Development of an analysis system for voltage dip measures

The voltage dip has been a problem from the increase of the customer loads such as an electronics devices etc. and the electric power quality needs. This paper shows the voltage analysis system for the customer including dip measures. The first characteristic of this system is to predict the voltage dip performance of customer loads and the effect of voltage dip measures applied to loads conditions. And the second characteristic is to take the load rejection characteristic of the customer loads into account. The voltage dip measures can be arbitrarily selected from measures such as dynamic voltage restoration and the converter system with batteries etc.
