The invention relates to two methods for preparing crystal I-type clopidogrel bisulfate, wherein the method 1 comprises the following steps that clopidogrel bisulfate is dissolved into normal propyl alcohol and an ether precipitation solvent is added to prepare the crystal I-type clopidogrel bisulfate after suspending, stirring, filtering and drying; the method 2 comprises the following steps that the clopidogrel bisulfate is dissolved into an alcohol organic solvent; a crystal I-type clopidogrel bisulfate seed crystal is added to prepare a suspension solution after stirring or ultrasonic processing; and the precipitation solvent is added to prepare the crystal I-type clopidogrel bisulfate after standing, filtering and drying. The powder X-ray diffraction analysis, the DSC (Dynamic Stability Control) analysis and the infrared spectroscopic analysis are carried out on the prepared crystal I-type clopidogrel bisulfate. The crystal I-type clopidogrel bisulfate with high crystal type purity ...

The invention provides a wind power plant sector management control method and device, and belongs to the technical field of wind power generation. The method comprises the following steps: acquiring a first fatigue load of each wind turbine generator in a wind power plant; based on a wind rose diagram of the wind power plant, determining a secondary wind direction sector and a main wind direction sector of the wind turbine generator with the first fatigue load exceeding a preset fatigue threshold value; and a target unit is selected from the wind turbine units with the first fatigue loads exceeding a preset fatigue threshold value, and power control is conducted on the secondary wind direction sector of the target unit according to a preset control rule. The wind power plant sector management control method and device have the advantages that the generating capacity of the wind power plant is further guaranteed, the wind turbine generator with the high failure rate is protected, and misoperation ...
