Original Abstract

The article deals with the issue of frequency measurement in PSCAD software. The objective is to assess frequency waveform in buses of the grid calculated by PSCAD when outage of one generator occurs. Two simulations respecting different electrical distance between buses were accomplished. Simulation results show the correct assessment of the influence of electrical distance between buses, however inaccurate calculation of frequency comparing to speed of generators. The main contribution is to point out that frequency calculated from voltage waveform can be incorrect, which can cause false operation of protective relays.
