基于Sen Transformer的新型统一潮流控制器的仿真与实验

摘要

The traditional unified power flow controller（UPFC） is well known of its flexible controlling ability,but is cannot be widely used in the power system for its disadvantage of high cost and low capacity.Sen Transformer has the advantages of high capacity and low cost,but its flexibility and action speed cannot content the requirement of accurate regulation.The hybrid power flow controller（HPFC）is constituted by traditional UPFC and ＂Sen Transformer＂（S.T.）in series and it has the advantages of high capacity and low cost.This paper firstly introduces the basic theory of HPFC,and then realizes the function of voltage and power control through the simulation of Matlab/Simulink,and at last realizes the control of voltage amplitude and phase,which does the research of HPFC from three aspects of theory,simulation and experiment.%传统统一潮流控制器（UPFC）控制功能灵活而卓越,但在电力系统中推广使用不具备容量和价格优势;Sen Transformer虽然容量大、成本低,但灵活性和动作速度都不能满足精确调节的要求。混合式潮流控制器（HPFC）是由统一潮流控制器（UPFC）和＂Sen Transformer＂（S.T.）串联组成,具有容量大、成本低等优点。本文首先介绍了HPFC的基本原理,然后通过Matlab/Simulink仿真验证了HPFC调节电压与功率的功能,最后通过搭建硬件实验平台,实现了HPFC调节系统电压幅值和相位的功能。从理论、仿真与实验三个方面对HPFC的调节电压和控制潮流的功能进行了研究和验证。
