| Summary: | 碩士 === 國立臺灣科技大學 === 工程技術研究所 === 81 === This thesis is based on the planning of the optimal trunk
system network of the Taiwan Power Company(TPC) system in
2006. It sets up the long term goal for the mid-term and
long term trunk network structure, so that the future
expansion of the trunk network can satisfy the sysetm
operational security requirement, reliability, and economy in
the future. The thesis applies the method of sensitivity
factors on the planning of reactive power. First, it
applies voltage sensitivity factor to perform the optimal
planning of reactive power compensation so that all bus
voltages can be regulated to within their limits under the
least cost. Then, the power flow factor are used to
estimate more precisely and quickly the apparent power flow
of the remaining transmission lines under contingency cases.
The last part applies the reactive power loss factors to
analyze the planned-system tap ratio positions of
transformers. Not only a good voltage profile can be
reached but also the system power loss can be reduced.
