摘要
本文评估永州电厂两台1000 MW机组接入系统对湖南电网带来的问题及影响,提出应对措施和建议。基于三种典型方式下的静态安全分析结果,得到永州电厂送出存在的问题。结合湖南负荷中心和湘南地区电网暂态电压稳定特性,开展永州电厂机组对电网暂态电压支撑能力的研究。最后对永州电厂接入系统的短路电流进行了校核,为后续永州电厂投产运行控制提供参考。
This paper assesses the problems and impacts on Hunan power grid with two 1000 MW units of Yongzhou Power Plant integration,and proposes suggestion of operation and control.Based on the static safety analysis results under three typical scenes,the problems existing in the transmission of Yongzhou Power Plant are obtained.Based on the transient voltage stability characteristics of the power grids in Hunan load center and Xiangnan area,the research on the transient voltage support capacity of Yongzhou Power Plant units is carried out.Finally,the short-circuit current of Yongzhou Power Plant's access system is checked.The research conclusions provide a reference for the follow-up operation and control of Yongzhou Power Plant.
