Summary: Major system breakdowns experienced in our national grid and worldwide indicate that power systems are lacking of reliability, robustness and security. The actions has taken to avoidthe system breakdown and the inspections afterwards reveal the fact that the biggest cause of chain of disasters is again lack of technical knowledge. Frequency is one of the most importantparameters of an electrical power grid. In order to evaluate power system dynamics correctly and efficiently, frequency parameters are paramountly needed.Since many electrical generation and consumption points are synchronized with each other in interconnected networks, all changes in supply and demand cause fluctuations in thefrequency. In order to separate the occurring events which cause these oscillations in the frequency data from the normal conditions, the frequency data must be filtered and passedthrough an algorithm. In this study, the frequency dynamics are monitored effectively, recorded in the database in the appropriate format and with the developed algorithm the disturbances inthe network are detected. |
