ABSTRAK Sebagai alat transportasi yang dapat menampung penumpang lebih banyak, Kereta Rel Listrik (KRL) harus memilki sistem kerja yang baik guna menunjang kebutuhan akan sarana transportasi massal di Indonesia. Namun, akibat penggunaan beban non linier pada sistem kerja Kereta Rel Listrik dapat menimbulkan masalah dalam sistem yaitu menyebabkan harmonisa yang dapat mengakibatkan penurunan kualitas daya pada sistem. Salah satu contohnya adalah converter yang terdapat pada sistem Kereta Rel Listrik Jogyakarta- Solo yang dapat menghasilkan distorsi harmonisa sehingga peralatan dapat menjadi lebih panas bahkan dapat mengalami kerusakan. Oleh karena itu untuk mengetahui besarnya nilai harmonisa pada sistem tersebut diperlukan analisa serta merancang suatu alat guna mengatasi permasalahan harmonisa tersebut. Untuk mengatasi masalah harmonisa yang terjadi pada sistem dipasang peralatan berupa filter pasif jenis singel tuned filter.Pemasangan filter pasif ini dipasang pada bus beban converter, transformator serta motor untuk mereduksi harmonik orde 5. Hasil simulasi menunjukkan pemasangan singel tuned filter dapat menurunkan nilai arus maupun tegangan harmonisa Setelah dipasang filter, arus bus converter naik 0,03%, dan tegangan turun sebesar 8%, bus transformator arus turun 0,3%, serta tegangan turun 44,71% dan arus bus beban motor turun 19,85% sedangkan tegangan turun 43,91%. Kata kunci : Converter, Distorsi Harmonisa, singel tuned filter. ABSTRACT As a means of transportation that can accommodate more passengers, Electrical Railway (KRL) needs to have a good working system to support the need for mass transportation in Indonesia. However, due to the use of non-linear load on Electrical Railway systems work can cause problems in the system that is causing the harmonics that can lead to decreased quality of power on the system. One example is contained in the converter Electrical Railway system Jogyakarta-Solo. can produce harmonic distortion that equipment can be more heat can even be damaged. Therefore, to determine the value of harmonics in the system is required analysis and design a tool to overcome the problems of the harmonics. To overcome the problem of harmonics that occur on the system is installed the equipment in the form of a passive filter tuned filter. Single type of passive filter is installed in the bus load converters, transformers and motors to reduce the harmonic order of 5. The simulation results show the installation of the single tuned filter can reduce the value of current and voltage Once installed filter harmonics, the current on bus of converter up 0.03%, and a voltage down 8%, a bus of the transformer,the current down 0.3%, and 44.71% of voltage down and the current on bus load of the motor down 19.85% while voltage down 43.91%. Keywords : Converter, harmonic distortion, singel tuned filter.
