Research on dynamic adjustment technology based on triangle structure SVG

采用SVG对配电网电能质量问题进行治理的方式运用较为普遍,它响应速度快、无功调节能力强、安全性能高。为确保低压配网系统电能质量的动态精确治理,本文提出了低压三角形拓扑结构SVG及其控制策略,并根据斯坦米兹理论设计了斯坦米兹综合控制和斯坦米兹分相控制两种算法。针对两种控制算法分别搭建了相应的仿真模型并进行了分析。分析发现,低压三角形结构的SVG对不平衡负载与无功电流具有一定的补偿效果。

SVG is widely used to deal with power quality proble ms of distribution network,which has fast response speed,strong reactive power regulation ability and high safety performance.In order to ensure the dynamic and accurate governance of the power quality of low-voltage distribution network system,this paper proposes the low-voltage triangular topology SVG and its control strategy,and designs two algorith ms based on steinmetz theory:steinmetz comprehensive control and steinmetz phase separation control.Corresponding simulation models are built and analyzed for the two control algorith ms.It is found that the low-voltage triangle structure SVG can compensate the unbalanced load and reactive current.
