Title:
RAPID PROTECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/024190
Kind Code:
A1
Abstract:
A rapid protection system comprises a two-out-of-three protection subsystem and a double protection subsystem. The two-out-of-three protection subsystem comprises three sets of independent protection devices. The double protection subsystem is embedded into the two-out-of-three protection subsystem. An operation output is separated from the two-out-of-three protection subsystem and the double protection sub-system. By taking both the performance and costs of the protection system into consideration, the rapid protection system is utilized to prevent problem of a delayed protection operation and increased load of the protection system when a fault occurs, providing rapid protection for a serious fault, and increasing the speed, reliability, and stability of the protection system.
