Dynamic reactive power compensation
Dynamic Reactive Compensation
Providing stability, security, and reliability to the grid
Installing a STATCOM at one or more suitable points on the network
is a powerful and cost effective method to increase grid transfer
capability and enhance voltage stability.
What is a STATCOM?
A STATCOM (or Static Synchronous Compensator) is a voltage
regulating device. It is based on a power electronics voltage-source
converter and can act as either a source or sink of reactive AC
power. It is a member of the Flexible AC transmission system
(FACTS) family which detects and instantly compensates for voltage
fluctuations or flicker, as well as controls power factor.
As a fully controllable power electronic device, the STATCOM is
capable of providing both capacitive and inductive VARs. ABB’s LV
STATCOMs can be rated at up to +/-30 MVAR although larger sizes
are possible.
STATCOM Applications
Electrical utilities and heavy industries face a number of challenges
related to reactive power. Electrical utilities may be confronted with
voltage sags, poor power factor and even voltage instability. Heavy
industrial applications can cause disturbances like voltage
unbalance, distortion or flicker on the electrical grid. Reactive power
control can resolve these issues by improving the power factor or
compensating for the voltage instability. In many cases, the
traditional solutions of switching capacitors is too coarse and slow
to stabilize a weak network.
The most advanced solution to compensate reactive power is to
incorporate a Voltage Source Converter (VSC) as a variable source
of reactive power. These systems offer advantages compared to
standard reactive power compensation solutions in demanding
applications, such as wind farms and arc furnaces, where normal
reactive power control generated by generators or capacitor banks
alone are too slow for the sudden load changes.
3 phase grid
