珊溪水库电站主要机电及自动化设备选型设计

Design of main electric equipment types for Sanxi Reservoir Project

珊溪水库电站装有 4× 5 0MW水轮发电机组 ,年发电量为 3 5 5亿kW·h ;电站以 2 2 0kV(出线 2回 )和 110kV(出线 4回 )两级电压接入电力系统 ;电站按“无人值班”(少人值守 )原则设计 ,由省中调统一调度。电站主要机电及自动化设备选型设计的主导思想为 :技术参数较先进、便于操作、检修维护工作量少、产品档次为中高挡 ;据上述要求进行设备设计选型及经招标择优选定生产厂家 。

The Sanxi Reservoir is located in the Wencheng County of Zhejiang Province. The hydropower station has four hydro generating units each with an installed capacity of 50 MW, with an annual energy output of 355 million kWh. The Station was connected with the power system through 2 outgoing loops of 220 kV and 4 outgoing loops of 110 kV. It is designed on the basis of the principle of unattended operation and dispatched by the provincial dispatching center. The guiding ideas of the selection of main electrical and automatic equipment types are as follows: advanced technical parameters, easy operation, less repair and maintenance amount. All these have laid a good foundation for the safe and unattended operation of the Station.
