Abstract
In order to achieve the “first-class work” construction goal, the original scheme
focusing on the demand of the electric power system is changed into the other bined with
the user’s demand. The line switch protects transient time of the instantaneous period in the set-
ting value strategy, and coordinates with boundary switch protection. It extends the original pro-
tected boundary to important users downstream, and coordinates with the transformer substa-
tion upstream, forming a set of relatively constant value based on the substation transformer. At
the same time, with the coordination of boundary switch, intermediate switch of long transmis-
sion lines and its related protection section, the characteristics of the original protection scheme
are e, namely, relying on the length of transmission lines and failure to guarantee the se-
lective coordination because of the influence of the operation mode. On this basis, the “county ad-
justment setting integrated system” can be effectively achieved so as to realize the automation of
work setting management.
