What is Statcom?

STATCOM stands for Static Synchronous Compensator,  in China, we named it as high voltage Static Var Generator. It a power electronic device in electrical power systems provide voltage support, reactive power compensation, improved power quality.

STATCOMs are typically connected to the grid at the point of common coupling (PCC) and act as shunt-connected voltage source converters to control the flow of reactive power. They are capable of injecting or absorbing reactive power into the grid to maintain a desired voltage level and compensate for reactive power imbalances.

What are statcom's benefits?

Here are some of the functions and benefits of STATCOM:

Voltage Stability Improvement: STATCOMs can regulate the voltage at a certain point in the electrical network, helping to maintain steady and stable voltage levels under varying load conditions. This enhances the stability and reliability of the power system.

Reactive Power Compensation: STATCOMs can provide or absorb reactive power to improve the power factor and reduce reactive power losses. It helps in reducing voltage drops and improving the overall efficiency of the power system.

Voltage Flicker Mitigation: STATCOMs can mitigate voltage flicker caused by rapidly changing loads, thereby improving power quality for sensitive equipment.

Grid Integration of Renewable Energy: STATCOMs can be used to enhance the integration of renewable energy sources such as wind, solar, or hydro power into the grid. They can compensate for the intermittent nature of these sources and help maintain stable grid operation.

Fault Ride Through Capability: STATCOMs can provide fault ride-through capability by injecting reactive power during system faults, helping to maintain grid stability and prevent cascading failures.

Overall, STATCOMs are important devices in modern power systems as they provide dynamic and flexible control of reactive power, voltage stability, and power quality, enhancing the efficiency and reliability of the electrical grid.
