The Village

The Village of Hope is an orphan community located in rural Zambia. The community is made up of several buildings of a variety of uses and schedules. They are currently tied to the grid, which is unreliable due to rolling blackouts for 2 to 4 hours per day. The community is looking for a financially beneficial solution to their electrical needs. A system optimization and sensitivity analysis was performed to determine system recommendations for the community. It was found that wind turbine systems supplementing a grid connection is the most realistic solution for the Village of Hope. However, there were many other factors identified that require further analysis to be able to truly optimize the system.

System Power

The Distributed Generation can enhance the system power supply reliability and alleviate the pitch peak and restricted transmission capacity caused by large-scale wind power grid connection and other problems. In Fuxin, the system power supply is inadequate; the wind power integration is restricted and there are rich wind power reserves. Based on the current situation, this paper analyzes the necessity and feasibility of developing the distributed wind power in Fuxin and provides advisory opinions on the development sites and mode of wind power generation.

Once freeways are classified as arterial systems, they are directly associated to accessibility which has implications on efficiency of a road network design. The geometric design standards influence the freeways’ conception and operation and, therefore, they certainly have an impact on accessibility and the country’s development.A comparative analysis of geometric design of freeways was focused on two policies, both from Portugal and United States of America. The data gathered the geometric parameters regarding the design controls, criteria, elements of design and cross section elements.The major finding of this review infers that the Portuguese Policy imply wider and extensive freeways that arise from strong restraints in the minimum values of geometric parameters. This reflects on higher safety frame. The American Policy is less conservative which may reflect on slender geometric freeways, in comparison with the Portuguese. Therefore, it may be assumed that the American Policy designs less expensive freeways.

Dike roads include water conservancy projects and highways or public works, so the industry cross exists in designs. During the process of dike road designs, there exists problems such as disjointed dike designs and road designs, the lack of adaptation classification system and design standards, inconsistent requirements of embankment compaction and subgrade compaction, the lack of a connection with the inner road network design and green landscape design and other issues. We should fully consider the differences between dike design and road design, according to the particularity of the road dike, and we have proposed several proposals, such as increasing related indicators in the early design of the dike road design, establishing the dike road classification system, uniforming embankments and subgrade compaction standards, strengthening connections with the surrounding road network design and paying attention to greening landscape designs.
