Abstract: 传统统一潮流控制器(UPFC)价格昂贵,损耗高,谐波含量高,在电力系统中不能很好地推广使用.文中提出一种混合型UPFC,它由"Sen" Transformer(ST)和传统UPFC串联组成,ST通过控制普通的有载调压开关,实现360°离散可调串联电压,UPFC利用电力电子开关原理实现360°连续可调的串联电压,两者共同工作起到控制系统潮流的作用.与传统大容量UPFC相比,混合型UPFC使用小容量UPFC,能够达到大容量UPFC的潮流控制范围,具有成本低、效率高、电磁兼容性好、谐波含量低、易于实现的优点,解决了导致现阶段UPFC不能推广使用最为重要的成本问题.混合型UPFC是具有极高性价比和效率的潮流控制器件,具有广阔的应用前景.
