水力发电机（Hydroelectric Generator）是水力发电系统的核心设备，通过将水流的动能转化为电能，为电网提供清洁能源。其工作原理基于电磁感应定律，主要由水轮机、发电机转子、定子及控制系统组成。当水流冲击水轮机叶片时，水轮机带动发电机转子旋转，切割磁感线产生感应电动势，最终通过变压器升压后输送至电网。
根据国际可再生能源机构（IRENA）的定义，现代水力发电机可分为两种类型：
美国能源部数据显示，水力发电机组的转换效率可达90%以上，远超其他可再生能源设备。典型应用包括抽水蓄能电站，这类系统在电网调峰中发挥关键作用，例如中国白鹤滩水电站使用的800兆瓦级水轮发电机组，其单机容量位居世界前列。
从环境效益角度看，联合国气候变化框架公约（UNFCCC）指出，水力发电机全生命周期碳排放强度仅为燃煤电厂的1/50，且具备长达50年的运行寿命。当前技术发展聚焦于磁悬浮轴承和智能控制系统，可提升低水头条件下的发电效率。
"Hydroelectric generator" 指水力发电机，由两个核心部分构成：
Hydroelectric（水电动力的）
Generator（发电机）
水流（如河流或水库）的势能通过涡轮转化为机械能，发电机进一步将机械能转化为电能。这一过程通过电磁感应原理实现，符合能量守恒定律：
$$
E{text{电能}} = eta cdot E{text{水能}}
$$
其中，$eta$ 是系统整体效率（通常为80-90%）。
若需进一步了解水电站类型（如抽水蓄能、径流式），可提供更详细的分类说明。
