N2 - This report presents the results of investigations of active power variation influences on such parameter values of transients as voltage frequency at power supply networks and voltage phase at the same network. It was analyzed the main types of theoretical transfer functions and experimental ones for equivalent power system with thermoelectric power stations. Analyzed transfer functions correspond to mane types of regulators which are used for frequency regulation at power systems. Active power variations are represented as random processes with known parameters. The results of calculations have revealed that on the condition that peak-to-peak value of active power fluctuations in power networks no more than 0.1% of active power of equivalent power system generator, it is possible to neglect the influence of frequency fluctuations on voltage phase variations.
