Abstract


With the enlargement of the wind scale, the negative effects of wind power became more and more serious, and turn to be great obstacle of the further utilization of the wind resource. In the paper, a simulation model of a wind farm based on variable speed constant frequency double-fed induction generators (DFIG) was set up using the electro-magnetic transient simulation software EMTP_RV, and the voltage harmonics was analyzed at the common connection point where the wind farms were connected to the grid. Various possible situations were investigated, such as different wind speeds, the presence or absence of system background harmonics, and three phases unbalanced and balanced system voltage, and according to the simulation results, put forward the solutions and measures to solve the problems. The researching work has an important theoretical meaning and pragmatic value for the programming, designing, and operation of the wind farms in the grid.
