  ABSTRACT: This paper deals with an approach of dynamic modelling for shipboard electric network. The model developed describes the whole system's behaviour in both steady and transient states. The first step to build the simulator is defining a common frame, then each network's component is modelled in this frame and finally the whole system's model is built thanks to the relations connecting the different state vectors. Moreover, in order to compare the simulator's steady state results, a macroscopic modelling approach based on the resolution of the power flow problem is presented. This model highlights the advantage of the developed simulator since it reproduces the transient behaviour of the system. The dynamic simulator developed under MATLAB/Simulink is a powerful tool which allows studying the system's behaviour in both steady and transient states. It can be used to predict network's behaviour and also as software benchmark for stability or control studies.

  ABSTRACT: In embarked networks: aeronautics, naval ..., the power is not infinite contrary to the classic energy distribution network. This paper deals with a general approach of embarked network modeling. The model built leads to a simulator which allows predicting network's dynamic behavior in both transient and steady states. It allows highlighting various phenomena which can appear in the network (desynchronization, ...). Moreover, in view of voltage and frequency control, a second modeling approach based on identification is used to synthesize voltage and frequency regulators
