Design of a 20-kilowatt micro-hydro power system for the electrification of Barangays Rosal and Rivera in Libacao, Aklan
Militar, Jeriel G.
Electrification is vital to the government’s rural development program. However, electrification of remote and isolated barangays via grid extension is currently rendered almost impossible by economic and technical barriers. The alternative to extending the grid to these barangays, as determined by the Department of Energy, is the putting up of a stand-alone community-based power plant. But considering the low income level and the lack of technical know-how of the people in most of these communities, such a plant should be simple enough that it can be operated and maintained by the local people, and should have low operation and maintenance cost such that it can be sustained by the community. This study looked into the feasibility of putting up a micro-hydro power system as an alternative to extending the grid to energize Barangays Rosal and Rivera in Libacao, Aklan, two very remote unenergized barangays which are adjacent to a common waterfall. It was found that installation of a 20-kW micro-hydro power system using locally fabricated turbine, penstock and load controller to serve both barangays was technically feasible; that although the initial installation cost was beyond the paying capacity of the beneficiaries in the two barangays, the project could qualify for a funding from the Department of Energy under the “O Ilaw” Program.

Industrial motor control trainer
Palomo, Rene P.
The study of an Industrial Motor Control Trainer for the students is a contribution to the Electrical Engineering Department of Western Visayas College of Science and Technology. It is a solution to the students’ problem on industry application particularly for the fresh graduates looking for a job. Industries of today are highly advanced when it comes to electric motors. They have come up to many types of motor controls. It is high time that hands on for motor starting and motor controls be made available to the students.
The study of electricity is like a study of air. You don’t learn by merely looking at it, rather, by feeling it or sensing its presence. It is with the recognition of the importance of the power of electricity. In every tertiary level institution, be it of technological, engineering or vocational advocacy, subjects in electricity or electric power are often part of the curriculum.
With the demands of vocational courses, as well as professional electrical courses, the curricula offerings for electrical subjects are being strengthened, either by the provision of competent instructional staff, or the establishment of adequately functional laboratory and skill facilities to cater the needs of the industry and to achieve the instructional goals of the institution.
To answer this problem, the proponent of this study aims to design and construct an industrial motor control trainer as an instructional device in teaching motor controls in the electrical engineering program.
The findings of the study show that:
1. The trainer could perform more than twenty laboratory exercises efficiently.
2. The trainer can be use in applying the principles, theories and functions of industrial motor control trainer.
3. The trainer can be use as a demonstration unit to the students by showing the different electrical circuits that the trainer could perform.
4. The trainer can be use to discover, create or formulate new electrical circuit in the motor control.
5. The trainer can perform as a fault simulator to develop students’ skills and knowledge in electrical circuits or trouble shooting.
6. The device is economical in terms of construction and maintenance.
7. The trainer is made of light material to facilitate transferring and mobility.
8. Necessary precautions have been observed to insure maximum effectiveness and safety.
Based on the findings of the study, the conclusion is given:
The industrial Motor Control Trainer can be designed and constructed.
Based on the conclusions drawn, it is recommended that:
1. The result of this study be disseminated to the field in order that administration and electrical engineering instructors will be informed of its use.
2. The Industrial Motor Control Trainer should be used as an instructional device in the teaching of Electric Motor Control.
3. The preparation of modules and instructional manuals be encouraged among electrical engineering instructors to improve classroom instruction.
4. Electrical Engineering instructors be encouraged to construct and improve the model using electronically controlled system for advancement of instructional process in electrical engineering.
5. A rack of electric motor be provided to further improve the gadget.
6. Financial support from government and non-government agency for the mass production of the trainer be extended to those who desire to undertake the job.
7. A replication of this study be made using another sample in a different setting.

Proposed optical backbone for Central Philippine University (CPU) local area network
Perucho, Arvin T.
This Special Problem Report dealt with the proposed backbone design and fiber optic installation for the local area network (LAN) of Central Philippine University. Progressing from the current use of copper wire to the fiber optic cable will enhance the quality of service of the institution’s information network by increasing the rate of transmission of data, decreasing the effects of interference, decreasing attenuation or transmission loss, and increasing the capacity of the network channel.

Proposed rehabilitation of Silliman University campus distribution line system
Ygnalaga, Edgar S. Jr
The purpose of this paper is to propose a rehabilitation plan and design of the distribution line system of Silliman University Campus, thus determine the appropriate ratings of transformers, sizes of conductors, types of pole and pole wire arrangement that would enhance the distribution line system to sustain the needed power of its load today and in the future.
Since the load already exists, actual determination of the individual loads and the type of service they are served, three (3) phases or single (1) phase, were done. Buildings and structures equipped with watt-hour meters, and load data gathered are classified as average loads, and without watt-hour meters, and load gathered are classified as connected loads. Using the two load data gathered, average and connected loads, the maximum demand of the buildings and structures were calculated using load factors and demand factors in Table 1, Appendix C and were tabulated in Table 4, Appendix C. Buildings and structures were grouped in the preference of their locations based on the actual campus plan. The maximum demand will be used to determine the transformer size and conductor sizes, with considerations of diversity factors among consumers in Table 2, Appendix C, 100 % load growth and 10 % distribution loss that would supply the particular group of loads.
After the loads have been grouped in Appendix B, the number of feeders and the number of group loads that will be supplied by the feeder transformer were determined using the maximum demands of the grouped loads. Determination of feeder transformer size and conductor sizes were done with consideration of diversity factors among transformers, load growth, and distribution loss. Standard conductor sizes were determined in Table 3, Appendix C. The last transformer size to be determined was the main transformer size. This main transformer is the interconnection of the local electric cooperative and Silliman University. From the summed maximum demands of the feeders, the main transformer size was determined, with consideration of diversity factors among feeders, load growth, and distribution loss.
The one line diagram of the proposed distribution line rehabilitation is depicted in Figure 2, Appendix D. Figure 2 also includes transformer kVA rating, primary and secondary voltage ratings, and connections as well as specifications of the existing generator sets.
A plan is provided to show the route of the line, placement of poles, primary and secondary, and transformer bank stations.
