Power Grid

Purify the power grid and improve power quality

a.Industry characteristics (Introduction)

   Electric energy is the main driving force of all sectors of the national economy. With the progress of science and technology and the gradual improvement of people's living standards, the types of household appliances are increasing, and the domestic power consumption is increasing day by day. The shortage of electric energy supply or sudden failure will cause huge losses to all departments of the national economy and bring great inconvenience to people's life.

   Due to the existence of a large number of inductance and capacitance elements in the power system (including the equivalent inductance and capacitance of conductors and equipment), there will be a transition process when the operating state changes or fails. Electric energy is transmitted at the speed of light, and the transition process will quickly spread to other parts of the system at that speed. Therefore, the adjustment and switching operation of the normal operation of the equipment and the removal of faults must be completed quickly and accurately by automatic devices.

The voltage or current supplied by the power system is generally a standard sine wave, but it will be distorted in the process of power transmission. There are many reasons for harmonic generation, such as saturation of equipment with iron core, asymmetric operation of the system, access to electronic equipment and rectifier equipment in the system, etc. Nonstandard sine waves must contain high-order harmonics, and the content of high-order harmonics should be very small.

b. Solution

   Our company has products with various functions of power quality problem prevention and control to cooperate with the power grid, which greatly reduces the imbalance of the power grid and plays a vital role in the more efficient operation of the power grid.
