Abstract :
This paper describes a case study on number of damages and loss of service analysis for distribution feeders in PEAC 1 (Provincial Electricity Authority Central 1) system which consists of 491 feeders from 67 substations. Theses distribution feeders are located in the Ayutthaya Province of Thailand. The number of damages and loss of service evaluations are based on an IEEE, IEC standard and ITU-T recommendations. The aim of the number of damages and loss of service analysis is to study the effect of annual number of expected damages on distribution feeders. The analysis shows that number of damages at feeder 1 Nontri substation (NSI 01) has highest to 94 times per year but the loss of service of Nontri substation has not highest to become Bangsai substation. Loss of service of Bangsai substation has highest to 0.083314 and Thammasart substation has lowest to 0.011126.
