摘要
针对2024年春节期间,鄂东局部电网电压持续偏高的问题,选取了电压偏高十分突出的陕武直流近区站点和凤凰山江夏片区的站点,详细研究了春节期间各站点滤波器、电抗器的投运,无功潮流的流动情况,并在此基础上分析了机组进相、新增电抗器对凤凰山江夏片区电压的影响,提出了枯水期小方式下电压运行的控制建议,研究结果对提升鄂东电网电压水平,保障电网的安全稳定运行具有重要意义。
During the Spring Festival in 2024,the voltage of local power grid in eastern Hubei Province continued to be slightly higher.In view of this problem,the paper selects the stations in the near area of Shaanxi-Wuhan DC transmission line where the voltage is significantly high and the stations in Fenghuangshan Jiangxia supply area to make detailed studies on the operation of filters and reactors at each station and the flow of reactive power during the Spring Festival,and then on this basis,analyzes the influence of leading phase operation of generator unit and added new reactors on voltage in Fenghuangshan Jiangxia supply area.Finally,the paper puts forward the control suggestions of voltage operation under small mode in low water period.The research results are of great significance for improving the voltage level of eastern Hubei power grid and ensuring the safe and stable operation of power grid.
