Selecting the proper size capacitor bank for power factor correction at a pulp mill, with an existing capacitor bank in service, requires many hours of computer modeling and system simulations. This article discusses the calculations involved in specifying the capacitor bank and evaluates the system response to transient switching events involving the two capacitor banks. Finally, it provides a comparison of the results of the calculations with field measurements recorded during the commissioning of the new capacitor bank.

纠正磨机功率因数的项目：第二个电容器组的选择和部署

在现有的电容器组投入使用的情况下，为制浆厂选择合适尺寸的电容器组以进行功率因数校正，需要许多小时的计算机建模和系统仿真。本文讨论指定电容器组所涉及的计算，并评估系统对涉及两个电容器组的瞬态开关事件的响应。最后，它提供了计算结果与新电容器组调试期间记录的现场测量结果的比较。
