Abstract
Prinsip utama PLTU adalah mengubah energi kimia dalam bahan bakar menjadi energi listrik. Proses konversinya memerlukan komponen utama, seperti boiler, turbin, dan generator. Boiler merupakan komponen yang berfungsi memanaskan air sehingga berubah fasanya menjadi fasa uap. Uap yang dihasilkan boiler adalah uap kering dengan tekanan dan temperatur yang tinggi (superheated steam). Salah satu bagian utama dari boiler adalah superheater. Di mana superheater berfungsi menghasilkan main steam, yaitu uap utama yang digunakan untuk memutar High Pressure Turbine. Superheater mengubah uap basah (saturated steam) menjadi uap kering (superheated steam). Uap basah dapat menyebabkan erosi pada sudu-sudu turbin sehingga uap basah harus dipanaskan lagi menjadi uap kering yang mencapai suhu 541℃. Agar temperatur uap yang masuk ke turbin dapan terjaga dengan tetap, maka operator boiler harus menjaga agar temperatur uap yang dihasilkan superheater tetap berkualitas. Spray temperature berfungsi untuk mengontrol temperatur uap di superheater agar tetap berkualitas. Kontroler yang digunakan pada control valve superheater spray adalah kontroler PI. Penulis ingin melakukan perancangan sistem pengaturan cerdas menggunakan Neuro-PID. Simulasi dilakukan menggunakan simulink pada software Matlab. Simulasi dilakukan dengan cara membandingkan respon plant pada saat sebelum dan sesudah dipasang kontroler.

The main principle of steam power plant is to convert chemical energy in fuel into electricity. The conversion process requires major components, such as boilers, turbines and generators. The boiler is a component that functions to heat water so that it changes its phase to the vapor phase. The steam produced by the boiler is dry steam with high pressure and temperature (superheated steam). One of the main parts of the boiler is the superheater. The superheater converts wet steam (saturated steam) into dry steam (superheated steam). Wet steam can cause erosion of the turbine blades so that the wet steam must be heated again to become dry steam which reaches a temperature of 541℃.. In order to keep the temperature of the steam entering the turbine constant, the boiler operator must maintain the quality of the steam produced by the superheater. Spray temperature functions to control the temperature of the steam in the superheater to maintain quality. The controller used in the superheater spray control valve is a PI controller. The author wants to design an intelligent control system using Neuro-PID. The simulation was carried out using simulink in the Matlab software. The simulation was carried out by comparing the response of the plants before and after the controller was installed.
