Abstract:
The objective of this thesis is to investigate and study problems and voltage
congestion facing the engineers involved into the operation of a network of the
National Authority for electricity in Khartoum region. The thesis looked into the
effects that advanced control techniques have on electric compensation of power
generation and transmission system.
The thesis explained first the power system components of National
Electricity Corporation such as the generation quantity and types, substation,
transmission line and voltage control procedures which are used. It then proceeded
to give a brief introduction to the location of Khartoum ring and purpose of its
establishment.
A load flow studies is made for the network of the National electricity
corporation by using actual value of networks (busbars voltage, loads at peak load,
line parameter, capacitors and reactors rates and types, rates of generation and its
MVAr limitations).
A load flow program (HADI SADAT load flow program) is applied for
improving of voltage deterioration in Khartoum ring in two cases, first one is
operating the costly units in minimum load and the second case is totally shutdown
of costly units. Some results are obtained appear that problem which is expected,
and some solutions are discussed for this problem.
The thesis studied the dependence on Marawi dam for generating electricity
and possibility of shutting down the costly unit (thermal power station in KHN and
GARI complex), the contribution of costly unit in reactive power compensation in
Khartoum region and possibility of constructing compensation units for reactive
power management.
