南方区域西电东送输电效益提升措施研究

  目的  针对现有水电消纳研究角度相对单一、定量和全局分析不足的问题，系统性研究云南富余水电消纳措施，量化分析未来一段时间内南方区域弃水形势。  方法  提出云南富余水电消纳方向，在此基础上明确西电东送通道输电能力及裕度。  结果  基于统筹协调的原则，有针对性地提出现有通道优化利用和两广断面输电能力提升两类清洁水电消纳措施。  结论  首次实现规划环节和调度运行环节的协调统一，进一步提高南方区域西电东送通道的利用效率和输电效益。

Research on Measures to Improve the Transmission Benefit of West-to-East Power Transmission in Southern Region

  Introduction   Aiming at the problems of relatively single perspective， inadequate quantitative and global analysis of existing research on hydropower absorption， this paper systematically studies the measures of Yunnan's surplus hydropower absorption， quantitatively analyses the situation of water releasing in the southern region in the future.   Method  This paper put forward the direction of Yunnan's surplus hydropower absorption， and defined the transmission capacity and margin of the west-to-east power transmission channel on this basis.  Result  Based on the principle of overall coordination， this paper purposefully puts forward two kinds of clean hydropower absorption measures， which are optimal utilization of existing channels and improvement of transmission capacity of Guangdong and Guangxi section.  Conclusion  This is the first time to achieve the coordination and unification of planning and dispatching operation links， and further improve the utilization efficiency and transmission benefit of the west-to-east power transmission in southern region.
