Abstract：Based on the operating characteristics of the power-distributed system,the Pipe Flow Expert professional simulation software is used to construct a refined model,and the comprehensive performance differences between the power-distributed system and the traditional power-centralized system are systematically compared and studied from the aspects of energy consumption and hydraulic characteristics.The results show that the power-distributed system reduces the total energy consumption of the water pumps by 40.8%by replacing the balance valve with distributed water pumps in each branch,and the energy-saving effect is obvious.However,due to the enhanced coupling degree between branches,when some branches are shut down,the flow offset coefficient of the remaining branches reaches 1.15,which is higher than 1.12 of the traditional system.The system stability and anti-interference ability are relatively weak.
