Embodiment Construction

[0024] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] In the present invention, FPGA is responsible for peripheral interface signals, and multiple DSPs are used as computing chips, which are the cores for realizing algorithms. FPGA receives external data through the high-speed communication IO port. The high-speed interface includes optical fiber interface and electrical interface, and the speed can be as high as 100M, so that fast information exchange can be realized, and it is transmitted to multiple DSPs by using parallel bus technology. The DSP receives the data sent by the FPGA, and after filtering logic processing, sends the judgment result to the FPGA, and the FPGA receives the processing result of the DSP, and sends the relevant results to the background human-machine interface and the execution device respectively according to the requirements of the flexible straight s...

Abstract

The present invention provides a device for multi-DSP data exchange based on an FPGA. An FPGA is configured to process peripheral interface signals, a DSP is taken as an operation chip, and the exchange device comprises an analog quantity signal processing module and a switch quantity processing module. A CPU board card designed by the technical scheme of the invention is improved in multiples inprocessing capacity; and moreover, a task requiring processing is converted from serial processing to parallel processing to shorten in multiples a task processing period and greatly improve real-timeresponse capacity of a control protection device.

Description

technical field [0001] The invention relates to the field of flexible DC transmission control and protection systems, in particular to an FPGA-based multi-DSP data exchange device and exchange method. Background technique [0002] The flexible DC transmission control and protection system is one of the core components of the flexible DC transmission system. It is responsible for realizing complex control functions such as AC-DC conversion, DC transmission power and voltage control, AC system reactive power and voltage control, as well as AC area protection, Protection functions such as DC area protection and valve area protection. With the increase of the voltage level and capacity of the flexible direct current transmission system, higher requirements are inevitably put forward for the performance of related control and protection systems. The high-voltage and super-large-capacity flexible DC system has complex control functions, various protection configurations, and real...
