Out-of-phase synchronization (OPS) fault may occur to the turbine generator used in gas-steam combined cycle units, which seriously endanger operation stability of unit. To investigate influences rotor structure on field current and electromagnetic a under OPS, 2-D field-circuit-grid coupled model (FCGCM) 150-MW is established. By using established FCGCM, slot indexing number (RSIN) magnetic permeability wedge OPS 180° were studied. A no uniform coefficient (MNC) was proposed evaluate...
印支地块是东亚大陆主要陆块之一，其主体位于东南亚地区。过去的研究认为其可能来源于古生代的冈瓦纳大陆，伴随着晚古生代以来的特提斯洋演化过程，印支地块逐渐从南半球冈瓦纳大陆裂离，向北半球漂移并汇聚拼贴到东亚大陆上来。随着近几年的古地磁学工作的进展，获得了丰富的定量半定量数据，印支地块晚古生代以来的运动过程才得到了较为精确的重建。本文通过详细总结和深入分析前人发表的和我们最新从印支地块获得的古地磁数据，系统地刻画了晚古生代以来印支地块从南半球向北半球的漂移运动过程。晚古生代印支地块位于南半球中低纬度地区，在二叠纪末期跨越赤道，到了晚三叠世运动到北半球30°N附近，很可能此时已经拼贴到欧亚大陆主体上来，中生代之后又经历了一系列的构造调整。基于古地磁数据的运动学重建，使得古特提斯构造域主要块体的构造关系和相对运动历史也得到了进一步的厘定，从运动学的角度证明了北羌塘地块和印支地块具有明确的古地理亲缘关系，同时，两者与滇缅泰地块和南羌塘地块的运动过程具有明显的区别。结合东亚诸关键陆块的最新古地磁学研究进展，细致重建了东亚陆块群对Pangea超大陆汇聚过程的独特响应。
Unmanned aerial vehicles (UAVs) have been envisioned as essential technology to enhance the service quality of wireless systems, whereas security issue is unavoidable. In this paper, a reconfigurable intelligent surfaces (RIS)-aided air-to-ground secure communication paradigm conceived, where RIS used boost confidential signals from UAVs ground users. However, robust trajectory and beamforming designs are required fully reap enhancement capabilities for UAV links under imperfect channel...
To research the influence of rotor structure on field current and electromagnetic a turbine generator under Out-of-Phase Synchronization(OPS), an 2-D Field-Circuit-Grid Coupled Model (FCGCCM) 150MW is established. By using established FCGCCM, oscillation ratio (FCOR) OPS 180° was studied, when slot indexing number changed magnetic wedge used common slots. A nonuniform coefficient (MNC) proposed to evaluate nonuniformity rotor. The relations MNC were investigated.
In the Internet era, personal freedom of speech has been fully reflected, but it also brought a lot negative effects."Internet witch hunting" refers to human flesh search, information collection, attacks on specific people Internet, and stirring people's emotions through Internet. recent years, with development rumors online violence other phenomena began spread On social media platforms, great hidden dangers public security. With technology, privacy paid more attention. How protect prevent...
<title>Abstract</title> The time-sensitive networking (TSN) technique has shown its potential to provide deterministic communication guarantees for industrial applications. Specifically, the recently applied cyclic queuing and forwarding (CQF) mechanism in TSN can further bounded latency stable delay jitter time-triggered (TT) flows with simplified configuration of gate control list (GCL) switches. However, previous traffic scheduling approaches CQF have overlooked influence routing...
A significant problem of turbogenerators on complex end structures is overheating local parts caused by losses in the region. Therefore, it important to investigate 3-D magnetic field and eddy current loss end. In region operating large turbogenerator at thermal power plants, leakage distribution complex. this paper, a mathematical model used for calculation electromagnetic turbo-generators given. The influence spatial locations structures, actual shape material windings, clamping plate,...
The renewable energy grid-connection has a negative influence on the transient stability of power grid for lack voltage support and damping control capability. This paper aims to study functions novel MGP system improving with its advantages synchronous machines. First all, structure motion equation grid-connected via is given. Then mechanism analyzed through phase diagram two It turns out that output reactive generator can respond disturbance spontaneously. Afterwards, function excitation...
The working performance of an electric machinery can be improved by adopting magnetic slot wedge on the stator or rotor. To investigate influence field distribution and saturation reactance a turbo-generator, 2-D mathematical model for electromagnetic 150MW air-cooled turbo-generator has been established considering two different types rotor slots. It is put forward that using weakly Cr-Ni alloy high-strength Fe-Cu to replace common A1 improve static stability generator.
