Main Steam

The main steam pressure control system in marine steam power plant has the characteristics of time-varying, nonlinear and strong coupling. In order to get satisfactory control effect, we propose a fuzzy immune PID controller with which we can make comprehensive utilization of advantages of artificial immune, PID and fuzzy controller. We build up mathematical model of main steam pressure control system, carry out simulation and comparison. The results prove that fuzzy immune PID controller can significantly reduce the overshoot and settling time of main steam pressure. It is more effective in main steam pressure control system than PID controller.

Main Steam

The combustion process of CFBB is a system with time-varying, nonlinear, large inertia and time delay. Therefore the control effects of traditional PID control system in the CFBB plant are not satisfactory , especially the overshoot of the main steam pressure control system is very big, and the adjustment time is too long. To improve the performance of the main steam pressure control system, ADRC technology was used . The disturbed signal was added in the different operating conditions, the testing results indicated that the ADRC main steam pressure control system had more excellent performance than the convention PID method.

Pressure Control System

This paper presents the results obtained from the IBE-CNC/DAQ-090827 project, conducted by the company “Titania Servicios Tecnolo´gicos, S.L.” in collaboration with the “Instituto de Seguridad Industrial, Radiofi´sica y Medioambiental” (ISIRYM), in the “Universidad Polite´cnica de Valencia”, for the company “Iberdrola Generacio´n S.A”. The objective is the acquisition of the pressure sensor signal and the measurement at points C85 and N32 from the cabin of the Turbine Control System in Cofrentes Nuclear Power Plant. With the study of previous data, one can obtain the Bode plot of the crossed signals as requested in the technical specification IM 0191 I. Frequency response (i.e. how the system varies its gain and offset depending on the frequency) defines the dynamics.

Industrial boiler steam pressure is an important measure of boiler normal operation. Since there is delay and inertial part, single-loop PID control is difficult to achieve good dynamic characteristics. By analyzing the characteristics of the steam pressure controlled object, this paper presents a fuzzy adaptive PID control based on the cascade control system. Finally, in order to analyze the effect of the control system, mathematical model was constructed by MATLAB simulation to compare fuzzy adaptive PID cascade control with conventional PID control. The results prove that the former has a good control effect.

Demineralized Water

Pada penelitian ini dibuat simulasi tentang sistem kendali water treatment pada Pembangkit Listrik Tenaga Uap Sebalang unit 5 & 6 Lampung Selatan. Pembangkit Listrik Tenaga Uap bekerja dengan memanfaatkan energi tekanan uap dari proses perebusan air demineral air laut oleh batu bara untuk menggerakkan turbin dan generator yang akhirnya menghasilkan listrik. Bahan utama penghasil uap ini adalah air laut yang tentu saja memiliki kandungan kimia yang masih harus diolah dengan baik sehingga dapat menghasilkan uap yang tidak merusak logam-logam, khususnya kandungan garam yang sangat konduktif dan bersifat korosif. Oleh karena itu, sangat diperlukan suatu metode pengolahan air laut menjadi air demineral yang layak dijadikan uap bagi turbin yaitu metode pentreatmenan air (water treatment). In this research the simulation is made of water treatment control system on Steam Power Plant Unit 5 & 6 Sebalang, South Lampung. Steam Power Plant works by using the energy of the steam pressure by boiling demineralized sea water using coal to rotate a turbine and a generator, which is finally produces electricity. The main ingredient to produce this steam is sea water which still has chemical composition, which needs to be proccessed well, so the steam which is produced does not ruin metal, especially content of slat which is very conductive and corrosive. Therefore a method of proccessing salt water to be a proper demineralized water steam for generator is needed, which is called as water treatment method.
