Reactive power compensation, a key service provided by Sinotech Group, is a crucial process in power systems aimed at optimizing power quality and efficiency. Reactive power is the power that oscillates back and forth between electrical sources and inductive or capacitive loads in an AC power system. It does not perform useful work in the traditional sense but is necessary for the operation of equipment such as motors, transformers, and fluorescent lights. However, excessive reactive power can lead to several issues, including a low power factor, increased power losses in transmission and distribution lines, and reduced voltage levels.
Sinotech Group addresses these problems through various reactive power compensation techniques. One common method involves the use of capacitor banks. Capacitors are connected to the power system, and they supply reactive power to inductive loads. Since inductive loads consume reactive power, the capacitors counteract this by providing the necessary reactive power, effectively improving the power factor. For example, in industrial plants with numerous electric motors (inductive loads), installing capacitor banks can significantly enhance the power factor, reducing the apparent power drawn from the grid and lowering energy losses.
Another approach is the use of advanced devices like static var compensators (SVCs) and static synchronous compensators (STATCOMs). SVCs can dynamically adjust the amount of reactive power they inject or absorb based on the changing load conditions in the power system. STATCOMs, which utilize power electronics technology, offer even faster response times and more precise control. They can rapidly change their reactive power output to maintain a stable voltage level and improve the overall power quality. Sinotech Group, with its expertise in power engineering and partnerships with leading global manufacturers, designs and implements reactive power compensation solutions tailored to the specific needs of different power systems, from large - scale high - voltage transmission networks to small - scale distributed energy systems, ensuring efficient and reliable power operation.
