摘  要：基于供水系统SCADA数据构建水厂变流变压曲线模型，曲线任意点的出厂压力随出厂流量的变化而调节并推断末端压力恒定，桂城水厂应用高压变频器控制泵群沿此曲线运行调节流量与压力，满足用户需求且没有多余扬程，千吨水电耗降低了7.62～10%，管网末端服务压力精度±0.002MPa。 关键词：高压变频器；水泵；变流变压曲线； Abstract: Construct a water variable flow and pressure curve model for water supply SCADA system data based on, curve at any point of the factory pressure adjusted with the changes i[登陆后可查看全文]
