Abstract:
Thermal fatigue crack problems of the feedwater nozzle for steam generator have attracted widely attentions, but haven't yet been fully resolved. Depending on the application characteristics of finite element analysis, we developed finite element software ATLAS by directly programming to hardware with OpenGL graphics engine VBO, FBO and GLSL technologies. By fully using of three-dimensional rendering capabilities of the GPU, ATLAS provided a large-scale highly interactive visualization environment for engineers. ATLAS was used to simulate the thermal stress of the feedwater nozzle. A simplified model of the nozzle finite element analysis was created, and the loads and temperature boundary conditions of the nozzle were added on the interior surfaces. The thermal stress curve was obtained after conducting structural thermal stress analysis. We found that ATLAS can accurately import CAD models, mesh, apply a variety of conditions, and complete the numerical simulation of the thermal stress of the nozzle. ATLAS results were consistent with those of ABAQUS calculation, so its accuracy was assured. Finally, we validated the results and draw conclusions.

Abstract:
At present, the gap between China's power grid transmission and distribution business profitability and reasonable return level is still large, which can not meet the normal development needs of power grid enterprises. It is necessary to consider the relationship between the depreciation rate and the rate of return, so that the return of the power transmission and distribution business of the power grid enterprise will gradually reach the reasonable and feasible level. This paper analyzes the influence of the above parameters on transmission and distribution price in qualitative and quantitative aspects, and puts forward some suggestions on how to determine the depreciation rate and return on investment.

Abstract:
Along with the fast development of market economy and the deepening power regulation reform, the competition among the power supply companies becomes fierce. Meanwhile, the mergers and acquisitions become more frequently. To promote the efficiency and the success rate of the merger and acquisition, the technical due diligence may contribute to it. The author fortunately participated in a typical merger and acquisition of a power supply company, as a member of the technical due diligence team. The technical due diligence evaluated the power assets to be taken over, which were divided into eight aspects including power system planning, electric primary, electric secondary, civil, transmission lines, communication and power distribution network. The outcome was acceptable to for both the acquirer and the acquiree, making the acquisition work smoothly. It may also serves as an example for the future mergers and acquisitions in power industry. Therefore, in a merger and acquisition where technical threshold exists such as power industry, a technical due diligence is necessary apart from financial, law, and land property due diligences, which can offer a technical risk assessment and some probable rectification measures to the acquirers.
