2、的等值電路參數(shù)。在上述基礎(chǔ)上，系統(tǒng)地、定量地對(duì)滄州地區(qū)電網(wǎng)上的諧波分量進(jìn)行分析、計(jì)算，為電網(wǎng)諧波治理提供準(zhǔn)確可靠數(shù)據(jù)。根據(jù)計(jì)算結(jié)果，對(duì)滄州電網(wǎng)電能質(zhì)量諧波監(jiān)測(cè)系統(tǒng)進(jìn)行研究，分析了運(yùn)行中對(duì)電網(wǎng)產(chǎn)生的作用，為滄州電網(wǎng)進(jìn)行諧波全面治理打下了基礎(chǔ)。關(guān)鍵詞：滄州電網(wǎng)，供電質(zhì)量，擾動(dòng)性負(fù)荷，諧波監(jiān)測(cè)ABSTRACT’IheCangzhouelectricalnetworkisinsouthofHebeinetterminalThesystemisr
