Efficiency Improvement of Permanent Magnet Rotating Electrical Machine (PMREM) with Permanent Magnet Material Selection
Abstract: There are many Permanent Magnet Machines available in the market with the different type of PM material. The rare earth permanent magnet material changes the whole scenario of the market. In comparison with SmCo and AlNiCO magnets, NdFeB magnets have low corrosion resistance. Their chemical reactivity is similar to that of alkaline earth metals like magnesium. Under normal conditions the NdFeB reacts slowly. The reaction is faster at higher temperatures …

Use of single time reference measurements of bus variable in the determination of voltage instability condition of a power system
Abstract: Normal 0 false false false EN-US X-NONE X-NONE The paper describes a measurement based voltage stability index for monitoring of voltage stability condition of a power system. For this purpose, it is required to measure the voltage and reactive power of a target/selected (bus under investigation) along with the voltages of the other buses connected to the target/selected bus for a single time instant. These measurements and transmission line parameters …

Integrated Maximum Power Point Tracking and Harmonic Reduction in a Grid Interactive Solar PV Inverter
Abstract: Normal 0 false false false EN-US X-NONE X-NONE A solar photovoltaic (PV) cell exhibits a non-linear i-v characteristic and its maximum power point (MPP) varies with solar insolation and temperature. A dc-to-dc converter is generally employed along with inverter circuit to operate the solar PV system at maximum power point. This adds to the cost, which increases significantly with the size of the system. Moreover, grid-tie inverter employing thyristors has …
