Problems solved by technology

[0003] Different boards and cards are responsible for different functions of traditional power system relay protection devices, such as protection sampling, calculation, and communication. The number of internal components in the device is large, there are many information transmission links, and the efficiency of data interaction is low, so the data reliability is low. Once the data processing deviation occurs in the middle link in the working environment of the job site, it will cause abnormal internal operation of the device and affect the safety and stability of the power system

Abstract

The invention relates to a power system relay protection SoC chip, which comprises a main kernel, a slave kernel, a front-end data processing module, an internal memory and a storage management module, and is characterized in that the main kernel and the front-end data processing module are connected with the internal memory, and the main kernel, the slave kernel and the front-end data processingmodule are all connected with the storage management module; the storage management module is used for connecting an external memory; the front-end data processing module is used for being in communication connection with an external device; the front-end data processing module receives analog quantity sampling data sent by an external device and sends the analog quantity sampling data to the internal memory, and the main kernel reads the analog quantity sampling data from the internal memory for logical operation; and data exchange is carried out among the main kernel, the slave kernel and the front-end data processing module through an external memory connected with the storage management module.

Description

technical field [0001] The present application relates to the field of electric power technology, in particular to a power system relay protection SoC chip. Background technique [0002] The relay protection device is a commonly used device in the power system. The working status of the relay protection device directly affects the entire power system, and it is responsible for the important mission of protecting the safe and stable operation of the power system. Therefore, ensuring that the relay protection device operates with high reliability under various working conditions is a problem that must be considered in the design of the relay protection device. [0003] Different boards and cards are responsible for different functions of traditional power system relay protection devices, such as protection sampling, calculation, and communication. The number of internal components in the device is large, there are many information transmission links, and the efficiency of data...
