What is warm standby?

Warm standby , as a type of redundancy technique, has been widely applied to many practical engineering systems, such as computing and power systems . The advantages of warm standby are well reported in the literature. Warm standby outperforms hot standby because it consumes less energy.

What is the difference between hot standby and cold standby?

Different from hot standby and cold standby components, warm standby components usually vary in failure rates or time-to-failure distributions before and after they become operational . Thus, the reliability analysis of warm standby systems usually differs from those of hot standby and cold standby systems.

Do warm standby and storage components compensate for capacity deficiency?

This paper focuses on the reliability assessment of capacity-based systems with warm standby and storage components, which are intended to compensate for the capacity deficiency caused by the failure of operating components.

What is hot standby?

Being in the state ready to operate is known as hot standby. If the electric power deficiency is too large to be balanced or the system is in contingency states, some generating units, whose turbo-alternators are shut down while the boilers are left in hot conditions, can start up and synchronize with the system with a very short lead time [ 9 ].
