Presented to The Faculty of the Mechanical Engineering Department In Partial Fulfilment of the Requirements for ME 518 – Power Plant Engineering Submitted by: Kevin Jhon Cuario Tolentino Rosil John P. Bunaos Warren Saranillo Ryan Ybanes Submitted to: Engr. Dominador J. Go, PME July 2020
Chapter 2 Plant Location and Condition I. Plant Location The proposed gas turbine power plant will be located at near alangilan, Sagay, camiguin Island with map coordinates of 9°6'N 124°43’E. The power plant site has 6,300 m^2 area and its main consumers are the residential area near to it.
Figure 1 .1 proposed gas turbine power plant site II. Site Condition The proposed plant is located at Sagay, Camiguin Island. Since climate at camiguin doesn’t change dramatically all throughout the year, then it is safe to use its average climate conditions. Climate Tropical Air Temperature 32 °C Relative Humidity 73% Wind 15km/hr Atmospheric Pressure 101.325 Kpa Elevation 29.2m( above mean sea level ) Soil Type Clay, compact

Chapter 5 Design Standards I. Plant Standards In the construction of the gas turbine power plant, it must follow certain standards. This standard must be met during and after the plant construction and operation. This standard has been proven and tested by a reliable institution that can be trusted. Selected standard has been listed below: Management o ISO 50001 / ISO 9001 / ISO 14001 – Energy Quality and Environmental Management Systems Package o ANSI/ASQC E1-1996 – Quality Program Guidelines for Project Phase of Nonnuclear Power Generation Facilities Equipment o IEEE 1250-2011 – IEEE Guide for Identifying and Improving Voltage Quality in Power System o DIN EN 45510-2-4:2011 – Guide for procurement of power station equipment – Part 2-4: Electrical equipment; High power static converters; English version of DIN EN 45510-2-4 (FOREIGN STANDARD) o NECA/EGSA 404-2014 – Standard for Installing Generator Sets o DIN EN 45510 -2-2:1999 – Guide for procurement of power station equipment – Part 2-2: Electrical equipment – Uninterruptible power supplies ( FOREIGN STANDARD )
o ASTM D6224-16 – Standard Practice for In-Service Monitoring of Lubricating Oil for Auxiliary Power Plant Equipment Fans o AMCA 801-01 (R2008) – Industrial Process/Power Generation Fans: Specification Guideline Gas o AGA F22001 – Impacts of Power Generation Gas Demand on Natural Gas Local Distribution Companies o AGA F69610 – Existing and Future Electric Generation: Implications for Natural Gas o ISO 11365:2017 – Petroleum and related products – Requirements and guidance for the maintenance of triaryl phosphate ester turbine control fluids Turbine o ASTM D4378-13 – Standard Practice for In-Service Monitoring of Mineral Turbine Oils for Steam, Gas, and Combined Cycle Turbines Industrial o ISO/ASME 14414:2015 – Pump System energy assessment o IEEE Std 3007.1-2010 – IEEE Recommended Practice for the Operation and Management of Industrial and Commercial Power Systems o AMCA 850-02 (R2011) – Industrial Process/Power Generation Heavy Duty Dampers for Isolation and Control o SAE J 1939-75-2015 (SAE J1939-75-2015) – Application Layer – Generator Sets and Industrial
Sustainability. Depicts the durability of the product basically, its ability to withstand the environment in which it is located and the length of its operating lifespan. This also refers to the ability of the product to still work under heavy conditions. Expected lifespan. The expected lifespan of the product is the ability of the product to maintain its service under a given time frame Performance under heavy usage. Refers to how the product function under heavy usage under prolonged periods with steady performance. Manufacturability. Refers to the ease of assembly, its availability for mass production and will contribute to the high return of investment to its manufacturers. Marketable. The marketability of the product is its effectiveness in penetrating target markets and can sustain a steady foundation on its classification. Social. Relating to community or any organization that can benefit to the design Manufacturability. In this factors like availability of materials, easy to build, marketable, and lesser production cost are the main consideration of the design. While for the criterion of easy to build, design is considered to be the manageable one because it will use a much lighter turbine. Then for the criterion of being marketable, both designs are considered effective in penetrating the target market. Sustainability. In this constraint factors like estimated life span, performance under heavy usage and maintenance are the main consideration of the design. while for the maintenance design is expected to gain a much lesser cost and lastly for the performance under heavy usage. Economy. In this constraint, the only factor that is considered is the affordability of the designs. For this factor design is considered to be the affordable because the rate of each turbine is much smaller which means lesser cost.
Chapter 7 Cost Analysis The other objectives of this study is to present a cost analysis. Focusing of cost analysis is the payback period which will determine the number of years to wait in order to start gaining profit and also will indicate the economic span of the machine. For obtaining the payback period, the proponents provided the needed data such as the operating hours of the machine per day and the capacity of the machine per day. The proponents solved for the repair and maintenance that includes the labor cost, annual benefits, and annual investments. Solving theses data simultaneously would eventually lead to the solving of the payback period and the cost-benefit. For the solution of these data, the researchers used the formulas found in the reviewer Engineering Mathematics Volume 2 – Second Edition by Diego Inocencio T. Gillesania.
