Overview
The current status of power quality in power grids with developed industrial loads, where daily electricity consumption is huge and the load is non-linear and impulsive, has caused various problems in power quality, mainly including low power factor, high harmonic content, three-phase imbalance, power impact, voltage flicker, and voltage fluctuation.

The specific hazards of power quality issues are as follows

1. The power factor of the power grid is low, which increases grid losses, increases production costs, and reduces production efficiency,

2. The frequent start-up of transmission equipment has caused reactive power impacts, causing voltage drops, voltage fluctuations, and voltage flickers in the power grid. In severe cases, it can cause the transmission and protection devices to malfunction and even affect production,

3. Due to the use of power electronic devices such as frequency converters, high harmonic currents are generated, resulting in time-varying voltage and current in the power grid,

The Role of CY SVG in the Application of Power Transmission

1. Stabilize weak system voltage and improve power quality;

2. Reduce transmission loss;

3. Buffered power oscillation;

4. Increase damping for small disturbances first;

5. Enhance voltage control and stability, improve the reliability of weak connection power grid connections;

6. Increase the transient steady-state limit;

7. Control reactive power flow, increase the transmission capacity of the line, and maximize the efficiency of the existing power grid.

The Role of CY-SVG in the Application of Distribution Users

1. Improve the voltage quality of the distribution system and increase the qualification rate of power supply voltage;

2. Improve power factor and reduce power grid losses;

3. Suppress voltage fluctuations and flickers caused by impulsive loads

4. Reduce harmonic currents caused by nonlinear loads and improve power quality;

5. Balancing three-phase loads and reducing negative sequence current;

6. Provide transient reactive power support when voltage drops
