Abstract
The transformer is one of the equipmen for distributing electrical_energy from_mediumvoltage 20 kV to low voltage 380/220 V. Disturbance in the transformer_can_cause_Lossesso that it can disrupt the flow of electric power to consumers. Harmonics_are disturbancescaused by the operation of non-linear loads. This study aims to determine the effect of THDion power Losses and working capacity of transformers at Udayana University Student CenterBuilding with harmonics in the R phase of 10.91%, the S phase of 11.38%, and_the T phase of17.91%. The method used is to perform simulations andanalysis_with_the_results_of_harmonic measurements in Existing conditions, using an activefilter, and an active PID-based filter using the Matlab application. Very optimal results wereobtained using a PID-based active_filter with the results of R = 0.31%, S = 0.30%,_T =0.35%,_and the decrease in the working_capacity_of_the_transformer_decreased_to1%,_according _to_the_ideal_value.
变压器是将电能从20kv中压输送到380v / 220v低压的设备之一。变压器中的扰动可能会导致损耗,因此它可以中断向消费者的电力流动。谐波是由非线性负载运行引起的扰动。本研究旨在确定在R相占10.91%,S相占11.38%,T相占17.91%的情况下,乌达亚那大学学生中心大楼变压器的THDion功率损耗和工作容量的影响。所使用的方法是在现有条件下使用有源滤波器和基于有源pid的滤波器对谐波测量结果进行模拟和分析。使用基于pid的active_filter获得了非常理想的结果,R = 0.31%, S = 0.30%, t =0.35%,并且working_capacity_of_the_transformer_reduced__to_the_ideal_value降低到1%。
