Design and Construction of the Virtual Cloud Platform for the Laboratory
Wang Kefeng,Ye FeiYue 보안공학연구지원센터 2015 International Journal of Smart Home Vol.9 No.11
Construct a virtual cloud platform laboratory, based on the cloud technology. Introduce the design, construction and architecture of the cloud platform in detail. Analyze the advantage and security of the cloud platform. It has low cost of hardware and software, small late maintenance, and centralized data management, the security of data is greatly improved, compared with the traditional computer (PC) laboratory. Meanwhile the virtual platform also has the all characteristics of the real computer. The virtual cloud platform of the laboratory is the trend and direction of the development of the computer lab in the future.

To improve the power quality of a diesel generator set with a pulsed load in a microgrid, this paper studied the operation characteristics of the system and proposed pulsed load conditions for an actual project based on test data. For a low average pulse power and a high peak power, a new mathematical model of the pulsed load in diferent operation modes was proposed. Then, a simulation model of the microgrid was established in MATLAB/Simulink, and the operation of the system was studied considering changes in various pulsed load parameters (the peak power Pk, output duty cycle D and switching period Ts). It was verifed by tests that the simulation model is efective and can refect the operation of the system. Based on the simulation model, the operation characteristics of the system with a bivariate pulsed load were studied, and qualifcation conditions for the diesel generator set in an actual project were proposed.
