Abstract Clustering anonymity is a common social network data privacy protection scheme, which based on graph-clustering. Many existing graph clustering methods mainly focus the relationship between structure and attributes of nodes, difference them due to metric usually causes problem poor results. To address shortcomings in above graph-clustering methods, method implemented with fused distanc...

Abstract We characterize the knowledge production process whereby inventive capabilities of firm generate innovation output in highly multinational enterprises (MNEs). explore sensitivity this relationship to strength intellectual property rights (IPR) protection across MNEs R&D subsidiaries. argue that MNE innovative performance will be enhanced when firm’s activities are based locations w...

The protection of multi-terminal lines is not as simple as that of two-terminal lines. They usually experience additional problems caused by the intermediate infeed from the third terminal, an outfeed, different line lengths to the tee point, etc. The limitations of non-pilot distance relays for their protection have been acknowledged for decades. These limitations lead to the traditional dista...

In this article are presented the basic principles of the numerical protections used for protecting the high-voltage electric lines (110 kV). Is achieved a study for implementing a numerical distance protection DIPA 100, for a high-voltage line (an example from practice). For the numerical relay, is shown the protection characteristic of DIPA 100, characteristics of operation to faults ‘phase-p...

This paper deal with an analytical and simulation of the application of distance relay for the protection of line transmission high voltage 220 kV employing series capacitors compensating devices. A detailed modelling of series compensated (SC) is proposed and integrated in transmission system. The studies also include different challenges which the protection engineer may face such as current ...

Original scientific paper In this paper, the necessity of the protective relay of the micro-grid is described as the anti-islanding protection and Low Voltage Ride Through (LVRT), and the fault characteristics of the renewable energy sources are analysed. The applicability of over-current protection, distance protection, differential protection, pilot protection, voltage protection and frequenc...
