摘要
为了研究静止同步补偿器实现有源滤波的功能,依据采样控制理论中的面积等效原理,提出了STATCOM等脉波电平不等时隙的控制方法,建立了这种新的控制方法的数学模型,并推导了主电路中电感和电容的计算公式。新的控制方法能使STATCOM输出正弦和非正弦波形,实现无功补偿和有源滤波的功能,电感和电容的计算公式简洁明了,能直接运用于工程设计当中。
In order to study the STATCOM(static synchronous compensator) for active filter functions, based on the area equivalence principle of sampling theory, the paper creates a new STATCOM control method which has equal pulse-level and unequal time-slot, establishes the mathematical model of the new control method, and derives the formulas of the inductance and capacitance of the main circuit. The new control method can make STATCOM output sinusoidal and non-sinusoidal waveform, achieve reactive power compensation and active filtering function, the inductance and capacitance calculation formulas are concise, and can be directly applied to engineering designs.
