| 摘 要： | 针对UPFC的输出电压中谐波含量过高的问题，依据SPWM控制理论，采用不对称规则采样算法，并利用TMS320 F240DSP的高速运算能力，提出了实时在线地消除逆变电路输出电压中谐波含量的硬件方法，实现了其在UPFC模型上的试验研究，仿真结果证明，由这种新硬件装置得到的逆变输出结果显著提高了逆变输出的准确度。

| Abstract: | aimed at the question of high harmonic content in output voltage in UPFC and according to the SPWM control theory, we adopt the arithmetic of asymmetric regular sampling algorithmic and utilize the PWM creating and outputting technology and its high speed operational capability in TMS320F240 DSP chip. We put forward the new hardware mode to eliminate the harmonic wave of inverter in real time and realize the SPWM control technique of UPFC experimentation devices based on TMS320F240DSP.The emulation conclusion shows the control by the new hardware technique can improve the accuracy of the invert output. |
