Abstract: This paper presents a new sparse formulation for the solution of unbalanced three-phase power systems using the Newton-Raphson method. The three-phase current injection equations are written in rectangular coordinates resulting in an order 6n system of equations. The Jacobian matrix is composed of 6/spl times/6 block matrices and retains the same structure as the nodal admittance matrix.

DOL starting: In the DOL method, we directly switch the stator of the three-phase squirrel cage induction motor on to the supply mains. The motor at the time of starting draws a very high starting current (about 5 to 7 times the full load current) for a very short duration. The amount of current drawn by the motor depends upon its design and size.
