Squirrel cage induction generators are frequently applied to small to medium-sized hydro power plants, because of theirsimple and rugged structure, low construction cost and easy maintenance. Therefore, it is expected that induction generators will beused more and more in hydroelectric power generation in the future. The biggest problem in the application of induction generators isthe large inrush current at the grid connection. This inrush current is large enough to equal the current flowing at the start of the motor,causing a voltage drop in the connected distribution system. Therefore, the range of voltage fluctuation is specified differentlyaccording to the generator output. This paper is the result of a study on the capacity range of induction generators that does not exceedthe allowable range of voltage drop in the distribution line.
Abstract

This inrush current is large enough to equal the current flowing at the start of the motor,causing a voltage drop in the connected distribution system. Therefore, the range of voltage fluctuation is specified differentlyaccording to the generator output. This paper is the result of a study on the capacity range of induction generators that does not exceedthe allowable range of voltage drop in the distribution line.
