sectionalizing switch are absolutely reliable, i.e. the error rate being 0. As to whether the fuse
protector is disconnected or not, it’s designed as: when a random number is given in simulation,
if this random number is greater than the probability of the fuse protector’s reliable disconnection,
it indicates failure in disconnection and vise versa.
As for the simple main feeder system, the key steps for its reliability simulation evaluation are
as follows:
(1) Set the analogue simulation number of years k =0;
(2) k =k + 1; if it reaches the k year, the random number group {r1, r2, r3, ...rn} is generated to
simulate the running state each zone node ...
