Fast Start System for a 200-KW Gas Turbine Generator Set

Emergency standby generator systems require rapid start characteristics capable of providing on-line operation within 10 seconds under a wide range of environmental conditions. This paper describes the design and development of a fast start, air impingement system for a 200-kW, single-shaft, gas turbine generator set. The conventional electric start system was replaced by a high pressure, air start system which reduced the total start-to-load time from 21 to 9 seconds.
