Analisa Keandalan Sistem Distribusi 20 kV Pada Penyulang Pejangkungan DI PT PLN PASURUAN Menggunakan Metode Reliability Network Equivalent Approach

Resilience and reliability in distributing electricity are crucial and need to always be maintained in order to meet consumer needs. Several aspects that indicate the reliability of an electricity distribution system include the continuity of the available energy supply for 24 hours.
In evaluating the reliability of distribution networks, several indicators are used. One of them is SAIFI (System Average Interruption Frequency Index), which is used as a reliability indicator based on the number of disturbances that occur on average over 12 months.
Then, SAIDI (System Average Interruption Duration Index) becomes an indicator that measures the duration of interruptions experienced by customers during a 12-month period. Meanwhile, CAIDI (Customer Average Interruption Duration Index) is an index that measures the average duration of disruption experienced by consumers over 12 months.
The results of the analysis carried out on software ETAP, the RNEA method, and software have been successfully carried out. Where the analysis results for each method have different SAIFI and SAIDI numbers. The reliability of the Pejangkungan distribution system has met the specified standards, namely based on SPLN 59:1985, namely SAIDI 21.09 hours/customer/year and SAIFI 3.21 times/customer/year.
