摘要
对造成小负荷下陕西电网电压偏高的主要因素进行了总结;重点分析了各种因素对陕北电网、陕南电网电压调整的影响。利用无功优化软件,计算评估了陕西电网年最小负荷下的电压调整能力。根据计算可知,陕西电网现有的电压调整能力基本可以满足运行需要。陕北电网的电压状况随着4座330 kV变电站的投产将有明显改善,陕南电网的电压调整能力强于陕北电网。
Main factors that cause voltage increase of Shaanxi grid is summarized. The voltage regulation capability under minimum load in one year is calculated and evaluated by reactive power optimization software. The calculation shows that operation demand can be satisfied by the present voltage regulation capability. The various factors that influence the voltage of Northern Shaanxi grid and Southern Shaanxi grid are analyzed. With the operation of four 330 kV substations, the voltage status of Northern Shaanxi gird would be greatly improved. The Southern Shaanxi gird has better voltage regulation capability than the Northern Shaanxi grid.
