摘要:
针对供水系统相同工况不同运行方式下能耗差距较大、数据可视化表现形式较为单一等问题，提出采用平行坐标技术对并联机组运行台数、频率、流量与电耗进行可视化分析的方法。通过将理论分析与MATLAB数值拟合相融合，设计了平行坐标人机交互技术，更有效地展现固定流量下机组运行台数、频率和电耗三者之间的关系。对沧州地区三个泵站进行了现场测试和数据分析，其结果验证了结论的有效性和通用性，并进一步修正了机组运行台数、频率和电耗三者之间的关系。在多种机组运行方式满足供水需求的条件下，当不同运行方式间频率差f>4 Hz时，可选择机组台数多的运行方式实现最优运行；而当运行频率差f<4 Hz时，采用机组台数少的运行方式可实现最优运行。
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.
