摘要

建立了基于超级电容储能的配电网静止同步补偿器（DSTATCOM/UCES）小信号模型

采用功率前馈解耦的方法

实现了超级电容储能系统侧和配电网静止同步补偿器侧的解耦控制。分别采用单闭环和双闭环的控制方法对DC/DC双向变换器和DSTATCOM控制器进行设计。通过Matlab仿真验证了基于DSTATCOM/UCES可以有效改善配电网中的电压暂降和骤升等电能质量问题

同时也对控制器模型的正确性进行了分析。

Abstract

The small signal model of distribution static synchronous compensator based on the ultra-capacitor energy storage is established and the decoupling control is achieved on the system side of ultra-capacitor energy storage system and the side of static synchronous compensator of distribution grid by the use of power forward feed decoupling method. The bi-direction DC/DC converter using the control method of single closed-loop and double closed-loop control method is designed for distribution static synchronous. It is simulated and verified by Matlab that DSTATCOM /UCES can effectively improve the temporary rise and drop of voltage of distribution grid and

at the same time

the correctness of the controller model is analyzed.
