Within the context of industry 4.0, the personalized customization requires the manufacture more agile and flexible, which means the reconfigurable manufacturing system is crucial for enterprise to remain competitive. However, most of the existing systems have to suspend when reconfiguring, as the online reconfiguration may lead system to disorder and uncertainty. To minimize the leading time of reconfiguration...
Industrial Cyber-Physical Systems enhance physical devices with control, computing and communication abilities to provide smart solutions for industrial applications. In industrial applications, data acquisition is an important topic. Based on feedback data from sensors and equipment, industrial processes could be optimized either by experienced engineers manually or smart agents automatically. The...
The current requirements for personalized customization drive the manufacturing industry to make adjustments constantly, which means a longitudinal unobstructed and transverse reconfigurable system is crucial for enterprise to remain competitive. However, the leading time for launching a new system or reconfiguring an exist system is cost-intensive and time-consuming. This paper proposed a new structure...
With rapid improvement in information and communication technologies, industrial automation systems are under the revolution. Legacy industrial automation systems lack flexibility and interoperability due to multi-layered architecture. From industrial cyber-physical system point of view, a new system architecture is needed to allow vertical and horizontal integration between all devices and systems...
In this paper, an adaptive integrated hybrid AC/DC microgrid module is proposed to accommodate a wide range of Distributed Renewable Energy Resources (DRERs), Distributed Energy Storage Devices (DESDs) and Distributed Demand Resources (DDRs) into the existing distribution systems. The concept and the architecture of adaptive integrated hybrid AC/DC microgrid module have been elaborately explained...
Repetitive wave voltages should be used to perform partial discharge inception voltage (PDIV) tests on insulation systems of type I rotating machines fed by power electronics in qualification and type tests according to new standards published by International Electrotechnical Commission (IEC). To obtain objective test results, the influence of waveform parameters on PDIV results should be carefully...
The repetitive impulsive surges from inverters has been found undoubtedly to cause insulation reliability flaws in inverter-fed motors. To mitigate this problem, PD detection and life testing under sinusoidal and/or repetitive square voltages should be performed on new types of inverter-fed motor insulation, according to IEC standard and Technical specification(TS), (i.e. IEC 60034-18-41 and IEC TS...
High-voltage power metering systems based on electronic instrument transformers (EITs) have some advantages compared to the conventional ones. This paper describes an unique calibration method and device for the power metering system. High accuracy with the calibration method can be achieved. The estimated relative uncertainty of the device is about 200×10−6 in magnitude and less than 110 µrad in...
With the breakthrough of electrooptical technology research on sensor application, the promulgation of IEC 61850, the application of Ethernet communication technology and the development of intelligent breaker, digital substation has become the mainstream of substation automation technology development in future. This paper briefly discusses issues related to electric energy measurement in digital...
