摘要
随着电网规模及容量的不断扩大,由内外部因素导致的电网电压晃电会造成变频器欠压保护退出运行,导致电机停机、生产中断,给企业造成较大的经济损失和安全事故。为减小晃电给企业造成的不利影响,设计一种新型变频器抗晃电装置。
the power grid voltage fluctuations due to internal and external factors, there will be a short period of time, cause the inverter lose power and the motor stopped. This situation may bring unnecessary trouble, also caused economic losses to the enterprise, in order to reduce the adverse effects caused by shaking power, design a device based on PLC to improve the ability to resist frequency converter.
