In this study,we introduce our newly developed measurement-fed-perception self-adaption Low-cost UAV Coordinated Carbon Observation Network(LUCCN)prototype.The LUCCN primarily consists of two categories of instruments,including ground-based and UAV-based in-situ measurement.We use the GMP343,a low-cost non-dispersive infrared sensor,in both ground-based and UAV-based instruments.The first integrated measurement campaign took place in Shenzhen,China,4 May 2023.During the campaign,we found that LUCCN’s UAV component presented significant data-collecting advantages over its ground-based counterpart owing to the relatively high altitudes of the point emission sources,which was especially obvious at a gas power plant in Shenzhen.The emission flux was calculated by a crosssectional flux(CSF)method,the results of which differed from the Open-Data Inventory for Anthropogenic Carbon dioxide(ODIAC).The CSF result was slightly larger than others because of the low sampling rate of the whole emission cross section.The LUCCN system will be applied in future carbon monitoring campaigns to increase the spatiotemporal coverage of carbon emission information,especially in scenarios involving the detection of smaller-scale,rapidly varying sources and sinks.

Thermal power Plant with 1 GW Capacity for Meeting Future National Electric Demands

引用

Journal of power and Energy Engineering 2022年第8期10卷 1-11页

作者： Osama A. Marzouk Ahmed A. Arman Marwan M. Al Saadi Ahmed S. Al-Maqbali Sulaiman S. Al Sharji College of Engineering University of Buraimi Al Buraimi Sultanate of Oman

An analysis for a conceptual design of a thermal power plant (with a power capacity of 1 GW) is provided. This power plant can help in meeting the expected increase in the electric demand for Oman’s dominant power system (2.4 GW between 2018 and 2025). A necessary fluid mass flow rate of 834.1 kg/s was predicted. The overall energy conversion efficiency (output useful electricity divided by input heat) was estimated to be 34.7%. The needed thermal energy is not restricted to a specific source, and solar heating is an option for supplying the needed heat. The power plant design is based on using a steam-turbine section, which may be composed of a single large steam turbine having a mechanical power output of 1115 MW;or composed of a group of smaller steam turbines. The analysis is based on applying energy balance equations under certain assumptions (such as neglecting changes in potential energy). The thermal analysis was aided by web-based tool for calculating needed properties of the working medium, which is water, at different stages in the power plant.

变电站接地网系统改造升级过程中,新建接地网对原接地网会产生一定的阻性耦合影响,导致接地系统性能下降,严重威胁电力系统的稳定运行。根据实际工程所提供的数据,基于矩量法以及CDEGS和power station 2种仿真软件对变电站新建接地网与原接地网之间的阻性耦合影响进行研究分析,并根据安全限值标准进一步讨论该变电站接地网系统的优化方案。仿真结果表明,随着新建接地网与原接地网之间水平距离的变化,其阻性耦合的影响也会发生相应的改变,并可通过增设垂直接地体以及网孔数量进一步优化变电站接地网系统,以达到电力系统的稳定运行。

Flight Vehicle Performance and Aerodynamic Control

引用

丛书名： AIAA Education Series

2001年

作者： Frederick O. Smetana

ISBN: (数字)9781600861857

ISBN: (纸本)9781563474637

Flight Vehicle Performance and Aerodynamic Control is designed to serve as a text for either an 11-week or a 16-week course at the sophomore level. It explains typical methods used to estimate aircraft performance, the theoretical basis of these methods, and how various parameters derived from the aircraft geometry can be used to estimate the requirements of control surfaces and the aerodynamic forces required to actuate these surfaces. This book includes time-tested computer programs that perform the analyses in a manner that reduces student error and improves result accuracy. Because the source code is given, users with a FORTRAN compiler can modify the program to suit particular needs. The major advantage of the software is that more realistic problems may be treated and the effects of parametric programs are more accurate than calculators. The programs are available as executables for Windows machines as well as in ASCII source code versions that can be readily compiled and then executed on Unix, Linux, and Macintosh machines, and on mainframes.

＜正＞ Photo-electric conversion efficiency, production cost and stability are critical issues for DSCs to the commercial market. To upscale DSCs size to commercial size, our group was involved in developing a commercial DSCs panel, which could show the industrial way and prospect. The repeatable DSCs module with the size of 150mm×200mm and photo-electric conversion efficiency around 6%, was produced in our laboratory. The first DSCs primary power station with 500 W was installed on our roof for charging the battery.
