| Summary: | As a renewable energy, wind power, most is anticipated to contributed a significant part of the generation in power systems in the future, but also bring new problems related to the integration of power quality, consisting mainly of voltage control and reactive power compensation. wind power generally dose not contribute to voltage control in the system. induction machines are mostly used as generators in wind power production based. induction generators used in wind turbines and wind farms consume a large amount of reactive power. next, since there is no voltage control of induction machines installed and draw reactive power from the power system, these machines are a source of of voltage fluctuations. therefore, a combination of wind turbines for power networks, especially the poor distribution network is one of the major concerns of power system studies. reactive power compensation and power quality in the poor distribution networks to connect the wind turbines are a big task for this thesis.this work was simulated using matlab / simulink for a weak distribution network and the integration of wind power in the network. without reactive power compensation of wind power in the network, the collapse of the system voltage and under voltage tripping of wind generators occur. for dynamic reactive power compensation, as statcom (static synchronous compensator) and capacitors are used at the point of interconnection of wind farms and networks, the system absorbs the generated wind power while maintaining its voltage level. as a result the study shows that, reactive power compensation by statcom and capacitor banks make it possible the combination of wind farm in a weak distribution network. |
