| 摘要: | 本研究係針對電廠機組停機大修之排程最佳化模式進行探討。為了提供充足穏定的電力，除了線上作業的系統控制要精益求精外，而非線上作業的良好規劃，亦將影響線上調度控制的難易。 本研究的大修排程是考慮系統備轉容量、區域平衡、燃料成本、人力機具調配及最小維修工期等條件下，規劃二年內最佳之機組大修順序，以提供發電預定使用。以大修所造成營運利益損失最小為目標之另類思考模式，建立機組大修時程之數學模式，應用數學規劃電腦套裝軟體(LINGO)，以求出最佳之機組大修時程組合，並藉由實例測試來測試及驗證模式之可靠度，以作為民營業者日後之參考應用。 本研究之主要研究內容包括台灣電力公司電力系統機組大修現況檢討、機組大修排程之探討、組合規劃模式與研究流程之建立及案例研析。本研究之研究方法有文獻回顧、專家訪談及方法論，其中文獻回顧方面係就國內外相關之文獻蒐集與整理，分析探討電力系統機組大修排程問題與方法；專家訪談方面係透過與電機專家及台灣電力公司調度單位人士之訪談，討論台灣電力公司目前執行大修規劃之情況與問題所在，並定義電力系統機組大修排程之目標與限制；在方法論方面，本研究以數學規劃方法分析問題架構，並配合組合最佳化之觀念，建立以造成營運利益損失最小為單一目標之組合規劃模式，並以Microsoft之Excel應用軟體，自行撰寫模式執行檔，配合使用LINGO套裝數學規劃軟體求取最佳解。本研究以另類的思維，祈能發展出較大彈性之最佳化模式，並可直接由電腦進行大修時程規劃及修訂作業。本研究除可提供小規模機組數量之民營公司使用外，亦可適用於大規模機組數量之公營機構，也期望能提供進行規劃決策時之參考，進而提昇經營績效。 In this paper, we investigate and study an efficient optimal maintenance- scheduling model of power plants’ generators. In order to provide power enough and stably, we also have to keep an eye on the outline research except online research, because of it will influence the mobilization of power generation system. In this study, the model is to plan the maintenance- scheduling in two years via consideration of the conditions of spare capacity, area balance, fuel cost, mobility of man-power and machine, the minimum maintenance time. We propose the minimum benefits loss of power system operation as an optimal aim to set up the model, the application of mathematical programming soft (LINGO) is used for demanding the optimal solution, and verifying the reliability of model by testing an example. In this study, the major contents include present situation of the generators maintenance and maintenance scheduling of TPC power system, composition of programming model, and research of example. In this study, the method of research includes literature search, meeting and discussing with experts, methodology. For literature search, we collect and analyze the problem of maintenance scheduling model of power plants’ generators; for meeting and discussing with experts, we through the meeting and discussing with electric expert and the expert of TPC mobility unit to discuss the problem of present situation of maintenance scheduling of TPC, and define what’s the aim and constrains; In methodology, we analyze the problem structure by mathematical programming, and take the optimal composition concept, to set up the single aim of minimum benefits loss of power system operation, and we write the model formula by Excel and join the LINGO mathematical programming soft to seek for the optimal solution. In this study, we take another kind of concept and hope that the better elastic optimum model could be developed and the plan and correcting of maintenance scheduling could be executed with computer directly. This study could be used for the company which own small quantity of generators, and also could be used for the public company which own big quantity of generators, we hope that this study could be an information for policy makers. |
