Modeling and Simulation of Diesel Electrical Aggregate

In the paper modeling and simulation of diesel motor with speed control system and generator with voltage system as complex nonlinear and multivariable systems are presented. Mathematical models for every part of diesel aggregate (diesel motor, synchronous generator, brushless exciter, voltage controller, speed controller and load) are developed and afterwards connected in common model of aggregate. Dynamics of diesel motor is described by second order equation, ignoring turbocompressor, inlet and outlet collectors, while synchronous generator is described in d,q coordinating system with saturation taken in d-axis. For brushless exciter model according to IEEE, Vol. PAS-100, No. 2, Feb. 1981 is used. The load is also described via d,q coordinating system. Upon these mathematical models of the aggregate, simulation model is made using "MATRIXx" simulation software package. Since experimental results match results of simulation in high degree, this model is privileged for selection of diesel electrical aggregate's type and for analyzing quality of load feeding.
