As one of the professional and high quality STATCOM manufacturers, The FGI high voltage Static Var Generator (SVG) has more than 20 years of experience in the application of IGBTs for Static Var Generator`s core components, FGI has developed and manufactured high voltage dynamic reactive power compensation device Static Synchronous Compensator (STATCOM) in 2006 to improve grid stability, increase transmission capacity, eliminate reactive shock, filter out harmonics and balance three-phase power grid.
STATCOM Systems Structure
Three parts: control cabinet, power cabinet, and reactor cabinet. Among them, the power cabinet achieves great uniformity, which facilitates the expansion and stability of product capacity.
Control cabinet is composed of switching device, buffer piece, data acquisition device, control box, logic controller, HMI and secondary power system, the function for every device is switching of the main circuit, bus buffer when the module is charging, switching quantity, analog quantity acquisition, data processing, logical control, set and display parameters and waveform recording, processing the power supply to achieve stability of the control system. Power cabinet is composed of power unit and forced air cooling system / water cooled. the function for each device is cascading signals into specific amplitudes and phases based on voltage, forcing cooling of the module unit. Reactor cabinet mainly contains reactor, the function of reactor is realizing the grid connection of reactive voltage source and filter current.
The basic principle of FGSVG high voltage dynamic reactive power compensation device statcom solutions is to connect the controllable H-bridge circuit to the grid through the reactor, adjust the amplitude and phase of the bridge circuit output voltage, or directly control its output current, so that the circuit absorbs or emits The purpose of meeting the reactive current of the grid demand and realizing dynamic reactive power compensation is shown in the following table.
Zero load operation: U1=Us,IL=0,SVG neither absorbs nor generates reactive power.
Output capactive reactive: U1>Us, IL a leading current whose amplititude can be continuously controlled by adjusting U1, there by continuously adjusting the reactive power generated by SVG.
Output sensible reactive: U1
