The capacity of a STATCOM (Static Synchronous Compensator) refers to its rated power output, typically measured in MVA (Mega Volt-Amperes) or kVAR (Kilo Volt-Amperes Reactive). The capacity determines how much reactive power the STATCOM can inject into or absorb from the power system to regulate voltage and improve stability.
Distribution Level:
1 MVA to 10 MVA (used for local voltage support in industrial plants or renewable energy integration).
Transmission Level:
10 MVA to 100 MVA (used for grid voltage stabilization and dynamic reactive power compensation).
Up to 300 MVA or more (for large-scale power systems, such as HVDC links or weak grid support).
System Voltage Level:
Higher voltage systems (e.g., 230 kV, 400 kV) require higher MVA ratings.
Reactive Power Demand:
Determined by load fluctuations, renewable energy integration, or fault conditions.
Dynamic Response Requirements:
Faster response STATCOMs (e.g., for wind/solar farms) may have different sizing considerations.
Manufacturer Specifications:
Companies offer STATCOMs in various capacities.
50 MVAr STATCOM: Used for wind farm grid compliance.
±100 MVAr STATCOM: For transmission grid voltage support.
±200 MVAr+ STATCOM: For large industrial plants or weak grid interconnection.
