The output value of<br />the voltage loop is also normalized to be limited between 48000 and –48000. Suppose that<br />the maximum positive value of the primary current is 130A and the attenuation coefficient<br />is 22 / 2000 = 0.011, then the original AD conversion result is 130 × 0.011 × 4096 / 5 = 1171 .<br />Therefore all the AD conversion results of the primary current should be multiplied by<br />48000 /1171 = 41 for normalization in order to be limited within the output range of voltage<br />loop.<br />1.这篇文档假设了电压环经过PI补偿后输出范围是48000到负的48000,这个是怎么搞出来的?<br /> |
