Reactive power compensation device is a commonly used equipment in power system, which is used to compensate the reactive power in the system, improve the power factor of the system, improve the utilization rate of electric energy, and ensure the normal operation of power equipment. This paper will discuss the role of reactive power compensation device and its importance in power system.

1. Improve the power factor

the reactive power compensation device compensates the reactive power in the system, so that the power factor of the system is close to 1, and the power factor of the power system is improved. High power factor can reduce the invalid power loss in the system, improve the utilization rate of electric energy and reduce the cost of electric energy.

2. Reduce power loss

in the case of low power factor, there will be a large invalid power loss in the system, resulting in waste of electrical energy. The reactive power compensation device compensates for reactive power, which can reduce the loss in the system, save energy resources, and reduce production costs.

3. Improve system stability

low power factor will cause frequent voltage fluctuations, affect the normal operation of power equipment, and even cause equipment damage. Through the reactive power compensation device to improve the power factor, can stabilize the system voltage, to ensure the safe and stable operation of power equipment.

4. Reduce grid voltage loss

low power factor will lead to an increase in grid voltage loss and affect the stable operation of the grid. The reactive power compensation device can improve the power factor of the power grid, reduce the voltage loss of the power grid, and improve the load capacity and stability of the power grid.

5. Improve the efficiency of power equipment

in the case of low power factor, the efficiency of power equipment will be affected, the work efficiency will be reduced, and the energy consumption will increase. Improving the power factor through reactive power compensation devices can improve the operating efficiency of power equipment, extend equipment life, and reduce maintenance costs.

6. Reduce system failure rate

low power factor will cause the current in the system to increase, equipment overload operation, easy to cause equipment failure. By reactive power compensation device improving the power factor can reduce the current in the system, reduce the equipment load, reduce the system failure rate, and improve the system reliability.

Reactive power compensation device plays an important role in the power system, its role is not only to improve the power factor, reduce power loss, but also to improve system stability, reduce grid voltage loss, improve the efficiency of power equipment, reduce system failure rate. In the design and operation of power system, the rational allocation of reactive power compensation devices is of great significance for improving the operating efficiency of the system, reducing costs and ensuring the safety of equipment.
