Due to the deficit of electric energy in Taiwan, the
cogeneration systemis becoming more popular among industries
which require electric energy supply with high reliability. The
problem associated the use of cogeneration systems have been
received much attention by the power engineer. This main
purpose of this thesis is to study the load-shedding scheme
forcogeneration systtems by performing system load-shedding
scheme employs the underfrequency relay for limiting system
overload as well as the overcurrent relay for tripping the tie-
line between the cogeneration plant and the utilitysystem are
demonstrated to verify the validity of the proposed load-
shedding scheme.
