STATCOM contains connecting reactor (or connecting transformer), start-up device , IGBT converter chain , control system. The system charts as follows: Environment： Operation Temprature：-40℃~40℃ Altitude：3000m Installation: Indoor/Outdoor Protection level： Class Ⅱ QNSVG dynamic reactive power compensation device is a STATCOM system with IGBT as its core, while QNSVG (i.e. the static synchronous compensator) is one of the main equipment employing the FACTS (Flexible AC Transmission System) technology. It represents the new development direction and industrial application trend of reactive power compensation technology for existing power systems; it is an effective method to deal with the threats on grid stability brought by increasing demand of wind power and photovoltaic new energy grid-connection, as well as to protect the safe operation of the power grids. The dynamic reactive power compensation device is one of the key devices in the flexible power transmission system; it can quickly and effectively adjust the reactive power of the grid, prevent the voltage fluctuation and flicker, realize more reasonable distribution of the entire grid power flow, improve the grid quality, and ensure the stable, efficient & superior running of the power system. Advantage: Excellent compensation performance： • STATCOM can alter reactive power dynamically and continuously, and satisfy the compensation requirement of power factor over 0.98 at any moment. The compensation effect of STATCOM is 1.2 times of impedance-type compensation equipments with the same capacity. STATCOM has high investment returns.
