Problems solved by technology

[0004] At present, the research technology on the reliability of smart substation communication system is mainly to express the logical relationship between components through the reliability block diagram, and to solve the availability and unavailability of the system by using methods such as fault tree, minimum path set or state space. The probability of availability and unavailability can only be used to obtain the possibility of each component and the system when it is in a normal working or fault state, but it cannot obtain the sensitivity of the component to the reliability of the system, and it cannot be obtained that each specific component affects the entire system. The impact trend and degree of reliability, so there is no effective pertinence when taking measures to improve system reliability
