摘要

为提高配电网静止同步补偿器(D-STATCOM)控制系统动态性能和鲁棒性

提出一种基于输入-输出反馈线性化与积分滑模控制相结合的D-STATCOM控制方法。该方法利用输入-输出反馈线性化实现D-STATCOM有功电流与无功电流的解耦

消除D-STATCOM直流侧电容电压的非线性特性

使之在支撑公共耦合点(PCC)处电压的同时快速稳定直流侧电压

并利用积分滑模控制增强其对参数摄动的鲁棒性。仿真和物理实验结果表明

D-STATCOM采用文中提出的控制策略

配电网PCC处电压和直流侧电容电压均能快速、准确地调整到其参考值

并在外部干扰及参数变化时具有较强的鲁棒性。

Abstract

To improve the dynamic performance and robustness of a distribution static synchronous compensator (D-STATCOM) control system

an input-output feedback linearization technique combined with integral sliding mode control method for D-STATCOM is presented. Input-output feedback linearization technique enables the active current and reactive current decoupling for D-STATCOM

and eliminates the non-linear dynamics on capacitor voltage at DC side

which makes it much stable. The integral sliding mode control is also adopted to improve the D-STATCOM control robustness. The simulation and physical experimental results show that the voltages at point of common coupling (PCC) and DC voltage of D-STATCOM could track their references quickly and accurately. This control strategy is insensitive to external disturbances and parameter variations. This work is supported by Ph.D. Programs Foundation of Ministry of Education of China (No. 20110181120007).
