Features: The characteristics of photovoltaic grid connection include low active power on the system's incoming side, where even a small amount of reactive power can lead to a very low power factor. Additionally, reactive power fluctuates significantly, requiring compensation equipment to have extremely high response speed and compensation accuracy.
Features: In residential areas, the load imbalance is high, leading to increased transformer noise and higher losses. The compensation equipment is required to accurately compensate for the three-phase unbalanced current.
Features: The spot welding machine is characterized by transient impact load, requiring compensation equipment with extremely high response speed and compensation accuracy. Additionally, the device must have a strong tolerance for impact current.
Features: The characteristic of long cables causing voltage instability is significant voltage drop and phase delay, while the characteristic of compensation management is the need for real-time monitoring and adjustment to address dynamic load changes and various power quality issues.
