智能建筑谐波问题研究

Study on Harmonic Problem of Intelligent Building

智能建筑产业是随着信息产业的发展而诞生,且迅速发展起来的.现代建筑物的电气发展经历了电气化阶段、自动化阶段和当今的智能化阶段.随着小区和建筑楼宇智能化的兴起,以及信息处理技术的普及,智能建筑中广泛使用电子设备,其非线性产生的谐波电流,如果不加以抑制将严重影响电能的质量.笔者首先介绍了谐波产生的原因和其危害,然后阐述了谐波的测量技术,最后结合某工程实例对谐波抑制方法进行了分析和讨论.

The intelligent building industry is emerged and rapidly developed with the development of information industry.The electrical development of modern building experience three stages.The three stages are respectively electrification stage,automation stage and today＇s intelligent automation stage.With the rise of intelligent building construction and popularization of information processing technology,electronic devices are extensively used in intelligent building.Harmonic currents are produced by its nonlinear.The quality of power will seriously affected if harmonic currents are not suppressed.In this paper the causes of harmonic and its hazards are described firstly,then the harmonic measurements are described;lastly the harmonic suppression method has been analyzed and discussed based on some engineering example.
