when an output overcurrent of an inverter 4 is detected and goes to an overcurrent exceeding a set value, and a means for detecting a phase difference to an output voltage of an output current of the inverter 4, selecting two signals in accordance with lead and lag, and inputting them ...
Power factor 0.94 lag 0.96 lag 0.984 lag 1 0.98 lead 0.92 lead 0.879 lead Thus, the d-axis rotor reference current is determined by reactive power controller, as shown in Fig. 5. αd in Fig. 5 is the bandwidth of the d-axis rotor current control loop. Using the PI controller as KQ...

1. Intelligent controller control, complete functions. Reliable performance, automatic compensation; The power factor can be increased to more than 0.9; 2. Real-time display of power factor and display range; Lag (0.00-0.99), lead (0.00-0.99) ...
This usually leads to a chronological sequence of activities that may lead to inefficiencies because active and reactive powers are coupled given the capability diagram of synchronous generators, the ac power flow equations and the branch thermal limits. In this paper, we propose new models to re...
Therefore, we anticipate the triboelectric materials and their derived CEC could lead to a field of ball milling-assisted mechanochemistry using universally available triboelectric materials. Here, exemplified by a typical liquid-assisted grinding (LAG) process, we demonstrate that the presence of ...
In the previous chapter, you learned about the real workhorses behind reactive programming with RxSwift: the map and flatMap dynamic duo. Of course, those aren’t the only two operators you can use to transform observables, but a program can rarely do without using those two at ...
Comparing the results of the three systems, it can be seen that the addition of 10% organics in the synthesis lead to a decrease in the hydrodynamic size of the final particles for the EDTA system and an increase in the hydrodynamic size of the particles for the EDDS system, partially ...
Even without increases in N applications to watersheds, hydrologic alterations that route rainfall efficiently into receiving streams lead to predictable increases in storm-borne delivery of N to surface water ecosystems (e.g., Shields et al. 2008; Davidson et al. 2010). Collectively, enhanced N...
which serves the dual purpose of being the second igniter lead and a conveyor of flammable gas. Various materials with desired physical and/or thermal properties may be used for these burner components. The spark may jump between the igniter lead and the tube where the flammable gas first mixes...
