摘要:
电压型有源滤波器的数学模型呈现非线性特性,采用带有电流预测的无源控制算法对有源滤 波的变流器进行控制,可使其具备优良的动、静态特性.建立了并网逆变器欧拉-拉格朗日(Euler Lagrange,EL)数学模型,证明了电压型有源滤波器的逆变器是严格无源的,因逆变器具有无源性,所以可以控制能量在逆变器中的重新分布,控制器对吸收有功电流和输出无功电流分别进行控制,使系统能精确控制直流端电压以及快速精确跟踪负载的谐波电流、基波无功电流;然后采用计算机仿真和样机试验来进一步验证该算法的正确性,结果表明所研究的非线性控制策略可使有源滤波器具有明显的补偿效果.
Abstract:
Since the voltage and reactive power are two key factors of the power quality evaluation,how tocontrol the voltage and reactive power and making it within an acceptable range operation are of great signifi-cance. Voltage and reactive power control based on the traditional nine partitions exists oscillation question inswitch operation,however,the fuzzy control method that the substation voltage and reactive power control canavoid these problems. A substation voltage and reactive power fuzzy controller is proposed in the paper accord-ing to fuzzy control strategy,and the MATLAB simulation are made on the fuzzy controller,the analysis resultsprove that the fuzny controller designed in this paper can reduce the regulation numbers of transformer taps andshunt capacitors,meanwhile increase the service life of the substation equipment.
