Use of Variable Frequency Drives as Energy Savers 使用变频驱动器作为节能装置
发布日期: 2009-11-01
绿湾水务公司(GBWU)决定实施一项基本改善项目 提高他们原水泵站的抽水能力。计划安装800马力(hp)的水泵,这些水泵将排入两条供水干管中的一条 将原水输送至GBWU处理设施。该系统由原水组成 位于湖面的泵站,将水泵输送至位于河流高点的水处理厂 社区这背后的理由是要确保社区消耗的水 在通往污水处理厂的途中,仅泵送一次。了解了这一操作需求,it 最重要的是确保原水供应泵送系统及其运行 尽可能地节能。 本文详细介绍了公用事业公司的操作方法,这将 通过评估电力的利用率,每年减少超过1000000千瓦时 变速驱动器可在季节性变化的峰值电力需求时间和 仍能满足需水量和流量。包括数字。
The Green Bay Water Utility (GBWU) decided to implement a capital improvement project to increase their pumping capacity at their raw water pump station. Eight hundred horsepower (hp) pumps are planned for installation, which will discharge into one of two water mains that will convey the raw water to the GBWU treatment facility. The system consists of the raw water pump station at lake level, which pumps to the water treatment plant at the high point of the community. The reasoning behind this was to be sure that the water consumed by the community is pumped only once, enroute to the treatment plant. Knowing this operational requirement, it became most important to ensure that the raw water supply pumping system and its operation was as energy-efficient as it could reasonably be. This paper expands upon the utility's approach to the operation, which will result in a reduction of over 1,000,000 kWh per year by assessing the utilization of the variable speed drives to work around the seasonally changing peak electric demand times and still meet water demand flow rates. Includes figures.
