J. Eng. Gas Turbines Power 140(12), 121009 (Oct 24, 2018) (9 pages) Paper No: GTP-17-1237; doi: 10.1115/1.4040690 History: Received June 29, 2017; Revised June 27, 2018

To provide pregiven quality ratings of control processes of maximal speed deviation and transient process duration is an important task for diesel generators. Calculation study of methods intended for improving transient process quality is carried out using mathematical dynamic model of diesel engine and control system. Dynamic operation modes of turbocharged engine differ considerably from static ones. Experimental study of one-cylinder diesel engine was conducted with transient condition simulation to validate approaches to the development of engine dynamic model. Based on the study results, mathematical model and computer program to calculate transient processes were developed. Calculation study of methods intended for improving diesel-generator control processes was performed using the computer program.
