摘要
电力系统的无功补偿与无功平衡是保证电压质量的基本条件。在保证系统中无功功率平衡的基础上,辅以有载调压等措施调整电压,才可使电压的偏移保持在允许范围内。文章通过对临汾500kV变电站无功功率平衡分析和主变压器调压计算,提出了对临汾500kV变电站低压侧无功补偿容量和主变压器调压方式选择的建议。
Reactive compensation and reactive equilibrium of electrical system are the basic conditions for guaranteeing voltage quality. Based on guaranteeing reactive power equilibrium of the system, only the voltage regulation assisted by on - load voltage regulation can make the deviation of voltage keep in allowable scope. Through analyzing reactive power equilibrium and calculating main transformer voltage regulation of Linfen's 500kV transformer substation, this paper puts forward the suggestions about selecting the reactive compensation capacity on low voltage side of Linfen 500k V transformer substation and the voltage regulation model of main transformer.
