摘要
在這篇論文中，我們提出一個對SCADA監控系統可靠度和故障模式進行分析的方法，降低資料傳遞不穩定性對監控系統的影響，並找出系統可靠度盲點加以研討。 在我所提出的監控系統中，符合可靠度與故障影響模式來要求，運用回授時間模擬技術來規劃資料傳輸延遲模式，並估測SCADA回授時間。藉由SCADA回授時間及監控系統效能要求等資訊，故障模式影響分析Failure Mode and Effects (FMEA)技術被使用來進行系統元件之連結性分析，決定SCADA在不同元件傳輸架構下之執行率。考慮監控系統元件之可靠度研討結果較未考慮效能要求之可靠度研討結果為保留，且故障率較偏高或數量較多的元件對系統可靠度影響層面較大。 在這篇論文中，我們將提出以下的貢獻： 提出之分析模式可提供電力公司未來在設計類似系統時之參考。針對未考慮效能要求與考慮效能要求之SCADA系統做一些效能上的客觀評估，然而在不同的SCADA系統功能上，其模擬結果也不盡相同，再加上如果使用在不同的系統架構，所產生的結果也會不同。由這些結果可以提供輸電自動化設計的參考。

In this thesis, we propose a method that allows the simultaneous analysis of the systematic reliability and efficiency of SCADA (Supervisory Control and Data Acquisition).The purpose in order to reduce the impact of unreliable or incorrect data input on the system, and to further pinpoint the vulnerabilities in system reliability. To ensure the requirements of systems reliability and efficiency, this proposed method employed the technology of discrete time simulation to establish the model of delayed data transfer and to estimate the response time of SCADA function. The SCADA function response time and the system efficiency requirements are then incorporated into the Failure Mode and Effects (FMEA) to perform the correlation analysis of the system elements, and eventually determine the usability of the SCADA under various frameworks of data transfer. Testing results shows that the reliability of the system in which the requirement of efficiency is taken into consideration is more conservative than that of the system in which the efficiency requirement is not considered. The impacts of relatively higher fault rates and higher numbers of elements on system reliability were greater. The major contribution of our thesis lies on the objective assessment for SCADA systems with performance consideration requested or without. On different SCADA systems, the results of the simulation are different as well. If the simulations apply to different system structures, the outcome is different. The results can be used for the design on an automatic electricity transport references. The proposed model in this report will hopefully provide references for assisting with designs of the similar system by power companies in the future.
