## 基于PSAT的配电网电力系统潮流计算

AbstractPower system steady state includes the analysis of power flow calculation and static security analysis. The power flow is mainly introduced in this paper. Power flow calculation is the basic method of planning, operation of the power system,  with the development of modern power system,  and the system of strong nonlinear multi element characteristics have become increasingly prominent, the amount of calculation and the computational complexity increased dramatically. In the calculation of processing trend, the speed of the computer software has been unable to meet the requirements of large power system simulation and real-time control, and study the related software flow problem has become the key to efficient simulation of large scale power systems. With the continuous development of computer technology and mature, the computation of MATLAB power flow has opened up new ideas for solving the problems of large power grid simulation technology, with fast. Power flow calculation is the most basic operation design and operation of the power network, the power network of various design schemes and different operation mode for power flow calculation, can get the voltage of each node of the grid, power loss and the power flow and network element in the, and then obtain the power loss.

PSAT flow calculation software is based on MATLAB, with a graphical user interface based, set drawing, analysis, calculation and data management as one of the free software. First, a brief overview of the PSAT functions and features, combined with the two tidal current calculation results indicate that the key problem of establishing the model, parameter setting of the power network, and finally get  the correct results.
