Analisis Pengaruh Variasi Pembebanan Terhadap Kinerja Motor Primary Air Fan 3 Fasa, 6 Kv Unit 2 Di PLTU Teluk Sirih

Abstract

The 3 phase, 6 kV PAF motor is one of the induction motors used at the Teluk Sirih PLTU to produce air pressure that enters the combustion chamber (boiler). In Unit 2 of the Teluk Sirih PLTU there are 2 PAF motors. PAF motors experience changes in daily load in motor performance such as: input power, reactive power, output power and motor torque. The aim of this research is to study and see the performance of a 3-phase, 6 kV PAF motor regarding daily load changes during the generator performance test. From the analysis results it was found that as the generator load increases, the input power, output power and motor torque also increase, where at 16.00 the generator load is 100 MW for PAF A, the highest input power is 961.2918 kW, output power is 915.1498 kW, reactive power is 459 .2839 KVAR and motor torque of 5864.165 Nm.
