"Synchronized at the Load''-III System tests and operating connections

Abstract

System test results, operating connections, and experience with the New York City system synchronized at the load are given. Data obtained by test are presented, showing the behavior of the system when generators are operated synchronized only through a low-voltage a-c. secondary network. The adaption of this method of connections to the New York City 60-cycle system, including system layout, station and feeder arrangement, and automatic recording apparatus is described. Experience with these connections has demonstrated that stable performance of prime movers is obtained, load and wattless control is simplified, oil circuit breaker duty is reduced, and voltage fluctuation at customer's service during system disturbances is materially decreased.
