Error Analysis of Wide Area Measurement Based Measurement Power Flow

Abstract:

Measurement take place of calculation is an advantage of wide area measurement based measurement power flow, but its accuracy needs to be explored. This paper points out the measurement power flow’s data dose not conform to the actual power flow’s data on condition of phase angle measurement exist error. Through the analysis of example we can see that the deviation of active power will reach 15% when phase angle exist 0.1°error, its accuracy is worse than DC power flow in engineering calculation .This paper suggest using the phase angle value which was measured as initial value in power flow calculation, it will reduce the error’s impact on power flow calculation.
