摘要
虽然黄山电网处于系统末端,但由于负荷较小,导致电压偏高。文中针对黄山电网电压偏高的问题进行研究,提出利用低压电抗器吸收220kV线路的容性无功功率,从而降低系统电压,提高黄山电网电压质量的技术措施。经在220kV万安变2号主变35kV侧母线上装设容量为10Mvar的低压电抗器后,2006年7月投运至今,运行效果良好,地区电压质量有明显提高。
Due to Huangshan power network being located at the end of the system, the low loads came into being voltage rising. In order to solve the problem, feasibility study was proposed that the low voltage reactor should be installed to absorb the reactive power of the 220 kV line capacitance. Only by doing this, the voltage quality can be improved in Huangshan power network.After instalation of 10 Mvar low voltage reactors at 35 kV side of #2 main transformer in Wan'an substation, it obtains a well operation purpose,and obvious improve of area voltage quality.
