探讨有源滤波在企业供电谐波治理中的应用

Discussion of Active Harmonic Filtering Applications in the Enterprise Governance of Supply

供电的波幅、频率、波形畸变等因素都会对电网质量产生直接影响,其中,发电厂控制供电的波幅和频率,而用电设备和负载则会对电流和电压波形的畸变产生影响。在企业生产过程中,使用的多为非线性负载,比如变频调速设备、整流器、不间断电源等,这些负载的电流波形与电网的正弦电压波形不一致,所以会产生畸变。由此可知,供电谐波会对供电质量产生不利影响,现针对应用有源滤波设备治理企业供电谐波的技术进行探讨。

The power factor amplitude, frequency, waveform distortion, and this will have a direct impact on the quality of the grid, where power plants amplitude and frequency control, and electrical equipment and load it Will have an impact on the current and voltage waveform distortion. In the production process, the use of multi-linear loads, such as frequency control devices, rectifiers, uninterruptible power supply, this sinusoidal waveform of the voltage waveform of the load current is inconsistent with the grid, it will produce distortion. It can be .seen, the quality of power supply harmonics will adversely affect existing applications to explore for active filtering device management enterprise supply harmonic techniques.
