摘　　要：特高压磁阀式可控并联电抗器采用自抗扰控制离散算法可产生良好调节特性,提高特高压交流输电系统的无功平衡能力、提高电网的稳定性和供电质量。采用Matlab2008A和TMS320F28335高速浮点DSP为核心器件半实物仿真装置,对特高压输电系统进行了建模仿真和实时控制。试验结果表明,该控制算法可以适应磁阀式可控并联电抗器复杂非线性的控制特点,满足特高压线路中的无功功率高速响应要求。理论分析得到了在不同负载特性和全补偿条件下,特高压磁阀式可控电抗器的控制规律,为该装置工程设计提供了理论基础。The UHV magnetic-valve controllable parallel reactor（MVCR） adopts auto-disturbance rejection disperse arithmetic,which can produce favorable regulation characteristics and improve UHV AC transmission power, system stability and the quality of power supply. This paper adopts auto-disturbance rejection controller of floating point DSP TMS320F28335 as its hardware-in-the-loop simulation device and MATLAB2008A to model and simulation and real-time control for UHV transmission system .Test results show that the control algorithm is adaptive to the magnetic valve-controlled parallel reactor complex nonlinear control features,moreover, it is in response to high-speed reactive power requirements in the UHV lines.Theoretical analysis predicts the regulation of UHV magnetic-valve controllable parallel reactor controller under different load characteristics and full compensation conditions, meanwhile ,it provides theory foundation for this device project.
