摘要
主要对GB 50227—2008《并联电容器装置设计规范》中发生谐振的电容器容量公式进行了分析。在对并联谐振分析的基础上推导出发生谐振的电容器容量公式,并提出在不同的条件下公式存在的3种情况,但从实际工程的运用、标准的规范性和电力系统运行的安全性等方面认为国家标准中给出的并联谐振电容器公式应该在限制条件下使用。对推荐的公式进一步说明了使用时需要的注意事项,并通过案例论证了推荐的公式,目的是为从事无功补偿设计的技术人员参考,并供标准制定单位人员借鉴。
In this paper, the capacitor capacity formula for resonance in GB50227 Design specification on shunt capacitor is mainly analyzed. The capacitor capacity formula is derived on the basis of shunt resonance analysis, and three cases for existence of the formula at different conditions are proposed. But it is thought that the formula for shunt resonance capacitor given in the two national standards shall be used under limited condition in terms of a practical engineering application, specification normalization and safe operation in power system. The cautions for formula recommended by the authors are described in the application, and the formula is illustrated by cases with purpose of providing reference for those who are in the reactive compensation design and who are formulating the standards.
