摘要
GB/T 14549—93与IEEE std.519:2014两标准中分别针对用户可注入公共连接点的谐波电流限值进行了规定。但2个标准中所提出的限值在确定方法及工程使用中皆存在一定差异。在修订过程中的谐波国家标准GB/T 14549拟采用IEEE std.519:2014中单个用户的谐波电流发射限值,因此其谐波电流限值确定方法的合理性有必要充分讨论。首先阐述了2个标准中有关谐波电流限值的相关内容,并对其确定方法分别进行了推导与探讨。最后通过具体算例的结果对比,分析了二者的异同。
The allowable harmonic current limits injected to the common connection points are stipulated for users respectively by GB/T 14549—93 and IEEE std.519:2014.However,there are some differences between two standards in determination methods and engineering application.The harmonics national standard GB/T 14549 under revision intends to adopt the emission limits of harmonic current for single user in IEEE std.519:2014.Therefore,it is necessary to fully discuss the rationality of the methods for determining the harmonic current limits.In this paper,the limits of the harmonic current in two standards are introduced,and their determination methods are deduced and discussed respectively.Finally,the similarities and differences between them are analyzed through case study.
