Because most of the photovoltaic power stations are built in the high altitude and remote areas of Tibet, the special climate conditions make the traditional operation and maintenance mode not suitable for the rapid development of photovoltaic power generation industry. Based on the operation and maintenance status of photovoltaic power station equipment, this paper analyzes the difficulties faced by the operation and maintenance of photovoltaic power station in Tibet under the current situation, and deeply explores the innovative design scheme and key measures to realize the functional design of the operation and maintenance platform of photovoltaic power station.展开更多

In this paper, the current research on offshore structure removal and jacket cutting is introduced, on the basis of which the types of load along with the load calculation method are determined. The main influences on the stability of a jacket in cutting are analyzed. The experiment test plan is drawn by using orthogonal testing method, and the formula of critical load during the cutting procedure is deduced by differential evolution algorithm. To verify the method and results of this paper, an offshore piled platform to be decommissioned in the South China Sea is taken for an example, and the detailed schedule for jacket cutting is made with the three-dimensional finite element model of the jacket established. The natural frequency, stress, strain and stability of the jacket during cutting process are calculated, which indicates that the results of finite element analysis agree well with that of the deduced formula. The result provides the scientific reference for guaranteeing the safety of jacket in cutting operation.展开更多
