Sentence examples for under unbalanced loads from inspiring English sources

This paper aims to realize the balance control of three-phase grid currents under unbalanced loads.

In [7], the grid currents are controlled as balanced sinusoidal currents in the positive and negative sequence double synchronous rotating coordinates under unbalanced loads.

However, the DC bus voltage will produce a larger fluctuation under unbalanced loads, and this may cause the current reference to be distorted and thus the sine and balance degrees of the grid currents to be poor.

To overcome the influence of unbalanced loads on the grid side neutral potential shift, it is necessary to control the three-phase grid currents to keep them in a sinusoidal and balanced state under unbalanced loads.

To overcome this issue, the neutral-grounding method can be employed, but when it operates under unbalanced load conditions, the neutral current flowing through the grounding winding may cause overheating and failures.

The parallel converter will output a zero sequence current iLN under the unbalanced loads: i_{text{para}} + i_{text{parb}} + i_{text{parc}} = i_{text{LN}} (34).

In this case, the latter has to form the grid, regulating voltage and frequency, what can be very challenging under highly unbalanced loads and single-phase RESs.

The proposed system has maintained fixed terminal voltage at 220 V, voltage and current harmonics within 5% under highly nonlinear load and balanced source currents under highly unbalanced load currents.

It is found that the SPC is suitable for dealing with a full range of unbalanced loads under the condition where the input-stage current stress increases.

To evaluate the role of the transverse beam in the redistribution of unbalanced loads under the column removal scenario, a separate analytical model of the transverse beam that simulates cantilever behavior was constructed and analyzed under free end loading.

If the circumferential wave numbern= 1, the vibration response of the drum keeps a stable value under an unbalanced load of the disk, there is no coupling effect if n≠1.
