ANALISIS TATA LETAK RECLOSER MENGGUNAKAN METODE PENELETIAN STATISTIKA BEBAN DAN POPULASI GUNA MEMAKSIMALKAN KINERJA SISTEM

Abstract

Disturbance at PT. PLN (Persero) Rayon Sidayu Area Gresik Distribution East Java is quite diverse, most of the disturbance that occurred was temporary temporary, the cause is not known and to minimize the disturbance is widely used automatic cover (recloser) on the electricity distribution network. The placement of the recloser is only based on a safe distance without consideration of the load and the customer population and calculation of the layou t for the determination of the location that can maximize the system performance. By knowing the burden and the customer population it will be able to know how many losses and the number of customers who will experience a disruption when the recloser has failed function due to improper layout, load and customer population can also be a variable to calculate SAIFI value. One parameter of failure (the extent of failure or blackout to the customer) in the electrical world is the value of SAIFI (System Average Interruption Frequency Index). Higher values indicate an increasing rate of failure. In this analysis there are 3 points that counted SAIFInya value that is point 19 with SAIFI value 15.1, point 18 with SAIFI value 61,7 and point 12 with value SAIFI 137,2. from the calculation of each point can get the result of SAIFI minimum disturbance index that is at point 19.
