Steady-State Value Computing Method to Improve Power System State Estimation Calculation Precision

With the respect to the inaccurate and divergence results shown in practical operation, the current researches focus on bad data and synchronous precision. Considering the precondition of state estimation, a new computing method was proposed for steady-state value calculation. The power system online measured data based on SCADA is analyzed through mathematical modeling. The theoretical analysis is simulated by using MATLAB/SIMULINK software, and it can provide an effective way to improve the precision of state estimation in practical operation.
