Hardware Design Of Diesel Generator Sets' Digital Control System

With the development of the theory of Automatic Control, Micro Electric technology, special integrated chips and Power Electronics technology, the application of Generator Sets control theory is widely extended in practice. Generator Sets controller is improved into Digital Controller with optimal capacity and simple structure, instead of the traditional analog controller.For there are lots of Generator Sets, which power electrically-driven rigs, used on oil platform in the country, the modification of the control system of Generator Sets is more and more. On the background, the principles of Generator Sets digitalized control system based on DSP, the whole process of design and system structure from the view of hardware design are presented in this paper. The main chip is 16-bit fixed-point DSP TMS320LF2407A specially designed for control system by TI Inc. The controller has high-performance processing capabilities, abundance on-chip and outside-chip peripherals, so that it can meet the need of Generator Sets' real-time control and performance requirements. Integrated digital voltage regulation, digital governing, and generator set protective functions into one single control system provide enhanced reliability and performance compared to conventional control systems. The selection of the control system and its hardware design, the programming of the functions of GALs and validation of the controller based on DSP by Hardware-in-the-Loop system are accomplished in this paper.
