摘要
针对负荷发展需要增加500 kV变电站容量的现状,以某省现有最终规模为2~3台主变的20座500 kV变电站为基础,从电气一次、电气二次、土建、线路角度对这类变电站超规模扩建主变的可行性进行分析,提出超规模扩建主变的指导原则,为500 kV变电站超规模扩建工程的设计和评审工作提供相关依据。
In view of the current situation that the load development needs to increase the capacity of 500 kV substation,based on the existing twenty 500 kV substations with the final scale of 2-3 main transformers in a province,the feasibility of the super scale expansion of the main transformer was analyzed from the perspectives of electrical primary,electrical secondary,civil engineering and line.The guiding principle of super scale expansion of main transformer was proposed,and relevant basis for the design and evaluation of 500 kV substation super scale expansion project was provided.
