基于多功能光伏并网逆变器的电能质量调节系统
A power quality regulatory system based on multi-functional photovoltaic grid-connected inverter
摘要
Abstract
In view of the power qulity problems , such as harmonics , reactive power and unbalanced current at point of common coupling of a distributed grid , a compound control strategy of photovoltaic grid-connected generation and pow-er quality regulation function based on LCL filter is proposed in this paper .The multi-functional inverter can inject ac-tive power into the distributed grid and and compensate the harmonics , load reactive power , and three-phase unbal-anced current in the grid-connected site .So it can improve the power quality and decrease the hardware investment . In addition, it gives an algorithm with no phase-locked loop, and designs a grid-current tracker with current weighted . In the end, the feasibility and effectiveness of the relevant design is verified by PSCAD /EMTDC.关键词
