Abstract

Salah satu jenis pembangkit yang banyak di gunakan berdasarkan data kementerian ESDM 2016 adalah pembangkit listrik tenaga uap (PLTU) dengan persentase sebesar 40% dari total pembangkit di Indonesia. . Salah satu produsen listrik yang menggunakan jenis pembangkit listrik tenaga uap adalah PT Indonesia Power UJP Jabar 2 Pelabuhan Ratu memiliki kapasitas 350 MW . Daya tersebut dihasilkan melalui tiga turbin yang dipasang satu poros, yaitu yang terdiri dari HP (High Pressure), IP (Intermediate Pressure),dan LP (Low Pressure). Pada unit pembangkit tiga tersebut digunakan 2 jenis sistem feedwater heater yaitu dengan susunan 7 closed feedwater heater dan 1 open feedwater heater. High pressure heater (HPH) berfungsi untuk meningkatkan temperatur air yang akan dipanaskan di dalam boiler sehingga energi yang dibutuhkan oleh boiler lebih sedikit dibandingkan tanpa HPH. Kondisi HPH sering menghadapi masalah sehingga harus tidak dioperasikan karena mengalami perbaikan. Dalam hal ini diperlukan studi lebih lanjut untuk mengetahui pengaruh perubahan beban dan operasi HPH terhadap performa pembangkit.
Penelitian mengenai pengaruh operasi high pressure heater terhadap performa pembangkit ini dilakukan dengan perhitungan melalui software cycle-tempo. Perhitungan software cycle-tempo dilakukan dengan menggunakan data heat balance dari pembangkit. Pemodelan pembangkit dilakukan didalam software cycle-tempo sehingga dapat dilakukan variasi pembebanan pada turbin uap dalam cycle tempo sebesar 50%; 75% dan 100% , selanjutnya dari variasi pembebanan dilakukan empat kondisi operasi HPH.
Hasil penelitian yang telah didapatkan oleh software cycle-tempo untuk kondisi eksisting pada beban 100% dengan heat rate sebesar 10052.85 Kj/kWh dan penggunaan daya 11692.68 kW, untuk beban 75% dengan heat rate sebesar 10132.57 Kj/kWh dan penggunaan daya 8813.65 kW , beban 50% dengan heat rate sebesar 11341.33Kj/kWh dan penggunaan daya 6004.12 kW dan Penelitian ini membandingkan bahwa kondisi pada software cycle-tempo dengan kondisi aktual berbeda dimana pada beban 100%,75%, dan 50% menjelaskan bahwa prosentase losses sebesar 0.11%, 0.032%, dan 0.15% .Kondisi eksisting dalam software cycle-tempo ini mempunyai heat rate minimum diantara kondisi variasi yang lain.

One type of power plant that is widely used based on 2016 ESDM ministry data is a steam power plant (PLTU) with a percentage of 40% of the total power plant in Indonesia. One of the producers of electricity that uses this type of steam power plant is PT Indonesia Power UJP Jabar 2 Pelabuhan Ratu has a capacity of 350 MW. The power is generated through three turbines that are installed in one shaft, which consist of HP (High Pressure), IP (Medium Pressure), and LP (Low Pressure). In this three generation unit, two types of feed water heating systems are used, namely the arrangement of 7 closed feed water heaters and 1 open feed water heater. High-pressure heaters (HPH) function to increase the temperature of the air to be heated inside the boiler so that the energy needed by the boiler is less than the HPH. Repairing the HPH problem that must be repaired. In this case, a further studio is needed to determine the effect of HPH load and operation on development performance.
Research on the effect of high pressure heating operations on generator performance is done by calculation through cycle-tempo software. Calculation of cycle-tempo software is done by using heat balance data from the generator. Development modeling is carried out in the software cycle so that variations in loading on a steam turbine can be carried out in a cycle of 50%; 75% and 100%, then from variations in loading carried out empathic operation of the HPH.
The results obtained by the software cycle for the existing conditions at 100% load with a heat level of 10052.85 Kj / kWh and the use of power 11692.68 kW, for a load of 75% with a heat level of 10132.57 Kj / kWh and power usage 8813.65 kW, 50% capacity with a heat rate of 11341.33Kj / kWh and power usage of 6004.12 kW and this study compares the requirements in the software cycle with actual differences in loads of 100%, 75%, and 50% explaining the percentage of losses of 0.11%, 0.032%, and 0.15%. The contents in this tempo-cycle software have a minimum heat level for all other variations.
