Series Synchronous Condensers for Generation of Voltage Consumed by Line Inductance

The factors determining the power-carrying capacity of a transmission system are briefly discussed in this paper. The principal effects obtained by the operation of synchronous condensers used to compensate for the system consumption of lagging reactive kv-a. are pointed out. This method of compensation is contrasted with the direct method of supplying the reactive kv-a. to the line in the manner in which it is consumed, i. e., by the series method. A plan for obtaining direct or series reactive kv-a. compensation by a method employing electric machinery is described. This includes a description of a method for producing the required voltage and inserting it into the system. Some of the characteristics of operation and advantages to be gained by the use of the described method are given.
