|
摘要
统一电能质量调节器是一种综合治理调节电能质量的控制装置,可以对串联、并联补偿单元各自独立运行和协调控制两种工况下出现的电网电压跌落和电网电流谐波、无功电流等电能质量问题进行综合治理。首先分析了三相三线制UPQC的结构和各模块功能,然后采用同步坐标变换的畸变量检测算法和串联、并联协调控制策略,最后搭建UPQC实验平台,经过实验验证,UPQC在两种工况下对电能质量具有良好的治理能力。
Unified power quality conditioner is a control device for comprehensive regulating the power quality,can be a comprehensive treatment of series and parallel compensation unit grid voltage independent operation and coordinated control of two under the conditions of drop and current harmonics and reactive current of power quality problems. Firstly,the paper analyzes the structure of three-phase three-wire UPQC and the function of each module,and then the distortion detection algorithm and synchronous coordinate transformation of series and parallel coordination control strategy. Finally,the UPQC experimental platform is built. Through experimental verification,UPQC in the two conditions of the power quality is with good management ability.
