摘要

摘要 近年來台灣區域性限電 (Power Rationing) 頻率升高，
許多用電大戶積極配合台電公司啟動廠內緊急發電機
1. 前言
(Emergency Generator) 進行發電，協助台電分擔電網
1.1 台灣的電力供應及限電狀況分析 負荷，渡過電力危急時刻。因此在各用電大戶的緊急發電
機運轉需求未來可能逐漸由「備用」轉為「常用」的趨勢
1.2 緊急發電機的重要性
下，提升發電機的可靠度並避免跳機影響負載為一大重要
1.3 本研究方向簡介 議題。本研究以竹科 F8 設置之動態不斷電系統 (Dynamic
Uninterruptible Power System, DUPS) 為例，探討當廠
2. 文獻探討
區配合台電限電運轉時，DUPS 發電機的柴油引擎 (Diesel
2.1 動態不斷電系統的原理介紹 Engine) 散熱效果，並進一步分析散熱器、冷卻水、管壁
結晶等因素如何影響熱交換效率，以提升緊急發電機運轉
2.2 關於 DUPS 柴油引擎的介紹
可靠度。
2.3 發電機冷卻水溫度的流力分析

and avoiding tripping and affecting the load are the
作者介紹 research directions of this paper. This study takes the
Dynamic Uninterruptible Power System(DUPS) of F8
as an example to discuss the heat dissipation effect of
the diesel engine(Diesel Engine) of the DUPS generator
when the factory area cooperates with Taipower�s
power outage operation, and further analyzes How
factors such as radiator, cooling water, and tube
wall crystallization affect heat exchange efficiency
to improve the operational reliability of emergency
generators.
