中文摘要 | 架空配電線路被覆化,不但能有效保障人民及其他動物生命之安全,更能提升配電系統之供電可靠度。惟國內架空之XLPE風雨線被覆方式使用20多年以來,其被覆材料、老化程度、相關法規及保護方式均需進一步探討。國外架空配電系統線路之被覆化亦相當普遍,除使用不同於XLPE之被覆材料外,電線型式,裝桿方式、施工方式及所使用之裝桿材料隨各國地理條件、運轉習慣及系統要求之不同而有所差異。為了解XLPE風雨線的老化程度,透過對全國各不同使用條件及年限之地區進行取樣並實施電氣與物理試驗。目前我國於安全間距上對XLPE風雨線之要求等同於裸線,本研究已蒐集如NESC、JEAC等國際法規之要求,並一併探討國外電業之現況規定。被覆化架空線路之保護係世界各國電業所面臨之共同難題,本研究除了解最新國外架空電線使用趨勢、材料使用現況、裝桿施工方法、電線老化程度、饋線保護方式及安全距離要求外,亦可提供臺電將來架空配電線路更新及改進之參考。本研究亦針對已商業化之高阻抗故障保護電驛測試其性能是否能滿足臺電之要求,並研發以小波理論為基礎結合神經網路功能之智慧型高阻抗故障保護電驛,希望能徹底解決長期以來交連PE風雨線保護上之困境。 |
英文摘要 | The overland covered conductors used in distribution system not only can enhance the protection of humans and animals life but also promote the reliability of electricity power supply. The overhead XLPE covered conductors have been applied in Taipower (TPC) for more than twenty years and therefore the material of covering, deterioration of aging, type of installation, operation situation and applicable standards or regulations need to be further explored. In foreign countries, the covered wire used to replace the bare conductor as aerial lines is very popular. This research surveys the difference among covering polymeric insulating materials, type of pole, way of installation and materials of support in several utilities. To understand the deterioration of XPE covered aerial lines, the electrical and physical tests of sample conductors collected from numerous areas with various operating and usage conditions have been conducted, according to international codes and standards. At present, the clearance requirements of XLPE covered line in TPC are same as bare line. Hence, the standards like NESC, JEAC and similar regulations in other utilities have been further reviewed. The HIF protection of covered aerial line, is a common problem for worldwide utilities. Regarding to HIF protection of aerial lines, there are two approaches to perform. One is testing the commercially available relay. The other is developing a novel intelligent relay which is combined wavelet transforms theory with neural networks to solve the aerical lines HIF problems. Finally, the newly developing trend in the world including covered aerial lines, covered materials, pole installation method, line deterioration, safety clearance and line protection will be well explored. This can be an important issue for TPC when they renew or newly install their overhead distribution systems. |
