Abstract

In the UHVDC transmission project

the overvoltage control function can provide sufficient reactive pow-er for the system and limit the amplitude of AC bus voltage. This article analyzes the action strategies and softwarelogic of overvoltage control

and it uses RTDS simulation system to deliver a simulation technique for various over-voltage situations under the typical operation of the UHVDC engineering

then the effectiveness of the engineering’sAC overvoltage control is verified through simulation. The analysis of the results has a certain technical support andreference value for the research and construction of Jiuquan-Hunan UHVDC engineering.
