The new standard C37.118.1 lays down strict performance limits for phasor measurement units (PMUs) under steady-state and dynamic conditions. Reference algorithms are also presented for the P (performance) and M (measurement) class PMUs. In this paper, the performance of these algorithms is analysed during some key signal scenarios, particularly those of off-nominal frequency, frequency ramps, ...

Deductive databases are paraconsistent theory systems which change over time. They do not support the inference of arbitrary consequences from inconsistent components, such as contradictory definitions of database relations (predicates) or violated integrity constraints. Moreover, computed answers in deductive databases typically make sense, almost no matter to which degree consistency or integ...

In this paper HVDC is investigated for its ability to supply a passive industrial system. The objective of the paper is to assess the potential and limitation of the use of dc distribution in the industrial power system. The performance of the dc supplied distribution system is compared with pure ac supplied distribution system of simi lar ratings under balanced faults on the grid side and moto...
