【摘要】 分析了大庆油田热电厂锅炉送、引风机电机加装非线性变频器后对电能品质的影响,即通过对比变频器在工频、变频两种运行方式下,不同等级电压母线测得的电压、电流、谐波数据,了解了非线性变频器运行时产生的谐波,对供电电源电能质量影响很小,对电能品质影响是有限的、可控的。换句话说,锅炉辅助机加装非线性变频器是可行的,既节能,又不影响电力系统稳定性。更多还原

【Abstract】 The effect on the quality of electric energy in Daqing thermal power plant be analysis,FDF and IDF with nonlinear inverter,by contrast,frequency inverter in the frequency of two kinds of operation mode,the voltage,current,harmonic measurement data of different grades of voltage bus,the harmonic generation nonlinear inverter operation,on the power supply quality of electric energy has little effect on the quality of electric energy,the impact is limited,controlled. In other words,nonlinear inverter installed boiler auxiliary equipment is feasible,energy saving,and does not affect the stability of power system.更多还原
