Özet
Transmission line efficiency is critical to support the overall power grid and the growing energy demand. This study investigates the optimal transmission line voltage selection to minimize resistive losses while balancing associated economic and physical constraints. To evaluate these trade-offs quantitatively, Microsoft Excel Solver was utilized to develop a model for analyzing power transmission across a variety of transmission powers (10-400MW) and line lengths (60-160km). Constraints were established for minimum conductor sizes allowed at different voltages. The goal of the model is to determine the voltage level that results in the lowest conductor material costs, structural costs, and long-term cost of resistive losses. Additionally, the model selects the conductor type (from available conductors) most suited for the variables at hand. The results show that while resistive losses are reduced as voltage increases, the most economical solution is often one that balances these costs for the transmission line's distance and load. At lower to moderate power loads (10MW, 50MW, and 150MW), the model selected 230kV as the optimal voltage to minimize conductor material costs, structure costs, and resistive losses. At the highest load evaluated (400MW), the model selected 500kV as the optimal voltage to minimize overall costs. This data provides crucial guidance for transmission planning, as it demonstrates that optimization cannot rely solely on electrical efficiency and must also account for material costs and system constraints.
