【摘要】：為減小由于傳感器數(shù)量不足導(dǎo)致的輸電線路等值覆冰厚度計(jì)算誤差,設(shè)計(jì)了基于3組力傳感器和傾角傳感器的新型導(dǎo)線覆冰在線監(jiān)測(cè)裝置。該裝置集成了微氣象、導(dǎo)線溫度、分布式多桿塔拉力、圖像等多項(xiàng)監(jiān)測(cè)功能。建立了相應(yīng)的等值覆冰厚度力學(xué)計(jì)算模型,并將該模型與覆冰圖像處理技術(shù)相結(jié)合,給出了一種導(dǎo)線覆冰密度計(jì)算方法。新型輸電線路覆冰在線監(jiān)測(cè)裝置于2013-03在貴州電網(wǎng)220 kV線路灑紅Ⅰ回安裝運(yùn)行,2013-03-15—2013-03-18期間,該線路發(fā)生輕微覆冰,利用該技術(shù)得到等值線路覆冰平均厚度2 mm,而忽略大、小號(hào)側(cè)桿塔絕緣子串傾角和導(dǎo)線溫度的前期覆冰厚度計(jì)算模型得到的覆冰厚度均為0。結(jié)果表明該新型輸電線路導(dǎo)線覆冰在線監(jiān)測(cè)技術(shù)能夠全面、準(zhǔn)確和靈敏地監(jiān)測(cè)線路的覆冰狀況。
[Abstract]:In order to reduce the calculation error of equivalent icing thickness of transmission line caused by the shortage of sensors. Based on three groups of force sensors and inclination sensors, a new on-line monitoring device for conductor icing is designed, which integrates micrometeorology, wire temperature and distributed multi-pole tension. The corresponding mechanical calculation model of icing thickness is established, and the model is combined with the ice-coated image processing technology. In this paper, a method for calculating the ice density of conductor is presented. A new on-line monitoring device for transmission line icing is installed in Guizhou Power Grid 220 kV line sprinkling red I circuit in 2013-03. In the period of 2013-03-15-2013-03-18, the line was slightly covered with ice, and the average ice thickness of the equivalent line was obtained by using this technique, but the thickness was large. The ice thickness of insulator string inclination angle and wire temperature calculated by the model is 0. The results show that the new on-line monitoring technology for transmission line conductor icing can be comprehensive. Accurately and sensitively monitor the icing condition of the line.
