voltage source converters using bidirectional controllable power electronic devices such as IGBTs (Insulated Gate Bipolar Transistors) as the core converter elements, and the electromechanical transient modeling of high-voltage DC grids with DC-to-ground voltages of ±100 kV and above. It is not applicable to high-voltage DC transmission systems using current source converters. The model established in this document is not used to analyze three-phase asymmetric faults. For voltage levels below 100 kV and non-modular multilevel voltage source converter modeling, this document can be referenced.
