In modern power systems, reactive power is an important concept that cannot be ignored. Unlike active power, reactive power is not directly converted into mechanical energy, thermal energy, or other forms of energy, but it is crucial for the stable operation of the power system and the guarantee of electrical energy quality.High and low voltage passive reactive power compensation complete set device

The existence of reactive power mainly stems from the phase difference between the current and voltage of various inductive and capacitive loads in the power grid. This phase difference can cause energy in the power grid to flow back and forth between the power source and the load, resulting in unnecessary energy loss and a decrease in grid efficiency. In order to solve this problem, reactive power compensation technology has emerged.

The basic principle of reactive power compensation is to install reactive power compensation devices such as capacitors, reactors, etc. at appropriate positions in the power grid to provide or absorb reactive power, thereby adjusting the distribution of reactive power flow in the power grid. This can not only reduce the flow of reactive power in the power grid, reduce line losses, but also improve the power factor of the power grid, enhance its stability and reliability.

With the rapid development of power electronics technology, reactive power compensation technology has also been continuously innovated and improved. Modern reactive power compensation devices have been able to achieve dynamic, continuous, and accurate reactive power compensation, effectively responding to various complex changes in the power grid. At the same time, the application scope of reactive power compensation technology is constantly expanding, from traditional power systems to new energy fields such as wind power and photovoltaics, providing strong support for the efficient utilization and grid connected operation of new energy.

In short, reactive power compensation technology is an important means to improve the efficiency of the power system and ensure the quality of electricity, which is of great significance for promoting the sustainable development of the power industry.
