I、Research Project Abstract
Extra High Voltage Project─Longzaki Extra High Voltage Substation
Electricity is a symbol of modern human civilization. If there were no electricity, modern human civilization would be dying out! In order to provide sufficient and stable power, with lots of effort, a group of anonymous heroes have to devote temselves to providing enough electricity for everyone in a 24-hour nonstop relay. This time we are going to ex-plore one of the important links ─ EHV substation. About 2 km near the school, there is a " Longzaki Extra High Voltage Substation ", which is one of the largest EHV substations in Taiwan and one of the most important substations. It receivess the extra high voltage cur-rent from the third nuclear power plant in Taiwan and Xingda thermal power plant. Throughstep-down converter, this substation transmit electricity to Taiwan around. Without this EHV substation working for 24 hours everyday , one third of Taiwan may be covered by darkness. Today with the students from Wen He Experimental Elemtary School, we hope that we can take a closer look into Longzaki Extra High Voltage Substation.
Longzaki EHV Substation is the nearest substation to Wenhe Experimental Primary School and one of the most important substations in Taiwan. It was once the largest substation in Southeast Asia. Taiwan's third nuclear power plant and Xingda thermal power plant, the power generated by the two power plants is sent directly to the EHV substation buck and delivery tasks, for such an important neighbor, we are curious about it , But also because of the presence of Longzaki substation, so that the vicinity of schools covered with high-voltage electrical towers and high-voltage wires, can be described as "earth network", often heard of high voltage will affect human health, is it true? To find out, we selected "Longzhuang UHV substation" this year as our theme, hoping to solve some of my doubts.
- This project aims to encourage students to understand what EHV substation is. Students also learn to find the way to observe the configuration of UHV substations. Before the field trips and interviews, students have to surf on the Internet first to read and find out relevant information. By doing so, students can go into the situation quickly, and learn more while they are do research at the EHV substation.
- The benefits of teamwork bring higher quality, and increase efficiency and mutual sup-ports. This CyberFair project allows students to work both individually and as a team to explore new knowledge on the Internet. The students also learn how to classify, analyze and organize different ideas and opinions that they have come out of. The importance of teamwork to achieve the goal is cherished by every student who participates in this pro-ject.
- Teamwork in this project Teamwork in this project allows students to maximize overall productivity and communi-cation skills. We believe that the teamwork and leadership skills which students have ac-quired in this project would benefit their future study while they are trying to achieve higher education goals.
IV、Problems Encountered and Overcome
- Although it is only 10 minutes driving from our school to Longzaki Extra High Voltage Substation, due to few public transport service, students can only do the observation with the help of school teachers who have cars and time to pick up.
- EHV substation, after all, is not an amusement park and a large part of the region is dangerous. Therefore, teachers can not let students observe in the substation at will without any adults’ company. Also, some eqipments are too professional for students to understand the theories behind them. Therefore, we can only try our best to carry out thematic research on the humanities of the substation, hoping to really have some growth and gain precious experience.
- The internet access is not pevalent in some area of Budai Li. Hence, for those students who have no Internet at home, they could only spend their spare time as much as possible doing the project at school..
Many people in Taiwan are scared of living closed to substations, because of some negative medical reports on electromagnetic waves in the past. Therefore, few people wanted to live nearby substations, let alone "EHV substations!" However, we are curious that if electro-magnetic waves had such a negative impact on the human body, every employee who works there would be surrounded by a high level of danger all year round, wouldn’t they? In ad-dition to unveiling the mystery of "EHV Substation", our team also hope that by interview-ing the staff inside to understand their health conditions, we can make a circumspective re-port on how the electromagnetic waves affects humanbody. Perhaps there is no such evi-dence that the electromagnetic waves do seroius harm to our health and without the stereo-type of EHV, people would more willing to accept the "special neighbor."
The results on the web page we have made will be completely open to the public. Anyone who is interested in the topic of "EHV substation" can freely browse the web. We hope to help the community and students have better understanding of the " Longzaki Extra High Voltage Substation."
Before exploring " Longzaki Extra High Voltage Substation", there is a stereotype that it was nothing more than a voltage-changing place. However, after it was explored, we realized that it was not as horrible as it imagined. Instead, we feel so proud that such an important substation is near my home. Thanks to the devotion of those people working in the substa-tion, without them, one third of Taiwan's land will plunge into darkness and many things will shut down. We admire their effort from the bottom of our hearts, because those staffs are responsible for the operation of the most important substation in Taiwan. They have to face the ice-cold machines for a long time with all their minds in such dangerous surround-ings. In the end, we are no longer afraid of substations due to our ignorance.
