摘要:
 将功率预测控制思想用于单相电压型并网变换器,通过二阶广义积分构造与电网电压、电
流正交的虚拟电压、电流分量来形成αβ 坐标系下的两相系统。建立了单相并网变换器在两相静
止和两相旋转坐标系下的数学模型。推导和分析了在旋转坐标系下的瞬时功率模型。利用此瞬时
功率模型来预测单相并网变换器的控制电压进而产生触发脉冲控制变换器。该策略具有控制系统
结构简单、开关频率固定、无需整定控制器参数、功率响应速度快、实现功率解耦控制的特点。1kW
样机的实验结果表明了方案的正确性和可行性。
Abstract:
 Power predictive control( PPC) was applied to single-phase voltage source converters,with the
actual single-phase input current and voltage,and a virtual quartered current and voltage were constructed
using second-order generalized integrator( SOGI) . Based on these electric parameters,a αβ coordinate
system was formed. The mathematical model of the two phase stationary and two phase rotating coordinate
frame were established respectively for single-phase voltage source converters. The instantaneous
power model of rotating coordinate frame was deduced and analyzed. The instantaneous power model was
used to predict the controlling voltage of the converters,and a trigger pulse was generated to control the
converters. The control strategy has some characteristics,such as easy designing,fixed switching frequency,
no need to adjust parameters of controller,with fast step response of the power,and realizing decoupled
power control. The feasibility and correctness of the control strategy are verified by experimental
results based on 1kW prototype.
