Abstract The integration of the southern electrical system with the
balance of Thailand has many desirable features, but technical and
economic problems make this a difficult task. It is over 300 miles
between the nearest practical points of the interconnection. In the
next ten years, there will probably be a maximum load of 300 megawatts
in the southern area. The problem of transmitting power
between the two areas involves a long distance and a relatively low
transmission voltage. Raising the voltage above the present 230 kv
nominal level adds more economic and technical problems than can
currently be solved. However, if the voltage is decreased, the power
loss in transmission becomes excessive and the line itself is unstable
because the angle between the sending end and the receiving end
voltage is excessive.
This thesis presents an analytical evaluation of the electrical
characteristics of this interconnection. Various percentages of shunt
reactor compensation and series capacitor compensation are examined
for feasibility of the interconnection at 230 kv.
It was determined that the transmission line is feasible with the
minimum of 50 percent compensation. The transmission line operation
can be improved by the addition of more compensation, the magnitude
of which must depend upon a comparative economic study.
