Popis: Power system should adjust the supply capacity power by load fluctuation. This paper has been examined the frequency fluctuation and system stability against the intermittent fluctuation of the industrial load. Load fluctuation should be examined the effects on the power supply service in the power system. The load fluctuation would be a factor that increases the reserve power. In order to reflect, the system has been analyzed according to period, season and load level. The method has been analyzed load fluctuation to power system frequency by using the Fourier transform. It has been calculated the power capacity operating by load fluctuation of short period, seasonal and load level. As a result of frequency analysis for the load fluctuation, the reserve capacity power was needed to the short period than the load capacity calculation according to the load fluctuation time used in the power system. The maximum fluctuation rate has been shown in the off-peak load and fall seasonal load of 208%. The minimum fluctuation rate has been shown in the mid-peak load and in the winter seasonal load of 35%. It could be considered which should be analyzed the effect on the power supply service and suggest countermeasures against system instability.
