同步发电机（Synchronous Generator） 是一种将机械能转换为交流电能的旋转电机，其核心特征在于转子转速与定子绕组产生的旋转磁场转速严格同步。以下是其详细解释：
工作原理
同步发电机基于电磁感应定律和同步原理工作。当原动机（如汽轮机、水轮机）驱动转子旋转时，转子上的励磁绕组通入直流电产生恒定磁场。该磁场随转子旋转，切割静止的定子三相绕组，从而在定子绕组中感应出三相交流电动势。转子的机械转速($n$)与定子电流产生的旋转磁场转速($n_s$，即同步转速)始终保持一致，满足关系式：
$$
n = n_s = frac{120f}{P}
$$
其中，$f$为输出交流电频率（Hz），$P$为电机的磁极对数。这种转速的严格同步性是其名称的由来。

同步发电机（Synchronous Generator）是一种将机械能转换为交流电能的装置，其核心特点是转子转速与电网频率严格同步。以下从定义、原理、结构和应用场景进行详细解释：
同步发电机通过外部机械力（如涡轮机）驱动转子旋转，在定子绕组中感应出交流电。其转速（(n)，单位：r/min）与电网频率（(f)，单位：Hz）的关系由公式决定： $$ n = frac{120f}{P} $$ 其中，(P)为磁极对数。例如，在50Hz电网中，两极发电机（(P=1)）的转速为3000r/min。
局限性：同步发电机需严格保持转速同步，机械负载突变时易失步；现代变频技术通过电力电子装置可缓解此问题。
