Abstract

Abstract: After in-depth analysis of field situation, an optimal power plant switchyard scheme design with high technical reliability and economic benefits is presented. A 220 kV substation in thermal power plant adopted the layout design to combine the areas of both switchyard and transformers outside of column A of gas turbine house instead of the traditional design to separate them into two exclusive areas. The new design optimizes general layout, improves space utilization rate, and clarifies the boundary among functional areas. It also improves device reliability and operation security, reduces operation and maintenance work load, and facilitates equipment installation and maintenance process. The environment friendly design also satisfies long-term expansion needs.

Key words: thermal power plants, switchyard, transformers, layout, optimization
