The main content of this article is based on simple network power flow calculation of design, combined with the Newton - Ralph method flow calculation, the PQ fast decoupled power flow calculation program, complete the power system flow calculation based on the C language program design.In the case of a power system in normal operation, through to the trend of the power system (power, voltage, phase Angle, etc.) to the power system network operation state of a particular point in time is described.In this paper, based on the above basic knowledge of network power flow calculation for power system with the design, simulation, and analyzed the result precision of two calculation methods in different scenarios.
