Analisis Rugi Daya Saat Manuver Jaringan dengan Etap Power Station 12.6

At present, electricity is a primary need for every human being. Most of the equipment used in everyday life always requires electricity. PT. PLN (Persero) as the party that provides and distributes electricity, must always meet customer needs and innovate. The electricity distribution system is the most disturbed thing. The subject of this research is to examine the condition of power losses when carried out maintenance with ETAP Power Station 12.6. Feeders Nguntoronadi 2 and Wonogiri 7 will be examined for power losses because maintenance is carried out in Nguntoronadi 2. The required data is obtained from PLN (Persero) Wonogiri District. Single line diagram is made, then simulated with ETAP Power Station 12.6 to facilitate analysis. The simulation results obtained are power losses under normal conditions of 1000 watts and 872.7 kVar. And when the power loss maneuver is 600 watts and 535.1 kVar. The difference between the calculation of the power loss on normal conditions and when maneuvering is 40% active power and 38.68% reactive power. Network maneuvering can be done by Wonogiri 7. When the power loss maneuver decreases 40%. Suggestion that the power loss can be suppressed by the procedure for maintenance time not more than 1 day, if more than 1 day then many electrical devices are damaged
