Abstract

Sistem pembangkit tenaga listrik berfungsi untuk membangkitkan energi listrik melalui berbagai macam komponen dan peralatan pendukung. Salah satu pembangkit listrik yaitu pembangkit listrik tenaga uap. Bagian utama dari pembangkit listrik tenaga uap yaitu governor, turbin uap dan generator uap. Frekuensi dari pembangkit listrik tersebut harus dijaga pada nilai standar 50 Hz untuk kehandalan dari sistem kelistrikan. Penelitian ini bertujuan mengontrol frekuensi energi listrik menggunakan sistem Load Frequency Control dengan metode Fuzzy-PID, yang memantau dan mengukur frekuensi sistem secara terus-menerus. Sistem ini memiliki peranan penting dalam meningkatkan efisiensi dari daya yang dibangkitkan meskipun terdapat beban pada sistem tersebut. Jika daya yang dibangkitkan dalam sistem lebih kecil dari beban yang diminta, maka frekuensi akan turun. Sehingga diperlukannya sistem Load Frequency Control. Pada penelitian ini dilakukan perancangan sistem Load Frequency Control pada secondary control loop dari pembangkit listrik tersebut. dari hasil pengujian menunjukkan bahwa penggunaan kontroller Fuzzy-PID pada sistem Load Frequency Control efektif dalam mengurangi error frekuensi dan menjaga stabilitas sistem. Hasil pengujian menggunakan kontroler Fuzzy-PID menunjukkan hasil ketika nilai daya aktif yang dibutuhkan oleh beban seimbang dengan daya aktif yang dibangkitkan oleh generator frekuensi stabil pada 50 Hz dan error steady state 0%. Saat beban dinaikkan 5 MW, frekuensi menurun menjadi 49,92 Hz dengan error steady state 0,08% dan settling time 39 detik. Ketika beban diturunkan 5 MW, frekuensi meningkat menjadi 50,07 Hz dengan error steady state 0,07% dan settling time 30 detik. Saat daya kembali seimbang, frekuensi stabil pada 50 Hz dengan error steady state 0% dan settling time 70 detik.

The power generation system functions to generate electrical energy through various components and supporting equipment supporting equipment. One of the power plants is a steam power plant. Part The main parts of a steam power plant are the governor, steam turbine and steam generator. steam generator. The frequency of the power plant must be maintained at standard value of 50 Hz for the reliability of the electrical system. This research aims to control the frequency of electrical energy using the Load Frequency Control system with Fuzzy-PID method, which monitors and measures the system frequency continuously. The system This system has an important role in increasing the efficiency of the power that is generated even though there is a load on the system. If the power generated in the system is less than the requested load, then the frequency will drop. will drop. So that the Load Frequency Control system is needed. In this research This research is carried out to design a Load Frequency Control system in the secondary control loop of the power plant. from the test results show that the use of Fuzzy-PID controllers in the Load Frequency Control system. on the Load Frequency Control system system is effective in reducing frequency errors and maintaining system stability. The test results using the Fuzzy-PID controller show the results when the active power value required by the load is balanced with the active power generated by the generator, the frequency is stable at 50 Hz and the steady state error is 0%. When the load is increased by 5 MW, the frequency decreases to 49.92 Hz with a steady state error of 0.08% and a settling time of 39 seconds. When the load was decreased by 5 MW, the frequency increased to 50.07 Hz with a steady state error of 0.07% and a settling time of 30 seconds. When the power returned to balance, the frequency stabilised at 50 Hz with a steady state error of 0% and a settling time of 70 seconds.
