采用谐波抑制整流变压器的新型工业整流系统
Novel Rectifier System Using Harmonic Suppression Rectifier Transformer
摘要
Abstract
Aiming at problems of harmonic suppression and reactive power compensation existing in the traditional industrial rectifier system,we put forward a novel rectifier system based on harmonic suppression rectifier transformer and its filter system.The new rectifier transformer adopts a three-winding structure,and its filter windings at the valve-side adopt unique zero equivalent impedance design and configure the related full-tuned filter equipment.Using the transformer filtering technology based on harmonic magnetic flux suppressing mechanism,the novel rectifier system can effectively restrain harmonic and compensate some reactive power at valve-side of the new rectifier transformer.Consequently,the effect of harmonic and reactive power on the rectifier transformer can be essentially resolved.Moreover,the connection scheme,harmonic suppressing mechanism and reactive power compensating principle of the new rectifier transformer and its filter system are analyzed.Thereby,the simulation model of novel industrial rectifier system is established.The simulation and on-site test results show that: compared with traditional rectifier system,the new system has excellent harmonic suppressing and reactive power compensating effects,and the harmonic content of the grid-side winding current of new rectifier transformer is greatly reduced;The power flow path of harmonic and reactive power in the system is changed so as to reduce the harmonic and reactive power loss,to improve power supply efficiency of rectifier system,and to realize energy saving and lowering consumption;In addition,the vibration and noise of rectifier transformer caused by harmonic current are significantly reduced.关键词
