Phasor Measurements Application in Power Systems for Accelerated Power Flow Calculations in Emergency Control

Abstract:

Power system’s voltage phasor (phase and amplitude) measurements provided by phasor measurement unit (PMU) gives opportunity to build the algorithm of PMU assessment generating triangular admittance matrix. It allows reducing of the power system power flow calculation to the sequential solving of single equations with one variable at a time, instead of conventional linear equations system solving. The effect of super accelerated calculation is important for on-line operative calculations and for emergency control systems with pre-selected settings. This paper considers the general features of the algorithm. The paper presents test results obtained from the IEEE power system models and big power systems for more than 3000 buses. The PMU and SCADA concurrent use was concerned.
