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.

Penelitian ini dilakukan bertujuan untuk mengetahui adanya proses pengolahan air dan pengendalian limbah di pembangkit listrik tenaga uap (PLTU) Desa Tubanan Kecamatan Kembang Kabupaten Jepara. Penelitian ini dilakukan dengan metode kepustakaan. PLTU yang dibangun di tepi laut menggunakan air laut sebagai sumber airnya. Proses yang dilakukan dalam pengolahan air ini, antara lain adalah: 1) Destilasi, 2) Demineraliasi, 3) Kondensasi, dan 4) Instalasi Pengolahan Air. Kemudian dalam melakukan pengendalian limbah PLTU dilakukan beberapa pengolahan limbah berdasarkan karakteristik dari setiap sumber limbah yang dihasilkan. Limbah PLTU sudah dapat dimanfaatkan untuk fly ash, buttom ash, dan gypsum. Dalam pengolahan limbah hasil prosduksi, PLTU juga bekerja sama dengan Perusda Pemkab Jepara. PLTU juga telah merencanakan program E-green (perusahaan hijau) yang aman terhadap manusia, lingkungan, efisiensi dalam pemanfaatan SDM, dan mampu berkonstribusi terhadap keanekaragaman hayati.[The research was conducted aimed at knowing the process of water management and waste control at the Steam Power Plant (PLTU) in Tubanan Village, Kembang District, Jepara Regency. This research was conducted using the library method. The PLTU built on the seashore uses sea water as a source of water. The processes carried out in this water treatment include: 1) Distillation, 2) Demineralization, 3) Condensation, and 4) Water Tretment plant. Then in conducting waste control, PLTU is carried out by several waste treatments based on the characteristics of each source of waste produced. The PLTU waste can already be used for fly ash, buttom ash, and gypsum. In processing production waste, the PLTU cooperates with the Regional Government of Jepara Regency. The PLTU has also planned an E-green (green company) program that is safe for humans, the environment, efficiency in utilizing human resources, and able to contribute to biodiversity.]

The present system of recording efficiency parameters under process performance of a steam power plant (SPP) includes specific fuel consumption, auxiliary power consumption, and demineralized water for make-up used during past-specific period, without their integration into a single process performance or efficiency index. For developing integrated efficiency index in real time frame, the use of a process performance digraph (PPD) comprising of P i's as nodes and p ij's as interconnection among the nodes as obtained from the system structure graph (SSG) of SPP has been demonstrated. Each c ij of SSG corresponds to a process, such as air fuel mixing, combustion of mixtuer, generation and expansion of steam and its condensation back into water for recirculation in boiler, etc., taking place in the SPP and corresponds to a P i of PPD. The PPD is then analysed for determining the efficiency of the SPP using matrix method following systems approach. Variable permanent process performance matrix and its variable permanent function (VPF-p) have been derived from the PPD for the analysis. The real-time efficiency index (RTEI) has been introduced which is the ratio of the values of (VPF-p) in realtime (RT) situation (VPF-p)RT to its achievable design value (VPF-p). It reflects the RT rate of consumption of various inputs like demineralized water make-up, auxiliary power and fuel consumption, etc. It provides a more scientific method for ranking the performance of an SPP. The proposed model is capable of analysing in RT the performance of various systems of the SPP, taking into account simultaneously the failure of various equipments in these systems. A step-by-step procedure for calculation of RTEI has also been suggested and illustrated by giving an example.

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.

Steam Power Plants

Most of the electricity being produced throughout the world today is from steam power plants. At the same time, many other competent means of gener-ating electricity have been developed viz. electricity from natural gas, MHD generators, biogas, solar cells, etc. But steam power plants will continue to be competent because of the use of water as the main working fluid which is abundantly available and is also reusable. The condenser remains among one of the key components of a steam power plant. The efficiency of a thermal power plant depends upon the efficiency of the condenser. In this paper, a the-oretical investigation about thermal analysis and design considerations of a steam condenser has been undertaken. A hybrid steam condenser using a higher surface area to diameter ratio of cooling a water tube has been analyzed. The use of a hybrid steam condenser enables higher efficiency of the steam power plant by lowering condenser steam pressure and increasing the vacuum inside the con-denser. The latent/sensible heat of steam is used to preheat the feed water supply to the boiler. A con-ceptual technological design aspect of a super vacu-um hybrid surface steam condenser has been theo-retically analyzed.

Water Pumps

The water pump used to suck and drain seawater to the heat exchanger unit at a Steam Power Plant (PLTU), is damaged. To find out the causal factors of this damaging phenomenon, the fractured shaft is tested which includes visual observation, fractography testing, metallography, hardness testing and chemical composition analysis on a fractured shaft. By knowing the type and cause of damage to the water pump shaft, steps of prevention or prevention can be formulated so that the same damage can be avoided. From the test results, it was found that the average carbon content was lower than the AISI 316 standard. While the average hardness was lower than the standard hardness. The damage that occurs to the CWP water pump shaft is basically caused by fatigue fracture due to excessive workload in the form of dynamic loading
