Authors: Chen Dong Yu , Liu Qing Yu
Published: March 2015

To study the influence of KCl pretreating on the pyrolysis kinetics of soybean stalk, the pyrolysis of soybean stalk pretreated by different concentration KCl solutions were performed by nonisothermal thermogravimetric analysis (TGA) at five different heating rates. The Ozawa method was employed to calculate the activation energy. The results showed that the pyrolysis process of the soybean stalk pretreated by 3% and 10% KCl solution can be separated into four stages (water loss, depolymerization and vitrification, thermal decomposition, and carbonization). With the heating rate increasing, the main pyrolysis zone of the TG (thermogravimetric) and DTG curves move to the higher temperature region, and the maximum pyrolysis rate and its corresponding temperature increase too. A small amount of metal salts addition is conducive to the formation of volatile, and a certain amount of metal salts can improve the charcoal yield. More KCl additive makes the lower activation energy value, and the obtained activation energy value increases with the reaction degree.

Published: March 2015

South Korea is implementing policies to save energy and reduce greenhouse gases. As presented in the 4th report of the Intergovernmental Panel on Climate Change (IPCC), buildings have high potential for reducing greenhouse gases, and energy consumption in buildings is actually increasing. Buildings can be classified into the home, commercial, and public sectors. Among these, effects of the greenhouse gas reduction policy for residential buildings, which correspond to the home sector, are difficult to expect because they depend on voluntary participation. An analysis of the related practices showed that the potential greenhouse gas reduction until 2014 is 1,314 tCO2/yr, but the expected greenhouse gas emissions of residential buildings constructed only this year (2014) amount to 37,984 tCO2/yr. Greenhouse gas reduction effects in residential buildings are difficult to expect from current practices. Therefore, practical programs to improve energy efficiency for existing and new buildings are required.

ADRC is made possible only when control is taken as an experimental science, instead of a mathematical one. It is motivated by the ever increasing demands from industry that requires the control technology to move beyond PID, which has dominated the practice.

Published: March 2015

The imbalance in cold and heat load in large public buildings located in a cooling-dominated areas is apparent. To explore the effect of a cumulative cold and heat load ratio (CCHLR) on the performance parameters of the hybrid ground-source heat pump system (HGSHPS) of large public buildings, this study selects a Wuhan office building as the simulation object. When this model is considered as the prototype, five other building models whose CCHLR interval is relatively uniform can be developed. The full-year dynamic loads of the six models were calculated with Designer’s Simulation Toolkits. The 20-year simulation of the six HGSHPS models was conducted with TRNSYS. Then, the performance parameters of the HGSHPS model under different CCHLR values were studied and compared. These parameters included the average soil temperature, exiting fluid temperature (ExFT) of the ground heat exchanger (GHE), average energy efficiency ratio, and specific energy consumption (the electrical energy required to obtain per kilowatt cooling or heating capacity) of the heat pump system. Simulation results indicated that with the increase in CCHLR, the average soil temperature rapidly increases, the ExFT of the GHE increases to a value that is considerably higher than the suggested standard, and the specific energy consumption of the system increases.

Published: March 2015

With chaotic dynamics analysis to the mechanical vibration signals of on-load tap changers(OLTC) operations, a geometric feature extraction scheme is developed for phase portrait structure based on a multi-dimensional coordinate space. The fuzzy set theory is further introduced into OLTC mechanical fault diagnosis, with a view to establishing the normal distribution membership function of every condition fuzzy set. Regarding two sample categories, i.e. single analyte sample and analyte sample sets, both principles of the largest membership and the optional nearly are used for fuzzy reasoning to finally realize mechanical fault diagnosis of OLTC.

Authors: Wei Sheng Xian , Hu Fe Ne , Li Hui
Published: March 2015

The model of the water-mass-to-collector-area ratio (WMCAR) of a flat-plate solar water heating system has been built based on the energy output model of the solar collector. The results show that the calculation values of the WMCAR model are highly consistent with the experimental values and their relative errors do not exceed 10%. The WMCARs of the flat-plate solar collector integrated with large-tilt-angle (70o-90o) into the south façades of the high-rise buildings in five climatic regions including 133 cities in China have been calculated and analyzed. For convenient use in practice, parameter relationships between the values of WMCARs and the main meteorological data have been analyzed by using the linear polynomial regression technique. The regression equations and regression coefficients in summer months and winter months have been given in this paper.

Since the development of economics and society, secured and reliable power supply has become essential. Model and diagrams management remains the fundamental technology for distribution automation and smart distribution system. However, distribution system develops rapidly, simple model and diagrams management and maintenance with GIS would not satisfy the requirements by system operation. In this paper, we propose panorama dispatching technologies as integrative solution for smart distribution system. Firstly, the framework of panorama dispatching technologies is established; then key technologies for panorama dispatching technologies are introduced. With our proposed methods and technologies, the distribution system operators can not only manage and examine accuracy of model and diagram, but also work on a unique strategic diagram to better understand and dispatch the system with multiple levels and views of panorama diagrams.
