Abstract:
The fast growing of cities and population led the industrial section to
grow as well, in addition to the domestic loads, this rapid increase in load
demand forces power systems to operate under heavily stressed conditions,
near critical limits due to economic and environmental constraints .
To avoid power systems collapse, improve the voltage stability, and
reduce the transmission lines losses, the Flexible Alternative Current
Transmission System (FACTS) it used. In this dissertation the Static Var
Compensator (SVC) has been represented and discussed.
Sudanese national grid is undergoing changes as a result of constant
power demand increase, thus stretching it beyond their voltage and thermal
limit. This drastically affects the power quality delivered. Transmission
systems should be flexible to respond to generation and load patterns, then
incorporate this device in Sudanese grid to enhancement the performance.
Simulations are carried out using (PSAT) package in (MATLAB) software.
The results obtained showed the effectiveness of SVC on voltage profile,
power losses and power transfer through the line in the Sudanese national grid.
