With the highly strict demand of data synchronicity in the protective device of substation, the merging unit's synchronization delay, from data collecting to data sending, should be both short and stable. However, the calibration time is usually not precise in current substations. In order to solve the problem that sampling data is not synchronous, this paper designs a kind of system using FPGA based on Newton interpolation algorithm. This algorithm takes advantage of sampling information of the merging unit's accurate arriving time and packet's delay time to calculate the corresponding sample in local time. Then it can get the sample information of different merging units at the same local time using interpolation calculation. Compared with the traditional way, this method realizes sample value synchronization without external synchronous clock source. This system receives data from multiple merging units, and then sends to bay layer unit to use after data synchronization. In power system, the processed delay of sample value is less than 10us, which is really difficult for CPU. So FPGA is used in this system. Being adopted modular design to make each sub-module collateral execution, the speed level is ns. The simulation and experiment results demonstrate the validity of the proposed method, and this system is very meaningful and important to the automation development of the power system.

“…GOOSE and SV messages are directly mapped to the link layer in order to provide fast response time, because they are used in critical services [5]. Hence, these messages are directly encapsulated in the Ethernet Protocol and transmitted with a multicast destination MAC address [9]. The Substation Configuration Language (SCL), also defined in the standard, guides the system configuration.…”

“…It happens because typical L2 switches treat multicast traffic as unknown and broadcast it in order to guarantee that all potential receivers will be achieved. This procedure consumes link bandwidth, increases latency at switches, and introduces significant overhead at receiving IEDs [9,11].…”

Smart grids depend on a solid foundation of communications. Although standards like IEC 61850 proposes interoperability, autoconfiguration, and autonomous control solutions for the communication network, there are still open problems on how to efficiently forward high priority sensitive data. This work proposes a complete architecture for autonomic management and control of communication networks for substations based on IEC 61850. The proposed solution, called SMARTFlow, uses OpenFlow in order to achieve granularity and flexibility in the treatment of data flows. SMARTFlow proactively calculates Layer 2 multicast trees to forward the high priorities GOOSE and Sampled Values messages and reconfigures all flow entries in case of network failures. Also, the proposed system monitors the network and defines the configuration of client-server flows on-demand. The proposal was implemented and tested using Mininet and showed a total load up to 44 % lower than the load using typical switches.

-At present there is an exigency in both software and hardware for emulation of measured sampled values transmission of electrical power parameters in order to test the digital substation equipment. Necessary software emulators implementing full functionality described in the standard IEC 61850 are still not exist. In the paper the software for emulating the transmission of measured sampled values in accordance with IEC 61850-9-2 and IEC 61850-9-2 LE is presented. It emulates transmission of sampled values at 80 or 256 samples per period for phase and neutral line sinusoidal currents and voltages and testing of digital substation equipment.
