简析并联电容器装置在选型时应注意的问题
摘要
石油化工行业供电系统主要通过并联电力电容器来提供无功功率
但随着非线性负载的增多
大量谐波电流注入到供电系统中
造成对供电系统的污染。若并联电容器装置的配套设备设计选型不当
有可能与谐波电流共同作用引起谐振
造成设备损坏。针对以上问题
对并联电容器装置在选型时应注意的问题进行了讨论。
Abstract
In the power supply system of petrochemical industry the reactive power is mainly supplied through shunt capacitor. But with increase of non-linear load
a large number of harmonic currents are injected into power supply system
thus causing pollution to the power supply system. If the design selection of the complete facilities for the shunt capacitor is not appropriate
it probably acts together with harmonic current and leads to resonance and equipment damage. For above problems
the attention on type selection of shunt capacitor is discussed.
