This study aims to compare and analyze the characteristics of busduct and trunk line equipment for reduction of electric power loss. In order to achieve efficient management of electric power, it is more desirably important to block power loss at the trunk line equipment than to expand production facility. The trunk line equipment should have excellent mechanical and electrical properties, and it is also important to be compatible with a controlling system. As a result, this study proposes the more effective electrical power trunk line model to reduce power loss.
For analyzing power loss of the electrical power trunk line, this study introduced samples that fields of low voltage and high voltage systems, busduct, and trunk line equipment, and it compared electrical properties by simulation, and then it quantifies the result values. This study has carried out two case studies: one for three-phase four-wire 4000[A] system busduct power trunk line and another for cables in IDC low voltage 380[V] system. The case studies have shown that the busduct system provides more power management with less voltage drop and the lower power loss compared to those of the cable, which are mainly due to the length change of the power trunk line with 1.08%(50m), 2.26%(100m), 4.99%(200m), and 12.46%(400m). The average value of the short-circuit current showed the higher as differently as Ip value is 7.12[kA] and Ik" value is 2.71[kA], and also the difference due to changing length is the higher as 19.70[kA] averagely. This study found that occupied area could be reduced as 345,100[㎟] and installing period could be reduced as 2.5 hours, compared to installing period of the cable. Also, the Busduct has a structural advantage that it is possible to connect PMS (a System for Power Management). Therefore, this study could identify that it is a future oriented power trunk line system because it could be possible to make data, as related to operation and power loss of power trunk line equipment, into information.
The achievements of this study could be summarized as follows : ⅰ) This study makes differences of power loss quantified, depending on types of power trunk line and difference values of power loss for high voltage and low voltage systems, and it could compare loss factors.
ⅱ) Also, this study could verify correlation with changing length of the power trunk line and the power loss.
From now on, they are to be expected to change awareness of importance about the power loss in low voltage system, to make vitalize researches in future, and to become a reference material by the results of this study as electrical power system is designed.
