How can the firing angle of a twelve phase generator be controlled? 


Best insight from top research papers

The firing angle of a twelve phase generator can be controlled by generating a firing pulse with a phase characteristic waveform . This waveform includes an angular shape waveform added to a circularly curved part of the power source voltage waveform, compared to a firing angle command signal . Additionally, the firing phase angles of the bridge circuits can be exchanged several times to reduce the variation in the load current . Another approach is to control both the governor's angle and the excitation voltage of the magnetic field coil of the generator using a control algorithm based on variable structure control theory . By switching the control parameters according to the position of the system in the phase plane, the dynamic performance of the power generator can be enhanced .

What determines the phase angle in human cells?5 answersThe phase angle in human cells is determined by various factors. One important factor is the interaction between cyclic shear and tensile stresses on endothelial behavior. Another factor is the cellular water status, cell membrane integrity, and cellular mass, which are related to phase angle measurements using bioimpedance analysis (BIA). Additionally, the electrical properties of tissues, including the phase angle, can be influenced by the presence of resistances and variable impedance elements. In the context of cardiac surgery patients, a low phase angle has been associated with malnutrition and adverse postoperative outcomes. Furthermore, in holographic tomography, the rolling angles of cells can be determined based on their 3D positioning while flowing along microfluidic channels.
How can a microgrid be controlled to maintain frequency?5 answersMicrogrids can be controlled to maintain frequency through various methods. One approach is to use controllers such as Proportional-Integral-Derivative (PID) controllers or Fuzzy Tuned - PID (FT-PID) controllers. These controllers can manage the governor of the synchronous power generator (SPG) and the pitch of the wind turbine generator (WTG) to improve frequency stabilization of the system. Optimization algorithms like Salp-Swarm Optimization Algorithm (SSOA) can be used to estimate optimal gains for these controllers. Another method is to implement secondary controllers based on algorithms like the Mayfly algorithm (MA). These controllers can regulate system frequency by balancing the fluctuating values of renewable energy sources (RESs) with energy-storing units (ESUs). Additionally, analytical models and design methods can be used to improve damping for torsional modes and enhance frequency stability. Overall, a combination of control strategies, optimization algorithms, and analytical models can be employed to effectively maintain frequency in microgrids.
How do the ground control points distribute?5 answersGround control points (GCPs) can be distributed in different ways depending on the study area and the available access points. The optimum distribution of GCPs is typically at the edge of the study area, but in some cases, access restrictions may require establishing GCPs in accessible areas. The number and distribution of GCPs can affect the accuracy of photogrammetry products. Studies have found that the best GCP configuration for optimum accuracy is six GCPs with edge distribution. Another study suggests that at least seven naturally occurring ground control points collected in a broad distribution across the site can result in accurate georeferencing. Additionally, a study proposes a method that considers the variance in height of the surface terrain to determine the distribution of GCPs, resulting in greater accuracy than the conventional uniformly distributed method.
