The Necessity of Redefining the Terms of Voltage Qualification Rate
Restricted by historic condition,before it sounded reasonable to measure the level of power quality and power voltage deviation by using power time T to define voltage qualification rate.Standing on the development of power grid and electric power metering technology,it is more scientific to use electric energy kWh to define the voltage qualification rate.Redefining the terms of voltage qualification rate could improve the electric power quality and reduce the electric power voltage deviation.
