Embodiment Construction
[0033] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.
[0034] With the rapid development of electronic information technology, more and more industrial control products use SOPC (English: System On Programmable Chip, Chinese: Programmable Chip System), semi-custom chips and even full-custom chips 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 a chip-based relay protection general device 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, protection computing tasks with scheduling accuracy up to 100us level, so that in the ev...

The application discloses a general device for chip-based relay protection, which relates to the technical field of power equipment. The device includes a multi-core processor, the multi-core processor includes a management core, a protection core, a system memory, and a front-end processing circuit, wherein the front-end processing circuit is used to receive the power data of the target power equipment collected by the collection device, and analyze the power data. Perform data analysis, obtain sampled value data, and write the sampled value data into the system memory; the protection core is used to obtain the sampled value data from the system memory, and determine whether the target power equipment is faulty according to the sampled value data, and if the target power equipment exists In the case of a fault, the target power equipment is disconnected from the power grid, and fault information is generated; the management core is used to receive the fault information and generate a fault report according to the fault information. The present application simplifies the original multi-board and multi-CPU system into a single-chip device through a single-chip with high integration, and solves the problem of the increasingly complex structure of the protection device.
Description
technical field [0001] The present application relates to the technical field of power equipment, and in particular, to a general device for chip-based relay protection. Background technique [0002] Relay protection device refers to the failure of power equipment in the power system, such as lines, main transformers, etc., which endangers the safe operation of the power system, by issuing a trip command to the controlled circuit breaker to remove the faulty power equipment from the power supply. A complete set of equipment that is disconnected in the system to prevent the faulty power equipment 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: multiple boards are configured in the relay protection device, data transmission is performed between the boards through a communication bus, and each board is configured with a CPU processor. , Different CPU processors run preset ap...
