Research on Optimization Strategy for Design and Equipment Selection of 110 kV Substation
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.
