Ring capacity assignment optimization is very important for planning a SDH/SONET Bidirection Self Healing Ring(BSHR). But at the present, there is no efficient algorithms in the world. In this paper, a new algorithms of ring capacity assignment optimization for SDH/SONET Bidirection Multiplexing Section Protection Ring(BMSPR) is presented. This algorithms which is based on shortest routing circuit demand matrix is very efficient for capacity equilibrium optimization when planning BMSPR. The simulation results demonstrate that the ring capacity requirement can be dropped to sixty percent of original capacity requirement, this will make less project investment and make high utilization ratio of circuits and equipment.

Simulation of power electronic motor drive system by modified nodal method is realized, and a simulation model of induction motor is presented on the basis of the Park equation. The dynamic model of induction motor under α β reference frame is approximated by its associated discrete circuit model with the trapezoidal algorithm, after linearized using the Neoton Rapson algorithm, the contribution of induction motor model to the circuit's nodal equation matrix is calculated. This model makes it possible to treat the complete power electronic main circuit and motor system together, and it is suitable for analyzing any induction motor drive circuit configurations with arbitrary conduction patterns. This model is verified by simulation results.
