Abstract

Accurate calculation of switching events is important for electromagnetic transient simulation to obtain reliable results. The common presumption of continuous differential state variables could prevent the accurate calculation, thus leading to unreliable results. This paper explores accurately calculating switching events without presuming continuous differential state variables. Possibility of the calculation is revealed by the proposal of related methods. Feasibility and accuracy of the proposed methods are demonstrated and analyzed via numerical case studies.
