配電饋線自動化系統之案例探討及其效益分析

Abstract

提供完善的電力品質與安全的系統運轉是電力公司基本的責任與目標。當配電線路故障時如何迅速找出故障點並予以隔離及修復，加速恢復供電，減少對用戶之影響與損失，更是電力公司長期努力之課題。因此藉由配電系統自動化來改善供電可靠度，已成為現代配電系統發展研究中主要方向之一。配電自動化的效益不僅包括人力與停電成本降低的有形效益，也包括提昇客戶滿意度的無形效益。 在配電自動化系統中，配電饋線自動化在配電系統運轉調度上對於縮短停電時間、減少停電範圍、提高供電可靠度有最直接的效果。本研究藉由蒐集國內外配電自動化系統相關文獻及案例進行研討，並以實際配電饋線自動化系統個案，探討建置時之規劃策略、系統功能架構，以及運轉之效益分析。本研究以實際運轉中之配電饋線自動化系統為研究對象，並提出從提高供電可靠度、增加電費收入、節省人力成本、減少缺電成本損失等方面，予以量化評估其效益。其成果將更具實用性，並可將此成果做為電力業者配電饋線自動化系統建置及擴充時效益評估之參考。

Providing reliable and high-quality electricity to people is an essential objective for all power companies. The distribution feeder automation system can be utilized by power companies to improve the reliability of power supply and thus enhance customers’ satisfaction. In addition to the improvement on system reliability, deployment of such a system can also result in the reduction of operational cost. This master thesis provides a literature review on this subject, describes the architecture and functions of the automation system, and analyzes benefit and cost for deployment of the system. Quantitative assessments of the benefit include improved reliability, increased revenue, reduced human cost and outage loss. An exemplary case is described and analyzed in detail such that the benefit and cost can be well understood. Guidelines are given for future adoption of the system.
