Provides reactive power compensation with improved operational voltage range and small footprint
GE's utility grade Static Synchronous Compensator (STATCOM) solution is a custom designed system to be installed on transmission grids. It provides grid operators with reactive power compensation and improved range of operational voltage with a faster response time and a smaller footprint than traditional SVC solutions.
GE's STATCOM solution leverages Voltage-Source Converter (VSC) technology based on Modular Multilevel Converter (MMC) architecture, from GE's robust High Voltage Direct Current (HVDC) design. The solution is an open-rack structure, where the valve is located inside a building making the accessibility and any required maintenance significantly easier than containerized solutions.
The uniqueness of GE's solution is the larger DC capacitance, a re-usable by-pass switch and industry leading Model-Based design STATCOM control platform.
GE's STATCOM utilizes highly dynamic VSC based compensators, which when compared to SVC solutions, provides improved range of operational voltage, with higher reactive output at lower system voltage and robust recovery support under severe system disturbances and provides a smaller footprint. Key features of STATCOM System include:
•Usually connected to High Voltage (HV) grid via a step down power transformer
•Always a symmetrical power rating in the inductive and capacitive operating regions
•Hybrid solutions available for increased power rating including: STATCOM, plus
-Thyristor Switched Components,
-Mechanically Switched components
-or Static Var Compensator (SVC)
•Reduced footprint compared to a classical SVC solution
