- Abstract:
- Water supply systems under the same working conditions and different operational modes have large gaps in energy consumption, and the data visualization form is relatively single. A method for visualizing the number, frequency, flow rate and energy consumption of parallel units based on parallel coordinate technology was proposed. By combining theoretical analysis with MATLAB numerical fitting, a parallel coordinate human-computer interaction technology was designed for more effectively showing the relationship among the number, frequency and energy consumption of pump units under a fixed flow. The field test and data analysis of three pumping stations in Cangzhou region verified the effectiveness and universality of the conclusions, and the relationship among the number, frequency and energy consumption of the pump units was further modified. When the multiple pump unit operational modes met the water supply demand and the frequency difference f among different operational modes was greater than 4 Hz, the operational mode with multiple pump units could be selected to achieve the optimal operation. When the operating frequency difference f was less than 4 Hz, the optimal operation could be achieved by choosing the operational mode with fewer pump units.
