<p><em>The Pacitan Power Plant is one of the power plants in East Java that has a capacity of 2 x 315 MW which was built by the government in the Fast Track Program 1. The Instrument Air Compressor (IAC) is one of the auxiliary equipment at the Pacitan Power Plant that provides air supply to the factory's advanced pneumatic system. However, this equipment cannot be monitored by the Central Control Room (CCR) operator to the maximum. The parameters that can be controlled are very limited. This is due to the limited number of available Field Bus Module (FBM) terminals. The problem formulation is how to create a communication module to display the parameters of the Air Compressor System Instrument to display the HMI CCR operator in real time. The purpose of designing tool is to create a safe and reliable communication module to display all the parameters of the existing Air Compressors to be displayed in the CCR’s computer display. The method used is the control and transmission parameters that are transmitted from the field to the Central Control Room using serial communication RS485 Modbus Protocol. </em><em></em></p>

Radiological Consequence

The major threat that nuclear power plants (NPPs) pose to the safety of the public comes from the large amount radioactive material released during design-basis accidents (DBAs). Additionally, many aspects of Control Room Habitability, Environmental Reports, Facility Siting and Operation derive from the design analyses that incorporated the earlier accident source term and radiological consequence of NPPs. Depending on current applications, majority of Chinese NPPs adopt the method of TID-14844, which uses the whole body and thyroid dose criteria. However, alternative Source Term (AST) are commonly used in AP1000 and some LWRs (such as Beaver Valley Power Station, Units No. 1 and No. 2, Calvert Cliffs Nuclear Power Plant, Unit Nos. 1 And 2, Kewaunee Power Station and so on), so it is attempted to adopt AST in radiological consequence analysis of other nuclear power plants. By introducing and implementing the method of AST defined in RG 1.183 and using integral safety analysis code, a pressurized water reactor (PWR) of 900 MW nuclear power plant analysis model is constructed and the radiological consequence induced by Main Steam Line Break (MSLB) accident is evaluated. For DBA MSLB, the fractions of core inventory are assumed to be in the gap for various radionuclides and then the release from the fuel gap is assumed to occur instantaneously with the onset of assumed damage. According to the assumptions for evaluating the radiological consequences of PWR MSLB, dose calculation methodology is performed with total effective dose equivalent (TEDE) which is the criteria of dose evaluation. Compared with dose criteria of RG 1.183, the dose of control room, exclusion area boundary and outer boundary of low population zone are acceptable.

Dry Cooling

Large natural gas fired combined cycle electric power plants, while being an increasingly efficient and cost effective technology, are traditionally large consumers of water resources, while also discharging cooling tower blowdown at a similar rate. Water use is mostly attributed to the heat rejection needs of the gas turbine generator, the steam turbine generator, and the steam cycle condenser. Cooling with air, i.e. dry cooling, instead of water can virtually eliminate the environmental impact associated with water usage. Commissioned in the fall of 2010 with this in mind, the Halton Hills Generating Station located in the Greater Toronto West Area, Ontario, Canada, is a nominally-rated 700 Megawatt combined cycle electric generating station that is 100 percent cooled using various air-cooled heat exchangers. The resulting water consumption and wastewater discharge of this power plant is significantly less than comparably sized electric generating plants that derive cooling from wet methods (i.e, evaporative cooling towers). To incorporate dry cooling into such a power plant, it is necessary to consider several factors that play important roles both during plant design as well as construction and commissioning of the plant equipment, including the dry cooling systems. From the beginning a power plant general arrangement and space must account for dry cooling’s increase plot area requirements; constraints therein may render air cooling an impossible solution. Second, air cooling dictates specific parameters of major and auxiliary equipment operation that must be understood and coordinated upon purchase of such equipment. Until recently traditional wet cooling has driven standard designs, which now, in light of dry cooling’s increase in use, must be re-evaluated in full prior to purchase. Lastly, the construction and commissioning of air-cooling plant equipment is a significant effort which demands good planning and execution.

ABSTRACTThe role of central control room (CCR) operator in Steam Power Plant (PLTU) or Gas and Steam Power Plant (PLTGU) of a work environment has high noise intensity with range (62.2– 99.8 dBA). Noise resulting from the process of production of electrical energy by machinery such as power generation unit boiler/HRSG, turbine, generator, condenser and other supporting equipment can cause Noise Induced Hearing Loss (NIHL). Study with cross-sectional design aims to analyze the difference in Noise Induced Hearing Loss between shift operator CCR PLTU and PLTGU PT PJB UP Gresik. Research on samples taken with the technique of simple random sampling with the majority of respondents were ≥ 40 years old, have a working periode ≥ 4 years, have a work area with a level of intensity noise > 85 dBA, long exposure noise ≤ 1 hour and good level of compliance of the use of ear protection in both of units. There was a difference of NIHL shift operator CCR PLTU and PLTGU. The number ofoperator who have experienced hearing loss due to noise on the shift operator CCR PLTU greater than PLTGU. Shift operator CCR PLTU and PLTGU are advised to obey and comply with safe working hours in areas with particular noise intensity has been set and the use of ear protection with right, also have to perform regular an audiometry exam tests so that the function of hearing of shift operator CCR could in monitor continuously.Keywords: central control room operator, power plant, noise induced hearing loss

Unfired combined-cycle power plants of Siemens/KWU design each comprise five different package-engineered functional areas of mechanical and associated electrical equipment which are matched to different fuels, site conditions and operating requirements in order to achieve optimum power generation with each application. A modular programmable microprocessor-based automation station allocated to each functional area sequentially controls and protects all the equipment therein. By means of a redundant bus system all the functionally distributed automation stations are connected to one another and to a central control room where VDU screens provide operators with an in-depth insight into the running performance status of the entire combined-cycle block at all times. Function keyboards and back-up conventional hardwired controls permit operators to intervene in the automatic operation of the station whenever desired.

The need for electrical energy in Indonesia continues to increase every year. In line with the increase in the electrification ratio to 100% in 2050, the demand for electrical energy is projected to reach 7 times, namely 1,611 TWh. To meet electricity needs, the government has created a 35 GW program, but one of the largest contributors to power generation fuel is coal with a share of 58% or around 50 GW which is estimated to be exhausted within the next 68 years. For this reason, innovations are needed in terms of fulfilling electrical energy by utilizing renewable energy potential, one of which is hydro energy, which is 45,379 MW from a total resource of 75,091 MW. Therefore, from this potential, innovations related to renewable energy have been created, namely the Hybrid Portable Underwater Turbine Hydro and Solar Energy hybrid power plant. This power plant uses an undersea current as a propulsion which is hybridized with solar power to increase the production of electrical energy. This power plant has the advantage that there is an Underwater turbine design that is resistant to underwater flow and a water flow direction to increase the work efficiency of the underwater turbine. From the test results, the portable Underwater turbine hydro produces 950 W in a day. Solar panels produce 65.6 Watts a day. The total hybrid that can be produced is 1.02 kW a day. In its implementation it can supply loads of up to 900 (VA) such as lamps, fans, TV, etc. This hybrid power plant can be a solution to help meet electricity needs in the area around Dusun Dongol, Sidoarjo through alternative electrical energy innovations.

The linear programming (LP) model has been used to identify a cost-effective strategy for reducing CO2 emissions in power plants considering coal washing, pollutant removal, and carbon capture processes, thus CO2 emissions in different production processes can be obtained. The direct emissions (combustion emissions and desulfurization emissions) and indirect emissions (pollutant removal, coal washing, and carbon capture) of CO2 were all considered in the LP model. Three planning periods were set with different CO2 emission control desirability to simulate CO2 emissions of the different reduction requirements. The results can reflect the CO2 emissions across the whole production process of a coal-fired power plant overall. The simulation results showed that for a coal-fired power plant containing two 1000 MW ultra super-critical sets, when the desirability was 0.9, the CO2 total emissions were 2.15, 1.84, and 1.59 million tons for the three planning periods. The research results suggest that the methodology of LP combined with fuzzy desirability function is applicable to represent the whole production process of industry sectors such as coal-fired power plants. The government policy makers could predict CO2 emissions by this method and use the results as a reference to conduct effective industrial and energy structure adjustment.

The Government of Indonesia is committed to realize a policy of 35,000 Megawatt (MW) of an additional supply of electricity within 5 years (2014-2019). The projection of this capacity is largely supported by fossil fuel power plants and a small portion of renewable energy. One of the renewable energy which currently has great potential in Indonesia is the geothermal. Therefore, improving the capacity of geothermal is needed to support the policy. The Kamojang is one of the largest geothermal power plant in Indonesia with an installed capacity of 235 MW from 5 generating units. The purposes of this research is to calculate the energy and exergy analysis at Kamojang geothermal power plant. To improve the capacity, exergy analysis can be used by employing the thermodynamic method. In this research, unit 2 of Kamojang's plant is employed. The analysis was examined by using the Engineering Equation Solver (EES) code. The results show the first law of efficiency was calculated at 19.03% and the second law of efficiency at 40.31%.

This paper investigates how the government can develop subsidies or tax policies to incent power plants to effectively carry out carbon capture to reduce carbon emissions. According to the government’s incentive model for carbon capture power plants, the regulation mechanism is developed when government controls carbon emission. When regional or national carbon emission quota is tense, significant effect can be obtained when regulators make regulations to take off low efficiency power plants. In addition, it is verified that the regulators should not blindly pursue a reduction in carbon emissions regardless of the cost. Therefore, regulators need to pay more attention to control the costs of carbon capture equipment and technology. Finally, by parametric and numerical analyses, the conditions of the power plant to maximize corporate surplus are further studied.

The compressed air supply device on the ship is auxiliary equipment used for starting the engine. The purpose of this study is to analyze the performance of the air compressor as a generator source in the Engine Hall laboratory. This study seeks to determine the performance of the compressor sistem as a generator drive in the Engine Hall Laboratory and the efficiency of the compressor sistem. The methodology used in this research is a quantitative method by calculating the performance of the compressor sistem as a generator, including compressors and wind bottles. The conclusion of this study is that the smaller the pressure exerted when compressing the air into the wind bottle, the smaller the mass of air that enters the wind bottle, likewise the greater the pressure exerted during compression, the greater the mass that enters the wind bottle (202, 65 kPa with an air mass of 1.0393 kg and 2431.8 kPa with an air mass of 12.162 kg). The smaller the pressure exerted when compressing the air to the wind bottle, the greater the mass flow rate of air in the tube (202.65 kPa with an air mass flow rate of 0.0297 kg/sec and 2431.8 kPa with an air mass flow rate of 0.0115 kg / sec). The greater the sistem output power, the greater the efficiency of the compressor sistem and the smaller the sistem output power, the smaller the efficiency of the compressor sistem (1000 Watt with an efficiency of 26.311% and 218 Watt with an efficiency of 5.742%).
