同步發電機（Synchronous Generator） 是一種将機械能轉換為交流電能的旋轉電機，其核心特征在于轉子轉速與定子繞組産生的旋轉磁場轉速嚴格同步。以下是其詳細解釋：
工作原理
同步發電機基于電磁感應定律和同步原理工作。當原動機（如汽輪機、水輪機）驅動轉子旋轉時，轉子上的勵磁繞組通入直流電産生恒定磁場。該磁場隨轉子旋轉，切割靜止的定子三相繞組，從而在定子繞組中感應出三相交流電動勢。轉子的機械轉速($n$)與定子電流産生的旋轉磁場轉速($n_s$，即同步轉速)始終保持一緻，滿足關系式：
$$
n = n_s = frac{120f}{P}
$$
其中，$f$為輸出交流電頻率（Hz），$P$為電機的磁極對數。這種轉速的嚴格同步性是其名稱的由來。

同步發電機（Synchronous Generator）是一種将機械能轉換為交流電能的裝置，其核心特點是轉子轉速與電網頻率嚴格同步。以下從定義、原理、結構和應用場景進行詳細解釋：
同步發電機通過外部機械力（如渦輪機）驅動轉子旋轉，在定子繞組中感應出交流電。其轉速（(n)，單位：r/min）與電網頻率（(f)，單位：Hz）的關系由公式決定： $$ n = frac{120f}{P} $$ 其中，(P)為磁極對數。例如，在50Hz電網中，兩極發電機（(P=1)）的轉速為3000r/min。
局限性：同步發電機需嚴格保持轉速同步，機械負載突變時易失步；現代變頻技術通過電力電子裝置可緩解此問題。
