چکیده :

Balance of plant (BOP) is a term that refers to all the supporting components and auxiliary systems of a combined cycle power plant (CCPP) needed to deliver the energy, other than the generating unit itself. The cable sizing of this part has particular importance in the CCPP. Different Site conditions and cable installations directly affect the current carrying capacity and Subsequent cable sizing. In this article, different modes are investigated, and the results are analyzed. It is shown that when there are no clearances between adjacent cables on a ladder, a more pessimistic condition is observed than the case where the cables are far apart. Cable sizing methods are at variance across international standards. For example, International Electrotechnical Commission (IEC), National Electrical Code (NEC), and British Standard (BS). In this research and Comparison between different modes, IEC 60364-5-52 standard is used. Another influential factor in determining the size of the cable is to pay attention to the minimum short circuit current at the end of the cable. This parameter is discussed in two IEC and ABB standards, which differ due to specific coefficients. In the following, it is shown that there may be no difference between these two standards.
