Microseismic monitoring of Well J-253 in complicated construction

Zhao Xinhong,Che Hang,Luo Jiong

Strategic Study of CAE 2012, Volume 14, Issue 4,   Pages 12-15

Abstract:

Well J-253 is located in the J-11 fault block of North China oil field. The direction and geometry size of hydraulic fracture are affected by the stress, geological structure and faults, as well as hydraulic sand blasting. The direction of the initial artifical fracture is at NNE, deviating from the direction of the maximum herizontal principal stress. Then it turns to the direction of the maximum horizontal principal stress and normal direction of contour. Moreover, there are significant fissures lined around the well. It has typical significance to study the artifical fracture direction and geometry of Well J-253.

Power maximization of variable-speed variable-pitch wind turbines using passive adaptive neural fault

Hamed HABIBI, Hamed RAHIMI NOHOOJI, Ian HOWARD

Frontiers of Mechanical Engineering 2017, Volume 12, Issue 3,   Pages 377-388 doi: 10.1007/s11465-017-0431-4

Abstract:

Power maximization has always been a practical consideration in wind turbines. The question of how to address optimal power capture, especially when the system dynamics are nonlinear and the actuators are subject to unknown faults, is significant. This paper studies the control methodology for variable-speed variable-pitch wind turbines including the effects of uncertain nonlinear dynamics, system fault uncertainties, and unknown external disturbances. The nonlinear model of the wind turbine is presented, and the problem of maximizing extracted energy is formulated by designing the optimal desired states. With the known system, a model-based nonlinear controller is designed; then, to handle uncertainties, the unknown nonlinearities of the wind turbine are estimated by utilizing radial basis function neural networks. The adaptive neural fault tolerant control is designed passively to be robust on model uncertainties, disturbances including wind speed and model noises, and completely unknown actuator faults including generator torque and pitch actuator torque. The Lyapunov direct method is employed to prove that the closed-loop system is uniformly bounded. Simulation studies are performed to verify the effectiveness of the proposed method.
