有源电力滤波器是一种新型谐波、无功补偿装置，和传统的补偿装置相比，有源电力滤波器具有很大的优势：可以对谐波、无功以及负序电流实现实时、准确的补偿。 - The following is the main works and conclusions of this thesis . the novel upfc needs high power rate because it is generally used in high voltage transmission lines . after studied high - power converters and the literatures of upfc , the main circuit topology of novel upfc base on diode - clamping multilevel inverter is presented and the principle of using novel upfc to eliminate zero sequence and negative sequence currents is analyzed
本文所做的主要工作及得出的主要结论如下：由于upfc一般用于高压输电线，其功率等级要求很高，在综合研究大功率变换器和upfc现有文献的基础上，提出了基于二极管箝位多电平变换器的新型upfc的主电路拓扑，分析了用其来滤出高压输电线非全相运行时所产生的零序和负序电流的原理。 - Unified power flow controller ( upfc ) is one of the most powerful and most promising controllers of facts . if we use upfc to control the transmission parameters , terminal voltage , line impedance and phase angle in normal situation and use it to compensate zero sequence and negative sequence currents when one of transmission lines is cut off , we can implement two phases operating in high voltage transmission lines , which can improve stability and reliability for the transmission system
统一潮流控制器（ upfc ）是功能最强、最具发展潜力的灵活交流输电系统（ facts ）控制器之一，如果在常规条件下，用upfc实现输电线路的电压调节、移相、潮流控制、阻尼振荡等功能，在发生单相永久性接地或单相断路故障时，由传统的三相跳闸改为单相跳闸，用upfc的并补来滤除两端系统的零序和负序电流，用upfc的串补来提高输电线的传输功率，以实现两相长期运行，那么输电系统的稳定性、可靠性将大大提高。
