| 摘要: |
| 随着远距离跨区直流输电规模持续增长，受端电网暂态电压稳定问题日益突出。研究 ±800 kV祁韶特高压直流投运后的湖南电网负荷中心暂态电压稳定性。首先，构建一种暂态电压稳定指标，并以湖南电网为算例验证该指标的有效性；然后，从实际电网运行需求出发，提出一种保证直流受端电网暂态电压稳定的运行控制实用方法，并将该方法应用于制定湖南电网运行控制策略；最后，分析影响湖南电网接纳特高压直流能力的主要因素。 |

| 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. |
