Electromagnetic transient simulation of induction machine based on QSS algorithm

This paper explores the feasibility of transient simulations power system based on discrete event system (DEVS), where the Quantized State System (QSS) algorithm is used for numerical integrations. An induction machine model based on DEVS formalism is built up. Moreover, to guarantee the efficiency and accuracy of transient simulations based on QSS, an algorithm for optimal selection of quantum is derived. Test results with comparisons with traditional EMTP simulations are presented, which also validate the proposed simulation method.
