ABSTRAK

Pada saat ini kondisi di Lab.Steam power plant PPNS mengalami banyak problem yaitu salah adalah problem pada turbin yang mencangkup diantaranya Over speed Adjusment steam valve Performance parameter Rpm-meter. Kita mengatasi problem pada turbin berdasarkan adanya ketidak setabilan pada kerja turbin. Yang dalunya turbin berkerja secara stabil karena putarannya pada turbin dapat di control dengan Gavernor namun dengan berjalannya usia lebih dari 20 tahun berada di Lab.Steam power plant PPNS Gavernor mengalami kerusakan sehingga kerja turbin tidak bisa stabil. Dulu kecepatan putaran pada turbin dapat di control dengan performance parameter Rpm-meter bisa menunjukkan sampai 4000Rpm bila parameter Rpm menunjukkan angka 4000Rpm turbin akan mengalami Trip tapi pada saat sekarang parameter Rpm-meter hanya bisa menunjukkan angka 2500-3000Rpm bila lebih dari 3000Rpm parameter Rpm-meter tidak dapat menunjukkan angka atau tidak dapat mendeteksi kecepatan putaran pada turbin. Oleh karena itu performance parameter tidak dapat bekerja secara akurat dan tidak bisa mengalami tripping. Dengan latar belakang dan pertimbangan tersebut maka penulis mencoba menawarkan suatu solusi membuat adjustmen steam valve kami menggunakan motor 1Phasa yang diggunakn untuk memutar valve secara otomatis sehingga tidak manual saat uap masuk pada turbin system proteksi over speed dan porformance parameter Rpm-meter yang berguna untuk mendeteksi putaran kecepatan pada turbin yang dibantu dengan sensor kecepatan dan dicontrol semua dengan rangkaian mikrocontroller ATMEGA 8


ABSTRACT

At this moment the conditions in PPNS Lab.Steam power plant experience is one of many problems is a problem in the turbine of which includes Over speed Adjustment steam valve Performance parameters Rpm-meters. We solve problems of the turbine based on a lack of work setabilan turbine. Dalunya turbine which works on an even keel for the turbine spins can be in control with Gavernor but with the passage over the age of 20 years in power plant Lab.Steam PPNS Gavernor so damaged turbine work cant be stable. Once the turbine rotational speed can be in control with performance-meter Rpm parameters can show up 4000Rpm if the parameter indicates the number Rpm 4000Rpm Trip turbine will experience but at present Rpm-meter parameters can only show numbers 2500-3000Rpm when more than 3000Rpm Rpmmeter parameters cant show numbers or cant detect the speed of rotation of the turbine. Therefore the performance parameters cant work accurately and cant experience tripping With this background and these considerations the author tries to offer a solution where we make our adjustmen steam valve using the 1Phasa motor to rotate the valve use automatically so no manual entry in the steam turbine over-speed protection system and parameters porformance-meter Rpm useful for detecting rotation speed of the turbine speed sensor assisted with we control all of the circuit mikrocontroller ATMEGA 8
