Research and application of the system of electric power engineering in the Huangling Mining 2 × 300MW power plant construction period
A lot of things that need to be managed in the thermal power projects. In this process, many factors are constrained and associated each other, That all aspects of works are plan organize, coordinate, control and management Legitimately are the guarantee of success.In the process of building the Huangling Mining 2 × 300MW power plant, through the use of the electricity project management system, preparation office, supervision, design, construction, and other units gather into a platform. The major event, the document marking, project, contract management, material supply, acceptance settlement integrate information platform. Preparatory Office can control of the project's funding, schedule, quality, safety In every moment. It can easily coordinated, Controled, and managed works.
Study on the Plan and Control Method of Construction Project Progress and Cost Integration
Based on the principle of system integration,this paper analyzes the correlation of progress and cost in the construction process,and the plan and control method of integrating the progress and cost of construction projects,and provides the precondition of applying into the construction practice.The research result can directly guide the construction management practice and also work as the base of the developing the compute aid decision system of construction project cost and progress integration management.
Frequency distributions of the mixing height over an urban area from SODAR data
The height of the mixing-layer (MLH) is an important parameter in the assessment of the dilution of primarily emitted or secondarily formed air pollutants in the atmospheric boundary-layer. A continuous measurement of MLH is possible only by remote sensing. Here, 17 months of SODAR data have been analysed automatically to derive the MLH over the city of Hannover in Northern Germany. In contrast to earlier studies the MLH has been determined from vertical profiles of the acoustic backscatter intensity and from the variance of the vertical velocity component. The results are presented in form of monthly frequency distributions and mean daily courses of MLH. These statistical evaluations of MLH show a clear annual course and interannual variability. The study shows the possibility to derive meaningful climatological information from long-term SODAR measurements for air quality issues.
