基于雷电预警的UHVDC系统主动雷击防护策略
|
摘要
提出了基于降压运行和直流紧急功率支援的主动防护思路,分析了在特高压直流输电系统遭受雷击故障时2种方法提高电网安全运行能力的作用。利用PSASP建立了四川电网丰大运行方式下包含特高压直流输电通道的仿真模型,基于系统稳定性判据,仿真分析了雷击造成各条特高压直流输电通道单极/双极闭锁时,降压运行控制和直流紧急功率支援控制对送端电网安全稳定性的影响。研究结果对确保含特高压直流输电系统的电网安全稳定运行具有参考价值。
The idea of active protection based on reduced-voltage operation and DC emergency power support are presented,and the effects of the two proposed methods on improving the safe operation of the power system under the lightning fault of the UHVDC system are analyzed. The simulation model of Sichuan Power Grid containing several UHVDC systems during the flood season is established with PSASP software. Based on the stability criterions of power system,the influences of the reduced-voltage operation and DC emergency power support control on the operation stability of the sending power grid when individual UHVDC system operates in monopolar/bipolar lockout mode due to the lightning strike are analyzed through simulations. The research results have reference value for ensuring the safe and stable operation of the power grid containing UHVDC transmission system.
