UPFC直流电容的选择与设计

The selection and Design of the Capacity of UPFC Direct Current

直流母线电压对于由电压源型逆变器构成的UPFC装置的性能影响较大。本文分析了流过UPFC装置交流断面上的有功功率的组成,并从UPFC稳态和动态运行两个方面,分析影响直流母线电压的因素,对UPFC装置直流电容的选取和设计提出一些参考建议。

The voltage of DC bus impacts on the performance of an UPFC system based on Voltage-Sourced Inverter.This paper analyze component of active power exchanged in AC cross-section of UPFC system,and finds out relative factors affected the voltage of DC bus by stable and dynamic active power analysis in UPFC.We put forward some advice on the design and selection of DC Capacitor in UPFC system.
