摘要
电网中某些设备和负荷的非线性特性导致电力系统的正弦波形畸变,由此产生谐波。谐波对电网的安全与经济运行及用户的安全生产、产品质量和电器设备的安全与寿命,都有重要影响。本文用瑞丰钢铁公司实例阐述了无源滤波装置的设计思想,并检验仿真结果的正确性。滤波装置投入运行后,不仅提高了功率因数,而且也滤除了谐波,使谐波含量满足国标要求。
The nonlinear characteristic of some equipments and loads lead to the sine wave distortion in power system, thus causing harmonics. The harmonics has influence on the safe and economic operation of power grid, the safe production of users, the quality of products and the safe operation as well as life time of electric equipments. This paper presents the designing ideas about the passive filtering device, and tests the correctness of simulation results. After the filtering device in operation, not only improves the power factor, but also filter out harmonics so to meet the requirement of national standards.
