| 基于DSP的鐵路MOA在線監(jiān)測(cè)研究(15 卷) |
| 英文標(biāo)題 |
| Study on MOA online detection technique in power supply of railway based DSP |
| 摘要 |
| 對(duì)鐵路電網(wǎng)中MOA 在線監(jiān)測(cè)進(jìn)行研究，在傳統(tǒng)基波測(cè)量法的基礎(chǔ)上，硬件上加入頻率自動(dòng)跟蹤電路，實(shí)時(shí)跟蹤電網(wǎng)頻率，解決FFT的頻譜泄漏問(wèn)題，軟件上小波分析解決現(xiàn)場(chǎng)干擾和去除噪聲問(wèn)題，F(xiàn)FT可方便地得到各次諧波，從而計(jì)算出測(cè)量所需的阻性泄漏電流。 |
