本文阐明了110 kV变电站的概念及特性,提出变电站设计应注重的关键点,从电网模拟仿真分析、高效节能设备选型以及自动化与信息化技术应用三个角度,分析了110 kV变电站设计与设备选型的优化策略。研究结果表明,运用电网仿真对变电站供电区域的电网运行情况进行建模分析,找出稳定性的薄弱环节,可为变电站设计方案的优化提供依据;选用低损耗高效的变压器、断路器等节能设备,可显著降低变电站运维损耗,提升经济效益。

This paper first explains the concept and characteristics of 110 kV substation,and points out the key points that should be paid attention to in substation design.Then the optimization strategy of 110 kV substation design and equipment selection is analyzed from three aspects:power grid simulation analysis,high-efficiency energy-saving equipment selection and automation and information technology application.The results show that using the power grid simulation to model and analyze the power grid operation in the power supply area of the substation and find out the weak link of stability can provide a basis for the optimization of the substation design scheme.The selection of low-loss and high-efficiency transformers,circuit breakers and other energy-saving equipment can significantly reduce substation operation and maintenance losses and improve economic benefits.
