摘要：

There is a problem that the low-voltage ride-through measures of a hybrid wind farm are complex and difficult to cooperate with and the fault characteristics after low-voltage ride-through are difficult to analyze. Thus it is proposed that a resistance-capacitance crowbar is applied to the doubly-fed wind turbine to improve the frequency offset and reactive power characteristics of the hybrid wind farm during low-voltage ride-through. First, the models of doubly-fed wind turbine group and permanent magnet direct-drive wind turbine group are established, and a simplified equivalent model of a hybrid wind farm is established by the method of grouping and aggregating equivalence. Then the reactive power regulation ability and regulation characteristics of various types of wind turbines during a fault in the hybrid wind farm considering the resistance-capacitance crowbar are analyzed. The reactive power cooperative control strategy of the hybrid wind farm is formulated to optimize the reactive power output capacity during low voltage ride-through. The short-circuit characteristics of the hybrid wind farm after adopting the cooperative control strategy are analyzed and the short-circuit current is analyzed. Finally, based on PSCAD/EMTDC simulation software, a hybrid wind farm simulation model is established to verify the effectiveness of the collaborative strategy and the correctness of the fault current expression. © 2024 Power System Protection and Control Press.
