Abstract: The present application discloses a computer program product, a method and an apparatus for yaw control of wind turbine generator system. The method for yaw control of wind turbine generator system includes: obtaining a real-time parameter of wind condition according to a predetermined length of time; performing vector analysis of the obtained parameter of wind condition to obtain a direction angle of prime wind energy; controlling yaw of the wind turbine generator system according to the direction angle of the prime wind energy. The employment of the computer program product, the method and apparatus for yaw control of wind turbine generator system provides relatively accurate data to the wind turbine generator system, improves the accuracy of the yaw of the generator system, thereby increasing the utilization rate of the wind energy.

Abstract: A method and device for monitoring a fault of a wind power generator set. The method includes the following steps: performing (101) fault identification on a component in a wind power generator set; and presenting (102) an identified fault using a three-dimensional model of the component. The device includes corresponding identifying module (61) and presenting module (62). By using the method and device, the fault monitor can intuitively observe the fault existed in the component, which not only is beneficial for taking effective fault processing measures before a minor fault evolves into a serious fault and thus reduces the harm of the fault, but also reduces the experience requirements for the fault monitor and avoids the process that the fault monitor in the prior art analyzes a two-dimensional curve to identify whether there is a fault in the component according to his experience.

Abstract: A process for combining the catalytic conversion of organic oxygenates and the catalytic conversion of hydrocarbons: an organic oxygenate feedstock is contacted with a Y-zeolite containing catalyst to produce a reaction stream, and a coked catalyst and a product stream are obtained after separating the reaction stream; a hydrocarbon feedstock is contacted with a Y-zeolite containing catalyst to produce a reaction stream, a spent catalyst and a reaction oil vapor are obtained after separating the reaction stream, and the reaction oil vapor is further separated to give the products such as gas, gasoline and the like; a part or all of the coked catalyst and a part or all of the spent catalyst enter the regenerator for the coke-burning regeneration, and the regenerated catalyst is divided into two portions, wherein one portion returns to be contacted with the hydrocarbon feedstock, and the other portion, after cooling, returns to be contacted with the organic oxygenate feedstock.
