通信機房用電契約配置探討
Investigation on Power Demend Contract Arrangement for Communication Base Stations
摘要
中文摘要 近年來因經濟成長及生活水準提昇，造成全球能源短缺，影響到台灣電力公司的發電成本，進而逐步調漲電費。對電信交換機房而言，無疑是一大筆的用電成本增加。因為通信設備，必須維持全年365天，每天24小時，不能停止運轉；所以，如何在無重大負載變化前提下，選擇有利的計費方式是一重要的研究課題。 本文以中華電信公司的通信機房用電模式來探討在複雜的台灣電力公司電價表中，以相同的用電情況下，如何利用簡易的評估表來選擇各種不同的用電種類，來判斷最佳的用電計費方式。因為在相同的用電情況，依與台灣電力公司所訂定之不同用電方式，將會有著不同的計費方式，其結果也會造成電費不相同。此外，本文嘗試著以幾個電信機房進行實證研究來比較其電費差別，以求得最佳用電模式。 本文研究結果，顯示在穩定無重大負載變化的通信機房在高壓用電的部份應選擇三段式時間電價計費，而在表燈用電部份應考慮其用電度數判斷後是否使用表燈時間電價，最佳契約容量的部份經過評估和轉移之後還能有節省用電成本的空間。本文證明通信機房應隨時注意用電管理的重要，並進而可供具有相同負載特性的用戶來做為評估使用的參考。

ABSTRACT In recent years, the increase of economy growth and living standard is accompanied by global energy shortage. Besides, this fact has influenced the power generation cost of Taiwan Power Company and contributed to the gradually raising of the electricity charges. For the telecommunications PBX (Private Branch Exchange) center, this is undoubtedly a big sum of increment in the power consumption cost because the telecommunications facility is required to maintain its operation around the clock for 365 days per year without ceasing the operation. Therefore, methods to select the beneficial cost calculation without encountering major variation in the electricity load are important. In this research, the power consumption model of telecommunications control center in Chunghwa Telecom Co. is adopted for the investigation. Under the condition with the same power consumption, the research focuses on utilizing a simplified analysis table to choose the different power consumption categories in the complicated electricity rate tables and determine the optimal cost calculation method for power consumption. In identical electricity consumption under various pricing policies given by Taiwan Power Company, it will have different electricity expense. Furthermore, the research implements empirical studies to compare the differences of electricity bills between several telecommunications control rooms. The results prove that three-phase service should be adopted for calculation of high voltage power consumption in telecommunications control centers which are stable and have no major variation in the electricity loads. On the other hand, the telecommunication equipment rooms with meter rate lighting service should consider the power consumption and determine if the meter rate lighting service is appropriate. After assessing and adjusting for the optimal contract capacity, there are more rooms for reduction in power consumption cost. In summary, the telecommunication control centers should pay attention to the power consumption management at anytime. Moreover, this research can contribute by providing the reference as an assessment tool of reduction in power consumption for specific users with the similar electricity load.
