摘要: This paper presents a mathematical model that can be used to analyze and study transient small signal stability of large multi-terminal HVDC networks. The describes converter ac side dc grid electromagnetic transients in detail, also incorporate basic controllers, such as current, voltage, active reactive power including voltage-active droop-control. Also, it shows the necessary interfacing procedures link dynamic equations control systems using balance equations, where semiconductor losses are incorporated. validity presented is confirmed against detail converters modeled by their switch models on six-terminal grid. Additionally, results illustrate model's ability predict response stability, which discussed.
