Problems solved by technology

[0004] The biggest obstacle faced in the process of substation automation system integration is the different communication protocols and user interfaces used by IEDs from different manufacturers, or even different models of IEDs from the same manufacturer, making it difficult to achieve seamless integration and interoperability
Because additional hardware (such as protocol converters) and software are required to realize IED interconnection, and user training is required, this greatly weakens the advantages and significance of substation automation

Abstract

The invention discloses an embedded sub station based on a CPCI bus. The sub station comprises a CPCI bus, a main control module connected on the CPCI bus, an Ethernet communication module, a serial interface communication module and a GPS clock time-setting module, wherein, the main control module is sequentially connected with a man-machine interface module, a data storage device, an Ethernet controller and a serial interface communication transceiver, and each of the Ethernet communication module, the serial interface communication module and the GPS clock time-setting module comprises a PCI slave device controller communicating with the CPCI bus. The utility model has the advantages of possessing the interoperability, the scalability, and the high reliability, completing the device linkage, the protocol conversion, the data standardization and transmission, and the like, realizing the monitoring, control and management of a secondary device, adopting the modularized design so as to enable the system to have expandability, being added with relevant modules according to the requirement of a customer, and providing the possibility to the high reliability realization of the system.

Description

technical field [0001] The invention relates to the field of substation automation communication, in particular to an embedded substation based on CPCI bus used in a substation automation system. technical background [0002] In addition to the three major functions of control, monitoring and protection, the functions of the substation automation system also include the maintenance functions of the substation automation system, that is, system configuration, communication management and software management. [0003] The substation automation system can integrate the originally separated control, protection, monitoring, communication and measurement devices in a suitable form, and the automation system is composed of a small number of multifunctional intelligent electronic devices (Intelligent Electronic Device, IED). Realizing information sharing can greatly reduce signal cables and simplify system structure. This not only improves the economy of the system, but also improv...
