Flexible AC Transmission Systems Projects List
A flexible alternating current transmission system (FACTS) is a system composed of static equipment used for the AC transmission of electrical energy. It is meant to enhance controllability and increase power transfer capability of the network. It is generally a power electronics-based system.
FACTS is defined by the IEEE as “a power electronic based system and other static equipment that provide control of one or more AC transmission system parameters to enhance controllability and increase power transfer capability.”
According to Siemens “FACTS Increase the reliability of AC grids and reduce power delivery costs. They improve transmission quality and efficiency of power transmission by supplying inductive or reactive power to the grid
A number of benefits can be attributed to the use of FACTS in power systems: They include:
a. Dynamic voltage control: Its main selling point is to limit over-voltages over lightly loaded lines and cable systems, and prevent voltage depressions or collapses in heavily loaded or faulty systems.
b. Increased power transmission capability and stability: Power networks can easily be stabilized without the need of installing new lines. This benefit is highly attractive because of cost reduction obtained from not installing new power lines. It also impacts on the environmental factors and restrictions placed on the complex expansion of networks.
c. Facilitation of renewable generation connection to the grid: Since FACTS has the characteristic of stability, renewable power generation could easily be connected to the grids with the aid of FACTS and thus fulfill the necessary grid code demands.
