In a detailed dynamical analysis of SMES installed in power systems, it is important to coordinate the digital simulations for the slow dynamic model of multi synchronous machines and for the fast dynamic model of SMES in which the commutation characteristics in converter can be included.
In this paper, a practical simulation method is developed for the aim to dual-time-scale modeling. Concurrent processes are built with parallel constructions of the phasor based numerical analysis for multi synchronous machines coupled through the network and the instantaneous voltage and current analysis for SMES and its converter system. The concurrent processes for a dual-time-scale simulation are realized by multi transputer network.
Proposed simulation technique is successfully applied to verify the experimental results obtained by a 1 MJ-SMES test system which has been developed at Tohoku Electric Power Company in 1991.
