In the background of the offshore wind turbine monitoring applications, we analyzed the characteristics of the offshore wind turbine monitor and gave the architecture of the offshore wind turbine monitor system. We designed the system model of blade wear and vibration in offshore wind turbine, and combined with energy efficient data aggregation algorithm based on the specific application to mon...

The assessment of existing infrastructures in the energy sector is great economic importance for world. extension power generation life hydroelectric plants depends on logical decisions regarding maintenance and renewal equipment. For this purpose, a Bayesian network (BN) has been applied to evaluate failures hydraulic turbine calculate failure turbine. Forty-six nodes have identified that will...

A mathematical model and simulation analysis on main control valve mechanism of LNG ship steam turbine are carried out. A reasonable modeling division of main control valve mechanism is achieved in accordance with the idea of modular modeling, and all the models are established respectively. The modeling division includes cam lifting mechanism, oil actuator and double-valve body. The state spac...

Torque measurement is paramount in engine and transmission testing, turbine testing, pump testing and testing of gear trains and power measurement within propulsion systems. Monitoring torque can be critical to the performance of axles, drive trains, gear drives, and electric and hydraulic motors. Other in-plant applications include gas and steam turbines. Really, torque is an important factor ...

Abstract Hydraulic impedance, as an efficient frequency-domain analysis alternative, has been widely utilized in hydraulic transient for decades. Since the mathematical expressions of systems with complicated pipe networks are usually rather complex, it is difficult traditional continuous impedance method to obtain analytical solutions system’s frequency responses directly. Therefore, equivalen...
