Steady-state power flow calculation belongs to power system steady-state analysis, and the data used in calculation should be steady-state data. However, the existing SCADA system hasnt distinguished the transient data from the steady-state data. The real-time measured data reflect the dynamic electric power system. It is the right reason for not all of the real-time measured power can be used for power flow calculation. In another word, it causes the matching problem between measured data and power flow calculations. Based on the current situation of information collection system, the characteristics of the measured data had been analyzed in this paper. And an effective acquisition method for steady-state measured data is proposed on the theoretical basis of the law of large numbers. It uses the average value of the measured data that in the same load state to approximate the steady-state true value in one period. And the steady-state data can be used in power flow calculation. The simulation results show that the method proposed in this paper ensures the accuracy and reliability of power flow calculation.

Optimization of Power System Development Using Acceleration Factor for Power Flow Calculation The dynamic optimization process is analyzed from the viewpoint of simplifying the power flow calculations. The aim of the work was to reduce the calculation time using all admissible algorithms. Although the conventional iteration methods are simple and fast enough, the use of the so-called relaxation principle leads to increased calculation time. The paper exemplifies the power flow calculation based on the iteration method using acceleration factor. Proposals concerning the modelling of a power system are put forward in the aspect of its future development.
