Intelligent transformer substation process level message linear processing framework and intelligent transformer substation process level message linear processing method

Abstract

The invention discloses an intelligent transformer substation process level message linear processing framework, which comprises a network processor, a data packet input processing unit and a random storage which are connected with each other. The data packet input processing unit is a hardware co-processing unit and is provided with a network message interface and used for receiving and distributing network message, directly accesses the space of the random storage and simultaneously sends accident information to the network processor. The invention further provides an intelligent transformer substation process level message linear processing method. The intelligent transformer substation process level message linear processing framework is simple, clear in module, strong in expanding performance and suitable for receiving and processing a large amount of network data information of an intelligent transformer substation, removes the message processing bottleneck in the original method, and leads operation of the intelligent transformer substation to be safer and more reliable. The intelligent transformer substation process level message linear processing method can conduct linear receiving and processing on message of the intelligent transformer substation under the premise without processor response interrupting, and solves the bottleneck problems in central processing unit (CPU) data packet receiving and processing caused by high-frequency interruption.

Description

technical field [0001] The invention relates to a network data processing method, in particular to a linear processing framework and a processing method for process layer messages of an intelligent substation. Background technique [0002] As computer and communication technologies are more widely used in the integrated automation system of substations, the secondary equipment of substations and the communication behavior between them are becoming more and more digital and intelligent. The intelligent transformation of substations is in the ascendant. A very important feature of smart substations is that the degree of information sharing has been greatly improved compared with traditional substations. The traditional complex secondary cable connections are gradually replaced by simple optical cable connections. The secondary voltage, current and switching signals are uniform. It is transmitted in the form of a message, in which the voltage and current values ​​are transmitt...

AI Technical Summary

Problems solved by technology

Generally, each SV message contains only one voltage / current sampling point information. For the sampling value information used for protection, the sampling rate is 80 points / cycle. The CPU of the X86 architecture needs to be interrupted every time it receives and parses a data message. Once, in the case of a smart substation, the CPU needs to be interrupted 80 times in one cycle, and 4000 times in 1 second, which will undoubtedly occupy a large amount of CPU resources and reduce the efficiency of receiving and processing messages.
