Influence of distributed phase modulator cluster on the DC transmission capacity of new energy gathering regional power grid Simulation Analysis

In view of the current requirements for short-circuit ratio of multi-site new energy stations and the requirements for transient overvoltage suppression of the power grid at the sending end, this paper analyzes the effects of centralized layout and distributed layout on short-circuit ratio and transient overvoltage suppression of multi-site new energy stations. This paper provides a certain reference for the new energy DC power grid to meet the requirements of multi-site short circuit and transient overvoltage suppression measures.
