Abstract

The invention provides a special main control chip suitable for a power system control protection device. The special main control chip comprises a power special subsystem, a multi-core service main system, a safety subsystem and a storage module; the power special subsystem, the multi-core service main system and the safety subsystem communicate through the system bus, and a plurality of functional processing units are integrated on the chip, so that the hardware architecture of the chip is simplified, the problem of unstable connection of a multi-chip hardware structure is avoided, the reliability and stability of a relay protection system are improved, communication interaction between subsystems in the chip is achieved through a system bus, and the overall performance of the chip is further improved.

Description

technical field [0001] The present application relates to the field of electrical technology, and in particular, to a dedicated main control chip suitable for a power system control and protection device. Background technique [0002] Each component of the power system needs to be equipped with a relay protection device. When a fault occurs in a designated area in the power system, the relay protection device can disconnect the faulty equipment in a very short period of time to ensure the normal operation of the rest of the system and avoid large areas. A power outage occurred. With the increasing maturity of digital technology, chips have been promoted and applied in the field of relay protection of power systems, promoting the intelligence and intelligence of relay protection. [0003] In the current technology, the functional nodes of the relay protection are usually distributed in different chips, and the data exchange between the chips is carried out through the commun...
