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±800kV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。
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.
