Desain Flux Vector Control Inverter 3 Fasa Pada Motor Induksi 1.5 HP Menggunakan Power Blockset

This paper describe Flux Vector Design Using Vector Matlab on 3 Phase Inverter when torque changes. Transient response is important things for inverter because it needs optimal torque that motor shows desire performance. This condition needs flux vector design that give V/F linear comparison in transient response. The experiment was done by simulating induction motor parameters using Matlab, the result shows : Torque supply 240 - 320 Nm, in 0.005 - 0.01s range of time

Hybrid Active Filter Untuk Meredam Resonansi Harmonisa Pada Sistem Pembangkitan Di Industri

The paper describes a hybrid active filter for reducing harmonics resonance in the industrial power generation system. The system involves a low/medium power active filter and a tuned passive filter on the 5th harmonics. The experiment result shows a prospective result that could reduce the 5th and 7th harmonics significantly

Simulasi Filter Pasif Dan Perbandingan Unjuk Kerjanya Dengan Filter Aktif Dan Filter Aktif Hibrid Dalam Meredam Harmonisa Pada Induction Furnace

This paper describe about simulation of Passive Filter in analysis to reduce harmonics that happened in a load such as vacuum casting induction furnace 9 kW, 13.8 kVA, 200V, 3 Ph, 50/60 Hz, also gives comparison with Hybrid Active Filter and Active Filter which made satisfaction result on the previous research. The best result achieved on the use of Hybrid Active Filter on %ITHD for 4.27 % and %VTHD for 3.83%, while Active Filter gave on %ITHD for 5.14 % and %VTHD for 3.82%. There are 17.23% and 0.44% lower in %VTHD and %ITHD if compared with result achieved by Passive Filter. Both of them are suited with %THD standard. But the result achieved by Hybrid active Filter gave most satisfactory value compared with Passive Filter\u27s for17.65% and 0.43% lower in %VTHD and %ITHD.. Simulation on Passive Filter produced on %ITHD for 22.37 % and %VTHD for 4.26%. In this case, %ITHD standard for applying Passive Filter could not be fulfilled

Simulasi Filter Aktif Hibrid Konfigurasi Seri-Seri Dan Unjuk Kerjanya Untuk Meredam Harmonisa Pada Beban Induction Furnace

Harmonics Filter's USAge had been widely recommended to overcome harmonics problem which occurred because of non-linear load presence in many industrial plants and manufacturing machines. On the previous research[1,2] it is obvious that both Active Filter and Hybrid Active Filter in Parallel Configuration made a satisfaction results for damping voltage and current harmonics. This paper descript in more depth on one of many types in harmonics filter named Hybrid Active Filter in Serie-Serie Configuration, thus it simulated to reduce harmonics that happened in a load such as vacuum casting induction furnace 9 kW, 13.8 kVA, 200V, 3 Ph, 50/60 Hz. The methods used still the same with the previous filter's simulated. This research (Hybrid Active Filter in Serie-Serie Configuration) produced on %ITHD for 11.86 % and %VTHD for 1.88%. In this case, both %ITHD and %VTHD are fulfilling IEEE 519

Sistem Otomatisasi Distribusi Air Menggunakan Speed Drive Inverter

Our daily need about water is absolutely essential. Therefore we need some equipments which can support to supply the water accordance with our needed. For example%2C to supply the water in hotel%2C the greater the amount of using the water then we need performance of water pump more and more to move the water from low surface to the higher. However%2C often using of pump is not comparable with our needed and the pump is often operated continually so there are some electrical power and some water that neglected. In this paper%2C the using of water pump will be controlled by speed drive inverter. Motor pump can be arranged so output rate flow of the pump that become accordance with load of using of the water. The controlling of motor is done by inverter by change the frequency%2C but automation is controlled by PLC by using limit switch as sensor of elevated at reservoir and as varian frequency input on inverter%2C also we use pressure switch as automation on-off pump with pressure method. On testing of performance of the equipments%2C obviously it shows total of efficiency of system is not very big. For arranging 35-50 Hz%2C total efficiency reaches only 14 %25
