Cooperative Work of Step Voltage Regulator and Static Var Compensator

In recent years, a power supply with small capacity that is called “Distributed Generators (DGs)” has got much attention, and is being used to a distribution network system. The main backgrounds of this are liberalization of electricity market and the growing concern with the environment. Besides, more and more powerful electricity quality control is requested as progress of an information-oriented society. In this paper, the authors propose a cooperated work of voltage management machinery. The paper concerns with an
