摘要
Abstract
The transient stability of sending power gird containing high proportion of wind power is researched.The model structure of variable speed constant frequency (VSCF)unit and its impact on power grid transient stability are analyzed theoretically; using measured data of short-circuit experiment of wind farm the accuracy of simulation model of VSCF unit and that of simulation results are verified; the impacts of different operation modes,different positions where faults occur and the ratio of power generated by thermal plants to that generated by wind farm are analyzed and it is pointed out that as for the stability level of sending-out transmission line in sending power grid the impact of wind farm power output on its stability level is less than that of power generated by thermal plants,however the stability level of outgoing lines of thermal plants inside the sending power grid mainly depends on thermal plants themselves,and to analyze the impact of wind power output on stability level of outgoing lines of these thermal plants the impacts of such factors as grid structure and operation modes should be taken into account.关键词
