  • Publication number: 20200386209
    Abstract: The present invention relates to a method for screening a correlated seed turbine for wind direction prediction. The method includes the following steps: (1) modeling a yaw event of a wind turbine based on a wind direction, a wind speed and a yaw parameter, and obtaining a wind turbine yaw event flag of each wind turbine in a wind farm during a modeling period; (2) classifying and counting the wind turbine yaw event flag, and obtaining a yaw correlation coefficient of other wind turbines each with a target wind turbine in the wind farm; and (3) screening a seed turbine based on the yaw correlation coefficient. Compared with the prior art, the method of the present invention has the advantages of high discriminant validity of the seed turbine, small error, high correlation, and close wind speed characteristics.

  • Publication number: 20170170856
    Abstract: A cloud SIM (Subscriber Identity Module) card pool system includes at least one SIM card pool device having multiple card slots for storing different physical SIM cards, an SIM card pool management center, and at least one terminal communication device. The SIM card pool management center selects optical communication paths to distribute SIM card data corresponding to the physical SIM cards to terminal communication device according to a distribution strategy and the state of the terminal communication device, and distributes multiple optimal communication paths when the terminal communication device are communicated with the SIM card pool device. The terminal communication device reports the current state to the SIM card pool management center, obtains the best matched SIM card data distributed by the SIM card pool management center, visits an authentication algorithm of a corresponding physical SIM card through the optimal communication paths, and obtains the corresponding answer data.

  • Publication number: 20110137939
    Abstract: Using the way of destruct, the complex system is split into several different qualitative elements (the definition of indicator, the definition of database, the definition of scheduling, the definition of check way, etc.). Each element has its special concept. Combing different elements organically, a completely certain meaning indicator-checked incident is produced, and it is possible to finish the expected indicator-checked task flexibly. In the case of the check fails, due to the pre-warning it is possible to perform the manual intervention in time.
