Voltage Sag Governance for Load Power Converter Line
摘要
Abstract
The supply quality is critically required for the sensitive load driven by converter devices. The voltage sag existing in power supply line may make the frequency conversion motors stop, which often causes economic loss by millions of dollars. A dynamic voltage restorer was developed in combination witb the governing experience for voltage sag of a wire drawing production line and the requirement of eliminating the hidden danger. The restorer adopts a split-phase compensation structure to carry out split-phase control and mutual independence operation mode of three inverter modules. The main circuit structure. parameter calculation and control method were studied and discussed in the development process of this equipment.关键词
