关于新一代智能变电站交流站用电设计优化

Design Optimization of the New generation Intelligent Substation's AC Station Power

根据新一代智能变电站"两型三新一化"的建设标准,以国家电网公司某220 k V变电站新建工程设计竞赛项目的获奖方案为依托,对变电站交流站用电负荷进行梳理、分析及筛选,合理优化负荷配置,简化交流负荷回路。对站用变压器经行全寿命周期技术经济进行比较,合理选择站用变型式类型及其容量,降低全站能源损耗。

According to the standards of the construction of a new generation of intelligent substation ＂Liangxing Sanxin Yihua＂, and based on a winning scheme of new project design competition in 220 k V transformer substation of State Grid Corporation, the power load of substation communication station is sort out, analyzed and filtered to reasonably optimize the load allocation and simplify the AC load circuit. A technical and economic comparison of the whole life cycle of the station with a transformer is conducted to reasonably chose station with variant type and capacity and reduce total energy loss.
