| Popis: | Measurements of parameters in electricity grids arefrequently captured as average values over some time interval.In scenarios of distributed measurements such as in distributiongrids, offsets of local clocks can result in misaligned averagingintervals. This paper investigates the properties of the so-calledtime alignment error of such measurands that is caused byshifts of the averaging interval. We extend a previously derivedMarkov-modulated model and provide an approximation ofthe variance of the time alignment error. The model accountsfor slow-decaying correlation structure found in actual tracesof electrical measures. We compare results of three electricalmeasures for 20 traces with numerical results and simulationsfrom the the fitted Markov model. |
