复合式新型组合电器在南方电网110kV变电站标准设计中的应用

Application of the New Compound Combined Electrical Equipment in the Standard Design for 110kV Substations of the China Southern Power Grid

为满足南方电网安全、稳定和经济供电需求,选择适应中心城市电网建设特点的110kV变电站标准设计模式。介绍了110kV变电站标准设计方案中采用复合式新型组合电器设备的H类方案,详述了其输入条件(建设规模、电气主接线方式、短路电流控制)和选择PASS作为复合式新型组合电气设备的依据,分析了H类方案的特点,并将其与AIS、GIS设计方案进行了技术经济综合比较,可知复合式新型组合设备具有可靠性高、占地少、维护工作量少等特点,能较好地满足当今电网安全运行的要求。

To ensure the security,stability and economical power supply and developing demand of Southern Power Grid,it is necessary to present standard design mode for 110kV substation.Strategy H for new compound combined electrical equipment that is used in standard design for 110kV substation is introduced,its input conditions（such as construction scale,mode of main electrical connection and short-circuit current control） is discussed in detail,and the selection of PASS is used as the basis for new compound combined electrical equipment.The characteristic of strategy H is analyzed and compared with AIS and GIS design strategy.Results show that this equipment has higher reliability,less land occupation and lower maintenance work etc.,which can meet the requirement of operation security of current power grid.
