溪洛渡水电站临时与永久供配电系统优化探讨

Discussion on optimization of temporary and permanent power supply and distribution system of Xiluodu Hydropower Station

介绍了溪洛渡水电站厂永久用电系统的设计规划和施工临时供电系统的组成与布置。根据溪洛渡水电站供电系统的特点,从110 k V变电站改造、左/右岸地下厂房10 k V备用电源配置等方面,对永久厂用电的形成施工期供电相互利用的优化方案开展了分析和研究;在此基础上,对后续电站永久厂用电的设计和规划进行了探讨并提出了合理化的建议。对于其他大型水力发电站的厂用电系统设计和施工具有一定的参考价值。

The design and planning of the permanent plant auxiliary power system of Xiluodu Hydropower Station and the constitution and layout of the temporary power supply system in construction period were systematically introduced. According to the characteristics of the power supply system of Xiluodu Hydropower Station, the optimization scheme for mutual utilization between the permanent plant auxiliary power generation and the temporary power supply in construction period were summarized in terms of the renovation of the 110kV substation, the standby power supply of underground powerhouses at the left and right bank. The sug- gestions on the follow - up design and the planning of the permanent plant auxiliary power system were summed up and put for-ward, which affords reference for design and construction of plant auxiliary power system of other large - scale hydropower stations.
