当前人们是否可以正常使用家用电器的问题之一就是建筑电气中的谐波问题,谐波不仅对人们的日常生活产生影响,同时也会对用户的身心健康产生影响,假如我们不能对各种非线性负载产生的谐波进行及时的抑制,将会对人们产生很大的影响。本文首先简要地介绍了谐波的相关基本知识,然后主要介绍了建筑电气谐波的两种简单检测方法。最后本文用Simulink对检测谐波的方法搭建了仿真的模型,最后的结果说明了该方法对建筑电气中的谐波具有很好的检测效果。
At present, one of the problems of whether people can use household appliances normally is the harmonic problem in electrical construction. Harmonic not only affects people’s daily life, but also affects users’ physical and mental health. If we can not influence on various kinds of non- The suppression of the harmonics generated by the linear load in time will have a great impact on people. This paper first briefly introduces the basic knowledge of harmonics, and then introduces two simple methods of detecting building electrical harmonics. Finally, this paper simulates the method of detecting harmonics with Simulink, and the final result shows that this method has a good detection effect on the harmonics in electrical construction.
