| Summary: | ecently, many people fear about the radiation exposure from the transmission line in Malaysia. There are very few people who can differentiate between ionizing and non-ionizing radiation. "Radiation" from the high-voltage transmission line consists of a magnetic field and electric field. In this project, the magnetic field from transmission line was calculated using MATLAB programming. The calculations are base above one meter from the ground and across the transmission line. The new positions of conductors were determined using Particle Swarm Optimization technique to get the minimum value of magnetic field. The technique is represents the movement of organisms such as bird flock or fish school. Particle swarm consists of 'n' particles and the position of each particle stand for the potential solution in 'D' dimensional space. The particles change its condition according to the following principles; to keep its inertia, to change the condition according to its most optimist position, and to change the condition according to the swarm’s most optimist position. The magnetic field was calculated with several design of transmission line and then the new positions of conductors with lowest magnetic field were determined. The results have been compared with Table 5.1 in this report and found that it meets the magnetic field value at a voltage of 400kV. As the magnetic field produced became lower, the magnetic field exposure to the public nearby the transmission line also will be low. Hopefully, this will be useful for the designers or engineers to design the lower exposure of magnetic field from the transmission lines hence will be able to meet the safety limit exposure to the public. |
