Given the power system network structure, parameters and decisions operation of the power system boundary conditions, to determine the method of operation of the power system is one of North Korea flow calculation.PQ deposition method is the form of polar coordinates Newton the widening trend of a simplified calculation method. PQ deposition method adopted by the specific characteristics of the power system analysis, Newton’s Law of the Jacobian matrix formula has effectively simplified and improved. As a result of these simplified formula that involves only the coefficient matrix, the balance of power has not changed node equations and the convergence criterion, because the results will not reduce the accuracy.MATLAB is an interactive, objectoriented programming language, widely used in industry and academia, mainly for matrix calculation. Using iteration, the amendment through the establishment of matrix iterative equation to turn, gradually moving towards a true value to calculate the voltage electricity grid, power distribution.Use MATLAB software programming, saving memory to a large extent, reduce the amount of putation. By this calculation we understand that a number of engineering calculation and solve engineering probl
