Example 1: a fault wave recording circuit.
The method is used for realizing compatible access of fault wave recording to IEC 61850-9-2 sampling value SV data based on Ethernet and substation event GOOSE data facing a general object, and IEC 60044-8 protocol and custom data frame format based on serial communication, and comprises the following contents: a hardware circuit capable of uniformly and compatibly accessing Ethernet and serial communication is designed and realized.
The invention improves the standardized manufacturing level of products.
The utility model belongs to the technical field of power systems and automation thereof, and relates to a digital sampling data compatibility and product production standardization technology of a power system secondary equipment fault wave recording device aiming at different communication protocols.
The fault wave recording device is a secondary device for relay protection of a transformer substation, and has the main task of recording the change process of relevant system electrical parameters (current, voltage, switching value and the like) before and after the occurrence of large disturbance of a power system and the action behavior of a relay protection and safety automatic device, thereby providing assistance for disturbance analysis and being equivalent to a black box for operation of the transformer substation. With the popularization of intelligent substation schemes with important characteristics of analog quantity sampling digitization and data transmission networking, analog quantity and sampling value of switching value of a substation are converted into digital quantity and transmitted to a fault wave recording device in a network or point-to-point mode, the device extracts current, voltage analog quantity and switching value from a message to record, and two digitization access modes are generated in the digitization development process of the substation, namely an access mode based on IEC 61850-9-2 sampling value SV data of an Ethernet and substation event GOOSE data facing a general object, and an access mode based on IEC 60044-8 protocol of serial communication and a custom frame format. Both are optical signal transmission, but each has different physical characteristics of an interface and an application layer protocol, so that the physical characteristics and the application layer protocol cannot be unified, and the obvious problem in the current production practice is that the physical interfaces are not compatible. The general wave recording product adopts the plug-ins of different interfaces to respectively receive, so that different access requirements are met in a way of replacing the plug-ins, the product standardization level is low, and the production efficiency is influenced. Under the application scene of simultaneously accessing the data of two protocols, the plug-in configuration is complicated, and engineering design and field debugging are inconvenient.
The technical problems to be solved by the invention are as follows: the fault wave recording device solves the problem that the existing intelligent substation fault wave recording device is compatible with different protocol data, and provides a fault wave recording multi-protocol compatible access technology which is used for realizing compatible access of fault wave recording to ICE 61850-9-2 sampling value SV data based on Ethernet and substation event GOOSE data facing a general object, and IEC 60044-8 protocol and custom data frame format based on serial communication.

Second, pins of the optical module were redefined, and 2, 7 were used as the receiving pins for IEC 60044-8 data. The conflict is not avoided, the Ethernet optical module also adopts a customization mode, the 2 pin and the 7 pin of the Ethernet optical module are set to be idle, and the pin functions of the Ethernet optical module are realized in other modes inside the Ethernet optical module. Thus, two optical modules with identical mechanical dimensions are used for respectively realizing the dual-receiving of Ethernet receiving and transmitting and serial communication, and realizing the compatibility of physical interfaces. The functional block diagram is shown in fig. 4. When the Ethernet message is required to be received, a customized Ethernet optical module is inserted, and pins 12, 13, 18 and 19 receive and transmit Ethernet data; when the ICE 60044-8 data needs to be received, a customized ICE 60044-8 optical module is inserted, and two paths of protocol data are received by the pins 2 and 7.
