Sensor technology is a core of electromechanical automation system. Among them, sensor is also the most important content of high-tech electronic technology in China, but the application level of sensor technology in China is relatively backward. Although sensor technology is constantly updated and strengthened, there are still some problems in the application of sensor technology. In this paper, the problem of easy being interfered and high energy consumption has been explained, and some corresponding solutions have been discussed.

Frontiers of Mechatronical Engineering, Vol.2, No.3, 2020; 318 Views, 6 PDF Downloads

With the rapid development of the social economy and the continuous extension of Internet technology, China’s power grid has entered the ranks of large-scale, high-voltage, and intelligent. The main purpose of the fault location of the transmission line is to eliminate hidden trouble and restore the fault line in time to ensure the safe and stable operation of the power system. With the advent of the smart grid, higher requirements are put forward for fault location accuracy, while the traditional wavelet transform and Hilbert-Huang transform have larger defects. Therefore, this paper extensively analyses the generation and characteristics of fault traveling waves in transmission line fault, which proves that the traveling wave location method has higher location accuracy than the fault analysis method. Among them, the two-terminal traveling wave positioning method only uses the arrival time of the initial traveling wave, avoiding the principled defects and locating the dead zone of the single-terminal traveling wave positioning method, so the two-terminal traveling wave positioning method is generally used. The key of the two-terminal traveling wave location method is that it can accurately detect the arrival time of the initial traveling wave head. Although the Hilbert-Huang Transform (HHT) method can be used to detect the arrival time of the initial traveling wave head, the problem of inaccurate detection or failure of the wave head may arise when the instantaneous frequency of the IMF component decomposed by the Hilbert-Huang transform is used because of the mode aliasing in the empirical mode decomposition algorithm. Based on the above analysis, an empirical mode decomposition (EMD) combined with the Teager energy operator(TEO) is proposed for the traveling wave fault location of transmission lines. A large number of simulations prove that the EMD-TEO method in this paper can solve the problem of inaccuracy or failure of the HHT method using instantaneous frequency to detect the arrival time of wave head, and has higher fault location accuracy.

Hydrogen Round Trip Efficiency

by Chao Zheng

Frontiers of Mechatronical Engineering, Vol.2, No.3, 2020; 376 Views, 21 PDF Downloads

The hydrogen economy is a glimpse into the future economic structure of energy. Hydrogen can be used as a power medium, and a typical way of using hydrogen is the round trip, defined as a process in which electricity becomes hydrogen and then returns to electricity form. The purpose of this paper is to briefly describe hydrogen round trip efficiency from production to releasing and find out the optimistic circumstances.

Research on Construction Technology and Quality Control of Electromechanical Installation Engineering for Buildings

by Wending Zhang

Frontiers of Mechatronical Engineering, Vol.2, No.3, 2020; 358 Views, 18 PDF Downloads

Mechanical and electrical installation is a very important construction technology in construction engineering. From the perspective of the construction unit, whether the installation technology and procedure are scientific and reasonable will have a direct impact on the final quality of the project, and it is also closely related to the personal and property safety of the residents. Based on this, construction organizers should construct and perfect a standardized installation construction quality management system, clarify management regulations, and control key technical points, so as to comprehensively improve the quality of electromechanical installation projects and improve the project qualification rate. This article will describe the construction technology and quality control strategy of electromechanical installation engineering, aiming to lay a theoretical foundation for the improvement of engineering qualification rate and construction quality.
