การประเมินระบบไฟฟ้าบนพื้นฐานของดัชนีความเชื่อถือได้และอัตราค่าพลังงานไฟฟ้าดับ / สัมประสิทธิ์ ประสพสุข = Electrical system evaluation based on reliability indices and interrupted energy rates / Samprasit Prasopsuk
This thesis emphasizes on an evaluation of electrical system by using reliability indices and interrupted energy rates. The evaluated systems are the high reliable systems of industrial plant. The thesis applied an index evaluation by using an analytical method with minimal cut set technique. This method is easy for programming and provides accuracy results. The evaluated results show the quantitative reliability of load points in the system e.g. failure rate, annual outage time and availability, etc. and the quantitative reliability of the system e.g. SAIFI, SAIDI and CAIDI, etc. In addition, the results show the actual outage cost represented as interrupted energy rates of the critical load point calculated by contingency enumeration method (CEM) and basic indices method (BIM) and interrupted energy rates of the system calculated by system indices method (SIM). These results are used to analyze and compare systems by considering including the cost. This analysis and comparison help guiding for the system design and assessing the worth of investment.
