| Abstract: | With the increasing growth of long distance trans-regional HVDC transmission system, the transient voltage stability problem of receiving-end system is becoming increasingly outstanding. The transient voltage stability of load center in Hunan Power Grid after the operation of ±800 kV Qilian-Shaoshan UHVDC project is researched. Firstly, a transient voltage stability index is constructed, and its effectiveness is verified by Hunan Power Grid. Secondly, from the perspective of operation demand of actual power grid, a practical operation control method is proposed to ensure the transient voltage stability of receiving-end system, which is employed to develop the operation control strategy of Hunan Power Grid. Lastly, the major factors affecting the UHVDC power receiving capability of Hunan Power Grid are analyzed. |
