THREE-PHASE ASYNCHRONOUS MOTORS

Large quantities of oil usually remain in oil reservoirs after conventional water floods. A significant part of this remaining oil can still be economically recovered by Water AlternatingGas (WAG) injection. WAG injection involves drainage and imbibition processes taking place sequentially, hence th[r]

1) DM: The basic scheme, the DM current controller (DM-CC) [74], [82], is shown in Fig. 9(a). It looks quite similar tothat of a hysteresis CC [Fig. 6(a)], but the operating principleis quite different. In fact, only the error sign is detected bythe comparators, the outputs of which are sampled at a[r]

The simulation of power transformer models is
important when analyzing the dynamic behavior of power
systems, in particular, when considering voltage magnitude or
phase regulation controls. This paper reports results of
extending the library of transformers in the iTesla Modelica

All orbitals are computed using the hydrogenic equations, but any atom can be specified by givingthe number of protons (sometimes referred to as Z), and the atomic weight. A reasonableapproximation of atomic weight is (Z+N) amu, where N is the number of neutrons, and an amu(atomic mass unit) is 1.66[r]
