SVC (Static VAR Compensator) Problem Solving

SVC is a kind of electrical device applied for providing fast-acting reactive power compensation on high-voltage electricity transmission networks. RXPE, China SVC manufacturer, is able to provide quality static VAR compensator, which can solve the problems in the following areas:

1. Electric Arc Furnace
Electric Arc Furnace may cause a series of adverse effects to the power grid, mainly including serious three-phase unbalance, high order harmonics, severe voltage distortion, serious voltage flicker, and low power factor.
A method of choice to solve the above problems is to install a dynamic static reactive power compensation device (SVC) with quick response speed. Static VAR compensator, with isolated phase compensation function, can eliminate the three-phase unbalance, the harmful high order harmonics, and improve power quality and power factor by providing capacitive reactive power to the system.

2. Rolling Mill
The reactive power impulse caused by rolling mill and other industrial symmetry loads will bring power grid such problems as: severe voltage level drop, voltage fluctuation, power factor reduction, harmful high order harmonics etc.
RXPE’s SVC can perfectly solve the above problems. This power compensation equipment can maintain a stable bus voltage, eliminate the harmonics, and improve power factor.

3. Power Supply of Electric Locomotive
When the transportation way of electric locomotive preserves the environment, it may seriously pollute the power grid. As the electric locomotive has single phase power supply, which may cause serious three-phase unbalance, low power factor, and negative sequence current.
However, there is a preferred way to solve the above problems, that is, to install SVC at appropriate locations along the railway. Quick isolated phase compensation function of this electrical equipment can ensure the three-phase balance, and the improved power factor is achieved through filters.

4. Hoist
Hoist and other heavy loads may have the following effects on power grids at work: voltage level drop and voltage fluctuation, low power factor and harmful high order harmonics. With RXPE’s Static VAR compensator, there is no need to worry about these problems.

5. Long-distance Power Transmission
In electrical engineering, long-distance power transmission is a growing trend. It demands the transmission and distribution system to be more effective. RXPE’s SVC can significantly improve the transmission and distribution performance of power system, such as transmission loss reduction, reduced power fluctuation, increased transmission capacity and transient stability limit etc.

6. Secondary Substation in City (66/110 kV)
In regional power grid, we generally use the TSC for reactive power compensation and improved power factor. But it can not achieve rapid and precise regulation with the changes of load which is easy to cause inverted injection of reactive power to the system. Therefore, RXPE’s SVC is needed to quickly and accurately make capacitive and inductive reactive power compensation.
