Sentence examples for mechanical power variation from inspiring English sources

The optimal mechanical power variation with k h is plotted in Fig. 9b.

The robustness with respect to 3 phase short-circuit and mechanical power variation constitutes the main positive features of the proposed approach.

It can be concluded that the main factors causing the generator frequency variation are the work done by the mechanical power variation, the work of load power variation supplied by the generators, and the work of transmission power loss variation undertaken by the generators.

The mechanical power variation ΔP mi, which is compared to its value at steady state, is given as varDelta {P}_{mathrm{m} i}={P}_{mathrm{m} i}-{P}_{mathrm{m} i}^{mathrm{S}}Rightarrow {P}_{mathrm{m} i}=varDelta {P}_{mathrm{m} i}+{P}_{mathrm{m} i}^{mathrm{S}} (11).

The simulation outcomes show that the proposed control scheme allows achieving prompt mechanical power variations.

In recent years, wind energy has become an important part of the electrical power generation, however, the wind variations produce mechanical power fluctuations and, consequently, the speed changes in the turbine rotor lead to variations in the currents and voltages produced by the wind generators.

In addition, measured values of the average torque, mechanical power, volumetric flow rate and transient pressure variations in the suction and compression chambers are shown to be in good agreement with theoretical predictions.

Before the influence of divergent factors on gross efficiency (GE) [the ratio of mechanical power output (PO) to metabolic power input (PI)] can be assessed, the variation in GE between days, i.e. the test retest reliability, and the within day variation needs to be known.

Due to the WG inertia, while the mechanical torque oscillates with an amplitude equal to 50%% of its average speed, active power variation is restricted to 25%% of its average power.

For the same heat flow rate on the heat exchanger (the same temperature variation of the solar water and the same mass flow rate), both mechanical power and thermal efficiency increase.

Mechanization refers to the replacement of human (or animal) power with mechanical power of some form.
