摘要

本文研究了一种采用五电平中性点箝位电压源逆变器(VSI)的先进静态无功补偿器(ASVC)的建模和控制。在d-q轴坐标系下建立了五能级ASVC的非线性状态空间模型。该补偿器的有效性在很大程度上取决于控制策略的选择。将状态反馈控制(SFC)技术应用于交流输电网络对ASVC无功流进行调节，实现直流电压电容平衡。对基于ASVC的SFC控制器在多种工况下的动态性能进行了评价。仿真结果表明，与传统的比例积分(PI)控制相比，所提出的SFC控制策略具有很高的鲁棒性。

State feedback control of advanced static var compensator using a five-level NPC inverter topology

This paper deals with the modeling and control of an advanced static var compensator (ASVC) using a five-level neutral point-clamped (NPC) voltage source inverter (VSI). The nonlinear state space model of the five-level ASVC is obtained from the d-q axis frame. The effectiveness of this compensator highly depends on the choice of the control strategy. The proposed state feedback control (SFC) technique is applied to adjust the ASVC Var flow with the AC transmission network and achieve DC voltage capacitor balance. The dynamic performance of the ASVC based SFC controller is evaluated under several operating conditions. The simulation results demonstrate that the proposed SFC control strategy is highly robust compared to the conventional Proportional-Integral (PI) control.
