3.3kV-Series TSVG(STATCOM)

Product description

With SVC as its predecessor, SVG is a new reactive compensation apparatus, characterized by fast response speed, wide compensation scope and small land occupancy. It is particularly suitable for being applied to such market areas with frequent load variations as new energy power generation, steel and railroads.


Technical Advantages

The company has mainly produced high-low voltage SVG, wind and PV grid-connected converters, key control apparatuses for flexible DC Power T&D and other power electronic apparatuses. Its flexible power transmission products, with the advantages of greatly improving the flexibility of the Power T&D grid and the system stability, are mainly applied to renewable energy power grid connection, synchronization/asynchronization interconnection of power grids, power capacity expansion for urban load centers and remote isolated load power supply.

The randomness and intermittence of new energy power generation would influence whether the power system is reactive or not and cause the fluctuation and flicker of voltage. What’s more, the low-voltage fault in the system would impact the grid connection of inverters. TSVG can exercise dynamic adjustment to the reactive work, stabilize the bus bar voltage, reduce the reactive output of converters and improve the stability of new energy power stations.


Regional grids have a large number of inductive loads and relatively low natural power factors, causing the increase of line drop and transmission losses. Besides, it also lowers the power supply capacity of Power T&D apparatuses and output of electric apparatuses. TSVG can realize the reactive compensation for grid, meet the requirements for the power factors and power quality of the power system and gain the huge benefits of energy-saving and cost-reducing.


In operations, electric trains use single-phase rectification loads, thus producing reactive current and harmonic current and exerting severe influence on the power supply systems and power quality on the trains. The reactive harmonic wave has increasingly become the top concern demanding prompt solutions for electrified railways. The single-phase TSVG can exercise dynamic adjustment to the reactive power of the power supply system and the filter FC can effectively remove the higher harmonic current produced in the trains operation.


The charge effect of subway cable makes subway system in the reactive state of at night, which causes the rise of bus bar voltage and threatens the stability of power apparatuses. TSVG can give targeted reactive compensation to subway systems, stabilize the bus bar voltage, increase power factors and completely address the reactive problem.


In running, electric-arc furnaces generate fast changing reactive current, negative-sequence current and harmonic current. The fast changing reactive loads make grid voltage fluctuate and flicker greatly. TSVG can rapidly and precisely detect the reactive current and negative-sequence current and output the compensation current within 5 ms. This way, it can improve the power factors of the system, restrain the voltage imbalance of the grid, stabilize bus bar voltage and restrain voltage flickers to the best.
