Embodiment Construction
[0033] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.
[0034] With the rapid development of electronic information technology, industrial control products are increasingly using SOPC (English: System On Programmable Chip, Chinese: Programmable Chip System), semi-custom chips and even full-custom chip ASIC (English: Application Specific Integrated Circuit, Chinese: integrated circuit chip) to achieve. Based on chip technology, it is a technical hotspot in this field to study chip-based relay protection general-purpose devices based on a single chip.
[0035] In practical applications, the relay protection system needs to have the following two functions. On the one hand, it can complete high real-time tasks, that is, to dispatch protection calculation tasks with an accuracy of 100us, ...

The invention discloses a chip-based relay protection universal device, and relates to the technical field of power equipment. The device comprises a multi-core processor, the multi-core processor comprises a management core, a protection core, a system memory and a front-end processing circuit, and the front-end processing circuit is used for receiving power data, collected by collection equipment, of target power equipment, carrying out data analysis on the power data to obtain sampling value data and writing the sampling value data into the system memory; the protection core is used for acquiring sampling value data from a system memory, determining whether the target power equipment has a fault or not according to the sampling value data, disconnecting the target power equipment from a power grid under the condition that the target power equipment has the fault, and generating fault information; and the management core is used for receiving the fault information and generating a fault report according to the fault information. An original multi-board card and multi-CPU system is simplified into a single-chip device through a high-integration single chip, and the problem that the architecture of a protection device is increasingly complex is solved.
Description
technical field [0001] The present application relates to the technical field of power equipment, in particular to a chip-based relay protection universal device. Background technique [0002] The relay protection device refers to the power equipment in the power system, such as the line, the main transformer, etc., when a fault occurs, which endangers the safe operation of the power system. It is a complete set of equipment that is disconnected in the system and prevents the power equipment that fails from affecting the safe operation of the power system. [0003] In the prior art, the structure of the relay protection device is generally as follows: a plurality of boards are arranged in the relay protection device, and data transmission is performed between each board by means of a communication bus, and each board is equipped with a CPU processor , Different CPU processors run pre-set application programs to realize different functions such as data sampling, message anal...
