摘　　要：基于青海海南州地区网架薄弱,电网断面能力较小,无法满足清洁供暖负荷的增长需求,通过具体的清洁供暖负荷性质分析以及电网的运行方式调整,提出了最终保障负荷接入的实际解决方案,并为电网安全运行在现有装置的基础上提出了继电保护改造方案。In order to deal with the problems of weak grid structure,small cross-section capacity of the power grid and inability to meet the growing demand for clean heating loads in Hainan area in Qinghai,a practical solution to guarantee load access is proposed in this paper based on the specific analysis of the nature of clean heating load and the adjustment of the power grid operation mode,and a relay protection transformation scheme is proposed based on the existing devices to ensure the safe operation of the power grid.

关 键 词：清洁供暖 负荷性质 断面能力 运行方式
