The three basic reliability indices—failure rate, repair time and interruption duration per year at a load point—are important indices which are required to be obtained. It is observed that some repair time can be neglected and can be considered as the operating time. This paper presents a methodology to determine basic reliability indices accounting repair time omission. General bootstrapping and smooth bootstrapping techniques are used along with Monte Carlo simulation (MCS) to obtain various reliability indices. A case study on Roy Billinton Test System (RBTS) Bus 2 distribution system was done, and the results obtained using general and smooth bootstrapping techniques are compared.

 
 

Reliability evaluation of distribution system is very important. The reliability indices failure rate, repair time and unavailability are the basic indices which are required to be modified in order to enhance the reliability of the system. Gangel and Ringlee (1968) developed various modeling aspects for reliability evaluation of distribution system. Billinton and Gover (1975a) developed the methodology for evaluating reliability indices for transmission and distribution systems. Billinton and Grover (1975b) described the formulation of a group of simple equations which can be used to provide numerical estimates of the rates and duration of system load point failures. A cost reliability index and a cost effectiveness ratio are developed for evaluating distribution system design by Chang (1977). Wojczynski and Billinton (1985) discussed the effect of probability distributions reliability indices on interruption costs for reliability worth estimates. Analytical techniques have been used for reliability indices evaluation of distribution systems as discussed by Billinton and Allan
