可变速抽水蓄能发电技术的应用与进展

 可变速抽水蓄能可成为电网负荷频率控制、平衡可再生能源发电出力波动的有效手段。论文在介绍可变速抽水蓄能整体结构的基础上,重点介绍了交交方式和交直交方式变频励磁单元的拓扑和构成。说明了交交方式具有器件少、可靠性高、易于大容量化等优点,但存在频率只能整数倍减小、无法实现大范围连续调节、响应速度较慢等缺点。而交直交方式具有频率可大范围连续调节、响应速度较快等特点,其性价比呈快速上升趋势。分析了机组在发电方式和电动方式时运行的变速原理和调节过程。通过发电出力与转速的关系曲线说明通过转速控制实现最佳出力的过程。通过泵类负荷输入功率与转速的关系,描述了电动方式下调节转速对电网功率调节的作用。综合考虑能量平衡、波动负荷与可再生能源发电出力跟踪控制及电压稳定控制的需求,形成参考功率。在此基础上,采用d-q解耦方法实现可变速机组有功与无功功率的控制。最后,通过电网功率调节、电压波动控制及风电功率波动抑制示例,阐述了可变速机组对电网运行的控制作用。

Structural and dielectric study of nano-crystalline single phase Sn1−xNixS (xNi=0–10%) showing room temperature ferromagnetism

SnS is a promising Ⅳ-Ⅵ semiconductor,which is very less explored for diluted magnetic semiconducting and dielectric applications.In this study,the Ni doping(x_(Ni)=0-10mol%) effects on SnS host lattice were investigated.A simple and low cost co-precipitation technique was employed to grow Ni doped SnS powders.The X-ray diffraction confirmed single phase orthorhombic structure with a nano-crystalline nature that was further verified through the surface structure observed by scanning electron microscopy.Near edge x-ray absorption fine structure spectroscopy revealed a shift in the Ni absorption edge towards higher energy,depicting the formation of Ni~(+3) oxidation state.The impedance measurements,in the frequency range 1 kHz to 20 MHz,depict that owing to the excellent sensitivity to the electromagnetic radiations at the low energy,the Ni doped SnS finds potential applications in various energy related devices.Vibrating sample magnetometer measurements have elucidated room temperature ferromagnetism,which depicts potential memory device applications.

Evaluating the Impacts of Virtual Organization Absorption on the Quality of Urban Private Constructions; the System Dynamics Approach

Quality compliance checking of urban private constructions in Iran follows a fragmented pattern. By considering this fragmentation along with the inherent complexities of the quality compliance checking, it becomes urgent to look closer at this mechanism to find a way for making improvements. Since there is no determination to change the existing mechanism, this study discusses the use of virtual organizations as a strategy to enhance the level of quality. To this end, according to the intended approach for developing virtual organizations, this study identifies the capabilities of this type of systems in the first step. Then, this research evaluates the impacts of virtual organization absorption on the quality of urban private constructions. In this evaluation, the paper applies the system dynamics approach as the modeling tool due to its ability to address complexities and feedback structures. The resulted dynamic model needs initial values and requires functions to be able to run the simulation. In this case, the Delphi Technique is used to extract the functions and the values. After importing the resulted values and functions into the model, the focus group is used for the validation. The result of this analysis represents the positive impacts of the virtual organization absorption in the quality compliance checking mechanism. Fifty-percent improvement in the quality level of urban private constructions after a twenty-year period is one of the results, which could be considered as an indicator of virtual organization impacts.
