摘要:  提出了基于电压源换流器型直流输电(High Voltage Direct Current Based on Voltage Source Converters,VSC-HVDC)线路作为分区联络线的黑启动方案,对区域电网实施软启动和恢复过程进行了研究.VSC-HVDC良好的电压、频率控制特性使得黑启动过程快速且平稳,不发生涌流和暂态过电压.通过PSCAD软件进行了仿真试验及数据分析, 验证了所提出的基于VSC-HVDC分区联络线黑启动方案的可行性.

Abstract:  A black start scheme based on voltage source converterbased HVDC(high voltage direct current)(VSC-HVDC) tie line was proposed. The ability of VSC-HVDC to softly energize major power system equipment is proved through simulation by PSCAD software. The voltage and frequency control ability of VSC-HVDC can ensure the process of restoration of the black system to be smoothly without inrush current and transient over voltage. The simulation results indicate that VSC-HVDC tie line is ideal to import black start power by using soft energizing control strategy and the proposed scheme of black start is feasible.

Key words: HVDC transmission technology, high voltage direct current based on voltage source converters(VSC-HVDC), black start, soft energizing
