Research on Static Synchronous Series Compensator (SSSC)
Abstract:As the development of the economy of our nation, electric power demand increased rapidly, the scale of power system continues to
expand, and the dependence and demand of people to electric power
is higher and higher. So the require of electric grid’s
reliability is higher and higher. In recent several years great
attention is paid to the anomalous system and its control measure.
The appearance of FACTS device brings new control techniques and
approaches, which can control system voltage and compensate
reactive power, then keep system voltage stable. This article
analyses the meaning and limitation of keeping the system stable,
it introduce the appearance of FACTS and some device of the family,
it compare TCSC and SSSC simply .It lead to Static Synchronous
Series Compensator (SSSC), it also recommend the present situation,
the insufficiency of SSSC at home and abroad, the study content
of this article is given a briefly presentation too. Then this
article expound the basic theory and construction of SSSC, then
it analyses the system steady and the action of SSSC on keeping
the voltage steady, afterwards this article explains some
influences of the SSSC on relay protection. This essay include the
math modeling and simulation design of system which include SSSC,
then explain the procedure of the simulation simply and give the
result of the simulation, all this show the advantage and function
of SSSC in improving system’s running condition, enhancing
system’s stability, increasing electric network’s transmission
ability
