Analysis of Electric Power Consumption on Business and Economic Executive Class Trains at PT KAI (Persero) UPT Depo Train Class B Medan

Abstract

Maintenance or well-scheduled maintenance of Passenger trains, including maintenance and overcoming train air conditioning problems, maintenance of lights and other comfort support equipment such as LCD TVs and fans, PT Kereta Api Indonesia formed the Facilities Maintenance Division, in this case the Passenger Train Depot owned by each Operating Region (DAOP). the purpose of this research is to analyze the power consumption on passenger trains so that it can be done for the generating system to be assembled with a maximum amount. In this study, calculations were made about the total power consumption that must be borne by passenger trains, measuring daily loads in each class of trains, knowing the power consumption capacity factor according to the amount of load borne by the train. From the results of measurements and calculations carried out, the executive class train generator has a capacity of 500kVA, has a nominal current of 759.68A. The maximum demand of all load components installed in one executive class carriage is 17.93kW, 29.471kVA, and 61.844A and the maximum demand of all load components installed in one executive class restoration carriage is 15.86kW, 26.504kVA, and 48.356A, Translated with DeepLcom (free version). The business class train generator with a capacity of 150kVA with a nominal current of the business class generator generator is 227.9A, the maximum requirement of all installed load components in one business class carriage is 2.45kW, 3.532kVA, and 16.055A. The maximum requirements of all load components installed in one business and economy class restoration car are 1.141kW, 1.823kVA, and 8.283A. For the capacity of the economy class train generator with a capacity of 50kVA, the nominal current of the executive class generator is 75.96A, the maximum requirement of all installed load components in one economy class carriage is 0.856kW, 1.351kVA, and 6.141A.Translated with DeepL.com (free version)
