全球最大分離式半導體元件製造商的綠色永續路 威世借助研華 WISE-IoT iEMS 打造亞太區能源管理平臺

Date: 9/1/2023 12:00:00 AM

“研華與威世對於地球永續的目標追求理念一致,雙方在 ESG 的推動上都非常積極,兩家公司攜手合作,將促成企業永續經營與環境永續發展,創造威世、研華與地球的多贏格局。” 受訪人:威世半導體亞太區資深 IEHS 總監 - 蔡海

前言

在 ESG 浪潮下,所有產業皆積極推動節能減碳,希望降低能耗與碳排量,為地球永續盡一份心力。全球最大分離式半導體與無源電子元件製造商美國威世集團(Vishay)便計畫陸續在亞太區15家工廠導入研華 WISE-IoT iEMS 智慧能源管理解決方案,將設備監控、能耗管理及維護保養集中在單一平臺,更整合亞太各廠區的能源相關資料,透過集中式管理最大化節能成效,加速實現威世集團碳排減量的總體目標。

半導體廠能源管理首重資料即時呈現

威世亞太區資深 iEHS 總監 蔡海指出,威世集團很早就意識到能源管理的重要性,也在亞太部份工廠導入能源管理系統,自動搜集與分析能來源資料,並據此制定節能減排的策略和目標。然而,早期的能源管理無法呈現即時資料,得設定每天、每週或每月作為區間來統整能耗資料,之後再進行對比、分析與檢討,才能找出結果再訂出能耗改善策略,整體時程太過冗長,成效並不好。

  

「對於一年365天、7X24小時不間斷運轉的半導體工廠而言,唯有即時有效的追蹤能耗、發現異常所在,才能真正降低能源損耗,優化減碳成效,同步降低生產成本,」蔡海說,為達到這樣的目標,威世集團決定導入研華 iEMS 能源管理系統,第一階段計畫在西安、天津、惠州、高雄等工廠導入,目前在西安的應用已經正式上線並且獲得具體成效。

智慧化帶來「2 升 4 降」的管理效益

威世西安廠主要封裝生產肖特基二極體、快恢復二極體、晶閘管、MOSFET 等組件,整個工廠占地廣大,設備與能源使用的管理工程浩大。如今,藉由導入iEMS/ECOWatch 及設備管理控制系統 FMCS(Facility Management Control System),透過資料獲取、即時監測、分析與綜合診斷,在三個層面帶來效益:

  

第一、透過 iEMS/ECOWatch 即時顯示裝置的用電狀況、統計碳排放量及計算能源管理的關鍵指標(KPI),可以有效提升能源管理效益。「未來待 iEMS/ECOWatch 逐一在各廠區上線,威世還能進行工廠間的橫向對比,從中持續找到改善能源耗用的進步空間。」蔡海強調,迎合 ESG 趨勢,威世的許多客戶會提出減碳要求,而 iEMS/ECOWatch 可以較輕鬆的達到這項任務。    

第二、透過 FMCS 同步監控暖通空調、空壓機等設備的運轉狀況,以能耗與設備稼動率來計算設備運轉效率指標,從而瞭解現場機台的衰退程度,以便及早做好維護更新規劃,可避免因設備老舊而造成不必要的能耗損失,有效提升工廠設備設施效益。   

第三、提升工作效率、減少時間與人力。蔡海進一步說明,以前相關負責人從月度或年度財務報表整理出相關資料並製表,如今透過 iEMS 不僅能向客戶展示能耗管理狀況,還能自動彙集資料及產出報表,大幅減輕因應客戶稽核作業的時間和人力。   

總的來看,西安廠導入 iEMS 系統之後,明顯感受到 2 升 4 降的效益。2 升指的是設備效率和資源利用率的大幅度提升,4 降則是生產成本、設備維修成本、設備故障率及人力的大幅度降低。

2 大關鍵選擇研華作為永續夥伴

雖然目前市場上有很多能源管理解決方案,且不乏國際知名廠牌,最後威世選擇與研華合作,關鍵有以下兩個方面:   

第一,研華結合本地部署與雲端整合的系統架構。蔡海提到,其他國際大廠推出的能源管理解決方案,多是雲端整合式架構,沒有本地部署的選擇,而研華可以透過 WISE-IoT 平台進行在地部署,再採取私有雲架構集中資料,符合威世不希望將資料上到公有雲的要求。   

第二、研華 iEMS 低代碼設計,具備高度彈性,基於標準品亦額外提供專業的訂製化系統開發服務。蔡海強調,能源管理並非一成不變,隨著營運狀況、外界環境、集團節能目標等變化,能源管理 KPI 指標也會有所調整,加上威世集團內部某些制度有別於一般企業,諸多原因使得威世必須調整能源管理系統的功能,進行定制化的開發。   

然而,國際大廠的軟體研發中心大多設在歐洲或美國,訊息來來回回要耗費很多時間,如要定制化開發,可能衍生很大的成本,反觀研華有在地的工程師團隊提供支援,加上其以客戶需求為導向的企業精神,工程師皆以非常積極的態度協助解決系統建置過程中的問題,充分滿足威世的客制化需求。   

展望未來,威世將與研華進行深度的合作,持續推動亞太區工廠的廠務能源管理系統建置專案,也將導入 iEMS 的更多智慧應用,如:導入資產維護管理系統 CMMS(Computerized Maintenance Management System)做好設施的預防維護,或是利用碳資產盤查服務,簡化永續報告書的產出作業等。   

「研華與威世對於地球永續的目標追求理念一致,雙方在 ESG 的推動上都非常積極。」蔡海相信,在擁有共同的理念下,兩家公司的攜手合作,將高度優化威世亞洲區各個工廠的能源使用效率,達到降低碳排與生產成本的效益,實現企業的永續經營與環境的永續發展,創造研華、威世與地球的多贏格局。
