Conceptual methods of starting and controlling operating modes of compressorless combined cycle gas turbine unit

A method for operation study of a compressorless combined-cycle gas turbine (CCCGT) unit during transients from one steady-state mode to another, including start-up and shutdown, is proposed. As an example, studies the energy complex with capacity 60 MW are given. variant algorithm concept start/stop such This includes algorithms starting three initial states (cold, hot standby). For these algorithms, time consumption characteristics estimated. It shown that cold state, can be started brought nominal in 1.5-2 hours. At same time, costs will not exceed its own needs mode. The state reduced 20-25 minutes, standby 2.5-3 minutes. proposed control transient modes such, so temperature main components parts provided at constant temperature. Thus, determined only by speed regulatory authorities. Consequently, power systems operating on CCCGT cycle operate equally efficiently, both basic
