【摘要】：直流电源系统是水电站中重要的电气设备,其系统的稳定性和可靠性直接关系到整个电站的安全运行。结合国际项目巴基斯坦N-J水电站的厂房布置及机电设备的分布特点,简单介绍了直流电源系统的配置原则以及系统接线方案等内容;根据标准《IEEE Std 485固定应用的铅酸电池组尺寸确定的推荐实施规范》,重点介绍了直流电源系统设计中直流负荷统计、蓄电池数量及容量选择的计算等内容。最后,结合长江勘测规划设计研究有限责任公司近年来所参与的相关项目,对国内、外工程中的直流电源系统设计方式等方面的情况进行了分析比较,比较结果可为供水电站直流电源系统的设计提供参考。
[Abstract]:DC power supply system is an important electrical equipment in hydropower station. The stability and reliability of the system is directly related to the safe operation of the whole power station. Combined with the layout of the workshop and the distribution characteristics of the electromechanical equipment of the international project N-J Hydropower Station in Pakistan, the configuration principle of the DC power supply system and the system wiring scheme are briefly introduced. According to the standard < recommended Code of practice for determining the size of Lead-acid batteries for IEEE Std485 fixed applications, this paper mainly introduces the DC load statistics in the design of DC power supply system, the calculation of battery quantity and capacity selection and so on. Finally, combined with the related projects of the Yangtze River Survey Planning and Design Co., Ltd., this paper analyzes and compares the design methods of the DC power supply system in domestic and foreign projects. The comparison results can provide reference for the design of DC power supply system of hydropower station.
