Analisis Pengaruh Manuver Jaringan 20 kV GI Sragen terhadap Susut Daya

The use of electricity in the community is still dependent on the electricity supply of PT. PLN (Persero), which is the only state-owned company (BUMN) that is engaged in providing up to the distribution of electricity. Due to technological developments, the industrial world, and the high increasing electicity needs in community over time, so that a good supply and distribution of electricity is needed, in order to minimize blackout and maintain customer satisfaction. This research is discuss about the effect of network maneuvering on power losses carried out by PT. PLN ULP (Customer Service Unit) Sragen. Network maneuvering is run on a 20 kV distribution network for the delegation of the transformer III load on the Sragen substation that is being maintance. Power shrinkage analysis is done by network simulation using ETAP. Simulation results used to analyze the power loss changes that occur when the network is normal and when network maneuvers are carried out. The simulation results using ETAP according to SOP number 1 and 2 transformer III work showed total power losses when the normal network network conditions were 607.5 kW and 2,361.6 kvar while total power losses when network maneuver conditions were 1,031.3 kW and 4,362 kvar. When the network maneuver conditions increase power losses by 69.76% or 423.8 kW and 2,000.4 kvar compared to when the network conditions are normal
