Voltage and Reactive Power Optimization of Main Electric Power Network in Chongqing

Based on the reactive surplus of Chongqing 220 kV main electric power network under low water and low load, and on state of higher system voltage, a thorough research is done on voltage and reactive power of the system power network by means of calculation,analysis and experiments. A main network calculating equivalence model of power network in Chongqing is constructed. And reactive power optimizing calculation is figured out on the Chongqing power network on condition that the loss minimum of the active power network is object function. Several optimizing compensatory schemes are put forward. Based on the calculation result and the analysis of all schemes, the most reasonable and feasible optimizing scheme could be achieved. Meanwhile, the feasibility that the system voltage could be adjusted when generator operating under excitation was demonstrated. According to the experience of under-excitation operation of the same type units , it decreases the system voltage, improves Chongqing power network running performance, and strengthens the coordination and stabilization of system.

Simple Analysis of the Thermal Environment in Chongqing

There are a series of city environmental problems especially in the mountain city along with the city fast development. In recent decade, many scholars have studied the urban heat island, the urban temperature, the urban wind field, the precipitation and the urban visibility etc. But the urban thermal environment has not been settled radically. All the measures have not been used in the practice. And the researches in thermal environment of the mountain cities are very few. So the authors consider Chongqing as the researching object. Chongqing is one of the typical mountain cities in the semi-tropical. Sequentially we find out the characteristic of the thermal environment in the mountain city. Further the authors seek for the measures to plan and build ecological city. They conclude that CFD can be used in the simulation of urban environment, and use the result of simulation in urban planning is possible. The thermal environment in the center of Chongqing needs to be improved.

Dynamic Analysis and Forecast of Ecological Footprint in Chongqing during the Initial Ten Years Directly under Central Government Administration

Based on statistical data for Chongqing Municipality,P.R.China,and using ecological footprint theory,a dynamic calculation was carried out to determine the ecological footprint of Chongqing during the initial ten years that the area was under direct central government administration.The result indicates the following: the per capita ecological footprint in Chongqing increased gradually from 1.3767 49 hm2 in 1997 to 2.113 609 hm2 in 2006;the ecological capacity per capita decreased from 0.438 07 hm2 to 0.406 153 hm2;and the ecological deficit increased from 0.938 671 hm2 to 1.707 456 hm2.By 2010,it is forecasted that: the ecological footprint per capita will be 2.956 hm2;the ecological capacity per capita will be 0.385 1 hm2;and the ecological deficit will be 2.570 9 hm2.All these indicate that Chongqing is entirely in an ecological deficit state with the deficit increasing annually.The development mode of the city is an unsustainable one.In this paper,we summarize the calculated result,point out the reasons for ecological deficits in Chongqing,and conclude with some instructive advice for referral to the Chongqing government.

Rural Revitalization Based on Smart Contraction Concept: A Case Study of Planning and Construction of Dawan Yard,Tianwan Village,Wanzhou District,Chongqing City

This paper introduces the concept of "smart contraction" and its enlightenment to the revitalization of rural areas. Taking Dawan Yard in Tianwan Village, Wanzhou District, Chongqing City as an example, construction dilemmas in mountain area are analyzed, such as backward rural economy, low farmers' incomes, the loss of labor population, the decentralization of village construction land, small-scale village construction land, and the lack of technology and funds for the improvement of village living environment. Combining with the development opportunity of Dawan Yard in Tianwan Village, it puts forward three planning countermeasures of "smart contraction": smart utilization of village resources, smart allocation of public service facilities and smart inheritance of village memory. We hope to provide a new way to revitalize the countryside via case analysis of Dawan Yard.

Potential for the Adaptation and the Strategic Implementation of Local and PRC Resources for Industrialised Housing in Chongqing

The provision of quality industrialized housing in Chongqing to meet demand is perceived by the Chongqing Construction Commission to be a key feature of the local construction industry's future development. The growing strategic importance of Chongqing as a developing municipality, at the junction of the Yangtze and Jialing rivers, will ensure continuing economic development in the region. To facilitate such development the local construction industry will need to react accordingly to provide new infrastructure, commercial development, and housing and recreation facilities. Clearly, this must be achieved in accordance with a robust Master Plan, which addresses all issues associated with the built environment and other environmental considerations relating to pollution, conservation and sustainability. Throughout the World it is becoming increasingly recognized that traditional forms of construction are not sustainable in the long term and that new concepts and methods of construction must be developed. Construction must more effectively utilize and re-cycle resources that would otherwise become depleted or exhausted. Further, all aspects of the in-use performance of buildings, especially housing, must be significantly improved. The situation in Chongqing is no exception to this perception and hence the purpose of this paper is to evaluate locally available resources and relevant resources elsewhere in China to assess the potential for adaptation for effective use in industrialized housing. A broad approach will be taken covering all forms of human and non-human resources, especially those resources which can be re-cycled rather than being consigned to waste. By-products from other industries will be considered, such as those from agriculture and manufacturing. A key aspect of this paper is the articulation of a framework to facilitate the realization and development of an industrialized housing system by the creation of an integrated supply chain capable of delivering the necessary design and performance features geared to affordability, conservation and sustainability. The paper will be concludes by presentation of recommendations regarding the introduction of a development strategy geared to an incremental timetable for implementation.
