Wind-generator influence to the power quality in the coupling point to the distribution network

Abstract

The paper presents the results of analysis of wind-generator and their influence to the power quality parameters in the coupling point to the distribution network. The specified results should be used as a starting point for distribution system operators (DSO) for issuing permit for connecting renewable sources, mainly for wind-generators. As the case study, the results of measurements at the only one wind generator installed in Serbia, near town of Tutin, are used. The cases of wind-generator start and stop during low wind and consequently smaller value of the energy delivered to the network are particularly analyzed. Taking into consideration that law regulations in this field are not yet defined, EU standards and guidelines are used along with the newly adopted Technical recommendation No. 16 of Public Enterprise Electric Power Industry of Serbia.
