The so-called Distributed Power Generation or Dispersed Power
Generation System refers to small power generator that is closed to the
load terminal and the power generation capacity is comparatively less. It
can be formed as area power supply system or can be connected in
parallel to large-scale power system.
For distribution in the past, the Taipower would supply a one-way
power, therefore this was simpler in respect of control, management,
repair or fee collection. However, when there are many dispersed power
generation systems (abbreviated as DG) on the circuit in parallel
connection. At this time, the reliability of the power supply of the
distribution system and the maintenance of power quality and
maintenance of personnel and equipment safety will be more complex
and it will cause impact on the existing distribution system.
This thesis adopts a feeder of Taipower as the research target. The
substation main transformer specification is 3∮69KV/22.8KV 25MW
that provides power for eight nodes. Based on the existing data and after
computer program simulation, one can understand that for the present
utilization of that feeder, the voltage of various nodes can still conform
to the provision of the permissible value of voltage. However, in the
future, that feeder may encounter situation. Beforehand we can adopt
II
computer program simulation. And the author will base on the traditional
method of Taipower and that is general estimate principle to find out the
possible establishment position and capacity of the capacitor on that
feeder. In addition, computer simulation is utilized to prove that the
estimate principle in the traditional way of Taipower is not applicable to
various conditions.
