碩士 === 大同大學 === 電機工程學系(所) === 94 === ABSTRACT 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.
