Simulation of arc models with the block modelling method

Simulation of current interruption is currently performed with non-ideal switching devices for large power systems. Nevertheless, for small networks, non-ideal switching devices can be substituted by arc models. However, this substitution has a negative impact on the computation time. At the same time, these simulations are useful to design switchgear. Although these simulations are for large power systems cumbersome with traditional modelling methods, the block modelling method can handle arc models for any size of networks. The main advantage of applying the block modelling method is that the computation of the analytical Jacobian matrix is possible and cheap for any number of arc models. The computation time is smaller with this approach than with the traditional approach.
