Modelling of power systems in Omola for transient stability studies

It is illustrated how the universal, equation-based, and object-oriented modeling language Omola facilitates modeling and simulation. The application is modeling of power systems for transient stability studies. However, the intention is not to develop a full-fledged power system mode, but to illustrate general ideas with concrete examples. The focus is on structural issues of model decomposition, which give flexibility. Model component shells with well-defined terminals which can be easily used to define models of different complexity through inheritance are developed. These model components have been used to implement a 16-machine power system model of the Scandinavian power grid. Simulations agree very well with results obtained from ABB's package Simpow.<
