| 采用专门的滤波装置能够有效的滤除高次谐波，同时向电网提供容性无功功率，其重要性主要表现在以下方面： The importance of using special filter devices to effectively filter high-order harmonics and provide capacitive reactive power to the power grid is mainly manifested in the following aspects: 滤除高次谐波能够定化用电环境，降低视在功率，减少谐波电流在用电设备和输配电设备中的发热，直接节省有功功率；消除由于谐波产生的震动，延长电器的使用寿命；有效的消除对敏感元件的影响。 Filtering high-order harmonics can fix the power environment, reduce apparent power, reduce the heating of harmonic current in power equipment and power transmission and distribution equipment, directly save active power, eliminate the vibration caused by harmonics, prolong the service life of electrical appliances, and effectively eliminate the impact on sensitive components. 由于滤波回路是由电抗器和电容器串联形成的，所以在滤波的过程中能向电网注入容性无功，提高了功率因数，这样就能避免供电部门高额的功率因数调整电费，由于无功电流的抵消，也相当于提高了配电设备的容量，减少了线损。无功功率补偿还能提升末端的电网电压，对优化用电环境有很重要的意义。 Because the filter circuit is formed by series connection of reactor and capacitor, capacitive reactive sanreqi.07858.netchenbanmc.07858.net zhushiban.07858.net jiareqi.07858.net chuyouji.07858.net ruhuajii.07858.netpower can be injected into the power grid in the process of filtering, and the power factor can be increased, so that the high power factor adjustment charges of the power supply department can be avoided. Because of the counteraction of reactive current, the capacity of the distribution equipment can be increased and the line loss can be reduced. Reactive power compensation can also improve the terminal voltage of the power grid, which is of great significance for optimizing the power environment. |
