Anti-disturbance Hamiltonian Model of Diesel Generator

The incremental negative damping characteristics of pulsed loads have adverse effects on the stable operation of independent power systems. The diesel generator set is the most important power source in the independent power system. It is necessary to conduct damping analysis on the generator and enhance the system damping by increasing the energy dissipation of the generator. Based on Hamilton realization, this paper analyzes the internal energy structure of the fifth order model of the generator in an independent power system with a pulsed load. A method to reduce the negative dissipation term in the generator energy dissipation is proposed to enhance the system damping and improve the robustness of the system. This paper verifies the proposed method based on PSCAD/EMTDC simulation. It provides a basis for the theoretical basis of the diesel generator sets in the independent power systems with pulsed loads.
