DYNAMIC ANALYSIS OF WIND FARM OPERATION INTEGRATED IN POWER SYSTEM BASED ON SYNCHRONIZED MEASUREMENTS

Reliable and safe control of the power system is based on knowing current and voltage conditions during normal and irregular states. Real time dynamic disturbance responses, caused by characteristic events, are especially important. Wind farm Vratarusa is currently the only wind farm connected to the Croatian transmission system. This paper focuses on the impact of the wind farm Vratarusa on the system in the transmission area Rijeka. Static calculations (power flow calculation and short circuit current calculation) and dynamic analyses (transient phenomena) comprise normal, irregular and outage operational states, as well as their impact on a protection system and on overall power system stability. Analyses are based on a mathematical model of the transmission system area Rijeka, verified by synchronized voltage and current phasor measurements.
