Report on Educational Tour February 26 – March 1, 2014 Subic Power Plant SBITC Subic Airport Container San Roque Power Plant Pag Asa-Baguio EXECUTIVE SUMMARY I.

Introduction

By conducting the educational tour, it can help us students to be more knowledgeable and familiar with the things that are related to their course. Educational tour gives us ideas likewise opportunity to visit power generating plants to be able to experience what it’s like to be there. Moreover, it is important to every student since it is a part of our learning process and to acquire more knowledge through the actual exposure to the different machines and equipment and system operations of the plant. For this reason, the De La Salle University-Dasmarinas, College of Engineering provides high standard of education to the students with the incorporation of field trip/ seminars in the curriculum. II.

Objectives of the Tour

The specific objectives of the tour are:

1.

Real-world experience - Students practice their skills and critical thinking abilities

outside of the controlled class setting. Being about able to ask experts about their particular area of study on the spot requires thinking. He is able to learn real-world lessons. 2.

Reinforcement - The tour can reinforce or what a teacher has been

instructing in class about a subject and help students understand a topic better. 3.

Engagement- Teachers turn tours into mobile classrooms, and engage students to

collect data then asg a project based on what they learned during the duration of the tour. 4.

Socialization- Taking students into a new environment give us the experience of

traveling in a group and teach us to socialize and to be respectful of the locations they visit.

5.

New Insights- The tour can give new insights of the things outside the school which

can raise encouragements. 6.

Bonding -They may be able to connect on more of a personal level without the

structure of the normal school days. Students may be able to spend much of the trip day in small groups, observing, chatting and learning about each other, and it will form a new bond among the students. 7.

Fun - No matter how much the students learn during a tour, their favorite memories

may be based on their enjoyment of the day. Students will have fun with their friends and they also may return to the classroom with a renewed focus on their schoolwork

III.

Significance of the Tour

The tour provided valuable educational opportunities away from the classroom, without using textbooks and other used in normal school setting. Students on educational tours can often learn while having fun in a more informal environment. Part of how students benefit from educational tours is by gaining new perspective on the world. This is especially true for more extensive educational tours or trips where students travel farther away from home. By coming into direct with a different environment or even a new culture, students can better understand their place in the community and develop openness to differences in others.

IV.

The Educational Tour

Prior to the actual visiting on companies and power plants, we then headed to different destinations in Northern Luzon where we were assisted by personnel, which provided us insights and chances for our questions to be entertained. Relevant information was acquired and actual exposure to the power plant environment and control systems was experienced.

Subic Power Plant The Subic power plant is an oil fired power plant having an installed capacity of 110 MVA composed of 8 combustion-type generators which contribute 14.5 MVA each. The personnel said that one of the generators is not which yielded to lower capacity of the plant.

Each of the combustion generators is composed of 18 valves which are periodically maintained and inspected. The generators generates 13.8 kV which is then to be step up to 230 kV by two 55 MVA transformers to be fed on the transmission line grid. The personnel said that one of the most challenging part of their work there as the operations engineer was when the grid demands supply from them, when the supply in spot market is insufficient, he said that there were times that they needed to run the plant continuously in order to meet the demand from the grid.

Subic Airport Container

Subic Bay International Airport serves as a secondary airport and a main diversion airport of the Ninoy Aquino International Airport. It is also the airport serving the immediate area

of

the Subic

Bay

Freeport

Zone and

the

general

area

of Olongapo

City in

the Philippines. This airport used to be the Naval Air Station Cubi Point of the United States Navy. Its airport terminal has 2 gates. The speaker there discussed about the flow of engers on the airport. He said that coordination upon the istration and the enger is vital upon maintaining effective and organized flow.

Subic Bay International Terminal

The tour then headed to Subic Bay International Terminal. The personnel there then discussed about the basic operations in the container terminal, he discussed about the

safety precautions, capability of the machines and other relevant information about the container terminal operations. He also mentioned that the new container terminal is owned and operated by the Subic Bay International Terminal Corp. SBITC, is an ICTSI Group Company, that has been serving the growing economy of the northern regions of the Philippines through world class container handling services at the Subic Bay Freeport at the Naval Supply Depot (NSD). SBMA began constructing a dedicated container terminal, the New Container Terminal Compound (NCT-1), as part of its Port Development Master Plan. SBITC was awarded the management and operation of the New Container Terminal-1 (NCT1). In 2008, commercial operations commenced and container handling operations at the NSD Terminal were transferred to the NCT-1 located at the Freeport´s Cubi Point. As the NCT-1 terminal operator, SBITC is committed to further develop facilities and provide services at par with the world´s leading container terminals.

San Roque Power Plant

The tour also headed to San Roque Dam to visti the power station. The personnel in the site then discussed about the operations, maintenance and other relevant information regarding the plant. He discussed that San Roque Power Plant has an installed rated capacity of 345 megawatts (MW). It operates primarily as a peaking plant during periods each day when the electrical output of base and inter-mediate load power plants cannot fulfill consumer demand. The personnel there then also provided handouts which includes technical information about the dam.

As an electrical engineering student, this provided good insights regarding the capability of the power plant. Moreover, the tour visits the actual site of the power plant where the generators and other vital power plant equipment and controls systems were located.

PAGASA Synoptic Station -Baguio

The tour also visits the PAGASA Synoptic Station at Baguio. The synoptic station was established since 1951 and as I observed they use old equipment which are mostly analog type for their measurements and forecasts. As the personnel discussed, the equipment are still in good condition although there are some drawbacks upon using analog equipment, they are just maximizing of what are available to them. He also discussed about the weather elements and other information regarding weather forecasting he then discussed about different weather equipment and its functions.

I gained understanding to a lot of things upon the tour, some are new information for me and some are not. Mostly, what I have learned are not about the things the company are being particular of, actually, it’s about how engineering improves and serve people. By making the tour and having those companies visited actually planted the reality of life to us. It made us realized what to do, how to do things, why we should do, when to do thing accordingly, most of our questions were answered. The exposure and engagement we had will greatly affect our attitude towards the movement on the industry today.

Report on Seminars S.Y. 2013-2014 2nd Semester Wireless Electric Power Transmission Electrical Grounding System Solar Energy

Wireless Electric Power Transmission Speaker: Engr. Isabelo B. Hugo PEE, MBA Electrical Engineering Department De La Salle University-Dasmarinas February 21, 2014

The speaker started upon discussion basic electrical engineering principles that are related upon wireless power transfer, then the discussion leads into the topic which is wireless power transmission. Relevant information was discussed by the speaker; some of it are basic which still retains on my mind. The speaker pointed out that wireless charging is a form of wireless power transmission. Wireless charging, also known as inductive charging, is based on a few simple principles. The technology requires two coils: a transmitter and a receiver. An alternating current is ed through the transmitter coil, generating a magnetic field. This in turn induces a voltage in the receiver coil; this can be used to power a mobile device or charge a battery. Wireless electricity is quite literally the transmission of electrical energy without wires. People often compare the wireless transmission of electrical energy as being similar to the wireless transmission of information, for example radio, cell phones,

or wi-fi internet.

The

major

difference

is

that

with

radio

or

microwave

transmissions, the technology focuses on recovering just the information, and not all the energy that you originally transmitted. The speaker also mentioned about WiTricity. WiTricity is based on strong coupling between electromagnetic resonant objects to transfer energy wirelessly between them. This differs from other methods like simple induction, microwaves, or air ionization. The system consists of transmitters and receivers that contain magnetic loop antennas critically tuned to the same frequency. The seminar give insights about the capability and potential upon innovating in the field of wireless power transmission, this inspired us as future electrical engineer to be more creative and innovative in our field of study.

Electrical Grounding System Lyceum of the Philippines-Cavite January 16, 2014

The seminar was conducted as part of the assembly of Integrated Institute of Electrical Engineer, Southern Luzon Chapter. The seminar aimsedto make grounding and bonding of electrical systems a less daunting process. A balance of theory and practice will provide a firm foundation of knowledge for your next design or construction project. The course material will prepare you to correct problems in your electrical system and improve safety, efficiency, and power quality. Additionally, case studies will be used to discuss grounding and bonding applications in a variety of areas, reinforcing fundamental principles. The main objective of the seminar is to familiarize participants with the fundamentals, applications, and necessity of electrical grounding and bonding techniques, thereby improving personnel safety and operations efficiency. The spekear discussed about the electrical grounding system, how should it be done according to the Philippine Electrical Code, and its importance. Grounding and shielding electrical systems are of key importance to electrical engineers. Understanding the basic operations between grounded and ungrounded electrical systems is necessary for matching the appropriate grounding topology to the desired electrical system performance. Selecting the proper grounding topology for an electrical distribution system is important to ensure facility occupant safety and health as well as reliable and safe electrical equipment operation. After attending the seminar I was able to identify and prevent safety hazards to personnel who come in with electrical systems, realized how to prevent equipment failures and malfunctions by employing proper grounding techniques, interpret codes and standards related to grounding, how to ensure proper operation of communications, computer, and control systems, andapply lightning protection methods to my future projects.

Solar Energy Lyceum of the Philippines-Cavite January 16, 2014

The seminar was also conducted as part of the assembly of Integrated Institute of Electrical Engineer, Southern Luzon Chapter. The speaker discussed about the basic compositions of photovoltaic cells, how is it array into solar s, proper positioning of s to maximize the harness of solar energy and maintenance. When deciding on a location for solar s, make sure no shadows will fall on the solar array during peak sunlight hours (say, 9am to 4pm). Not only will shading of the solar s significantly reduce their output, but also could cause damage. Some solar manufacturers s that can withstand shading but they use internal diodes which in themselves reduce the power somewhat. I recommend simply choosing a good location to start with, even if it means cutting down a few trees or otherwise removing obstacles. As previously discussed, you want to mount solar s in a sunny and nonshaded location to get maximum sun. But, heat build-up is also a problem. Because the efficiency of solar s decreases as temperature increases, the solar mounting system should allow for spacing around the individual solar s for air circulation. The idea is to allow air cooling in the hot sun to reduce the temperature of the solar s. Another consideration is wind loading. By allowing air to flow around the solar s, not only will they remain cooler, but also the wind resistance of the entire array is less.
