Research on outstanding problems in the operation of wind farms. Generally speaking, the current operation of the wind power station is good, and the shortcomings are summarized as follows. (1) The type of fan is mainly based on double-fed fan and supplemented by asynchronous fan. The double-fed fan achieves variable frequency constant speed with its superior performance, which is more conducive to the stability of the power grid than the asynchronous fan. At present, the wind farm is dominated by doubly-fed wind turbines, but a certain proportion of asynchronous fans are still in operation. It is decided that the research on the operation of wind power must take into account the current situation of the two types of wind turbines. For each of the two types of wind turbines, separate mathematical models should be established for simulation analysis. (2) The maintenance work of the fan is complicated. Through research, Zibo electric drum found that the maintenance of the fan mainly includes the oil leakage problem of the fan, the heat dissipation problem of the gear box, and the replacement of the spare parts. Since the imported doubly-fed fan can flexibly realize the pitch angle adjustment and the inverter exists, the structure of the fan is more complicated, and the problem brought about by this is that the replacement of the spare parts is prominent. For domestically produced asynchronous fans, the leakage problem is relatively serious due to limitations in the process and other aspects. Some fans require the manufacturer to regularly clean the oil on the fan column and increase the operation and maintenance costs.
