Summary: | 碩士 === 國立中山大學 === 電機工程研究所 === 84 === Feeder load unbalance is one of the prime reasons to cause
line losses in the distribution system.To enhance the operati-
onal efficiency and reduce cost,effective methods are required
to resolve. In this thesis , Fuzzy algorithm technique is
developed for distribution network reconfigurations to
minimize feeder losses. Two membership functions were
defined for tie-switch selection and another two membership
functions were developed for the optimal sectionalizing switch
selection. Through the "set" operations of all the membership
functions, the optimal on-off switch pairs can be
determined.In addition,a trans- former management algorithm
based on the linear programming was also developed for the
distribution system. Linear progra- mming will mix up various
load types according to an optimized proportion to increase
transformer utilization factor and reduce system losses. One
system of the Taipower company and another five selected
examples were choosen for tests in this thesis. It can be
shown that the fuzzy algorithm is effective enough to obtain
optimal or near-optimal solutions for distribution feeder
reconfigurations and linear programming method performs satis-
factorily for transformer load management to reduce system
losses.
