Abstract	Voltage regulation of an alternator historically has depended upon variation of the field current, and high-speed regulators have been developed in order to improve synchronous stability. This paper describes a voltage control brought about by varying the output current. A reactive load is connected to the generator terminals. This load is varied electronically in such a way as to maintain the desired voltage and line current. Whereas regulation by field control is limited by the long time constant of the field winding, the electronic stabilizer acts upon the transient reactance and therefore it has the fast response needed to regulate the terminal voltage. The paper describes a new method for increasing the stability limits by supplementing present known methods and extending the limits of a-c power transmission. The electronic stabilizer is intended to take care of certain regulating functions which cannot be performed by a field regulator. The use of the two in combination, therefore, can be expected to yield still further improvement. No attempt has been made to compare this method with other methods of compensating the line and it is intended that these methods may be used in combination. Tests of a model equipment are described. A rough comparison has been made between this system and the use of series capacitors. Using present costs and parameters, the cost of the series capacitors was somewhat less. Further cost changes may alter this comparison, or there may be cases where series capacitors are not acceptable.
