IEC 61850 is a standard for the design and operation of electrical Substation Automation Systems (SAS) that defines how data may be transferred among Intelligent Electronic Devices (IEDs). The defined data models can be mapped into application protocols, such as SV or GOOSE, which may run upon high speed Ethernet LANs bridged by IEEE 802.1Q compliant switches. The communication system must cope with the timing requirements associated to protective relaying strategies. Given the time constrained nature of SAS applications, a thorough analysis of its timing behavior is required. In this paper, we propose an analytical model for the timing assessment of SV and GOOSE message exchanges in an IEC 61850 process bus. The proposed model allows the communication timing assessment, by analyzing the response time of each message stream of the SAS. This feature is an advantage for the expansion of the SAS, as it allows the evaluation at design time of the maximum number of IEDs that can be supported by the underlying communication system. The results from the proposed analytical model were validated for a typical IEC 61850 communication scenario, both through simulation and through an experimental assessment with IEC 61850 compliant equipment.

“…III-B. Since the STFT of real signals is symmetric in magnitude and all integer numbers are also real numbers, only the spectral components corresponding to positive frequencies are estimated and the magnitude is multiplied by 2, as shown in (8). The highest positive frequency after the 2 nd decimation stage corresponds to the Nyquist frequency given in (7).…”

“…Since the set of basis vectors {ψ k } is orthogonal and each element has norm L H,m , the results are normalised by the length of the STFT window 1/L H,m in the analysis formula (8), which considers a rectangular window. Additionally, the estimated amplitude of the k th spectral component is divided by √ 2 in order to obtain the RMS value.…”

“…This type of architecture is referred to as centralized substation protection and control (CPC) as specified in [5] and is expected to foster new centralized functions such as dynamic state estimation-based protection schemes [6] at the substation level. Most of the proposed CPC architectures use merging units (MUs) to publish sampled values (SV) of the current and voltage signals on the process bus as in [7] and in [8], while the digital signal processing (DSP) algorithms and protection logic are executed on the centralized platform. This approach has two drawbacks.…”

Travelling-wave and time-domain-based protection functions provide significant response time improvements over conventional phasor-based protection functions in power systems. These types of protection functions require very high sampling rates in the order of several hundreds of kHz. This paper proposes a novel centralized substation protection architecture (CPC) based on distributed signal processing units (DSPU) that enables the deployment of these high sampling rate applications in digital substations utilizing an Ethernet-based process-level network. The design of the DSPU is elaborated, and its signal processing algorithms are discussed. Moreover, the performance of the DSPU is analysed through dynamic tests and verified through a numerical electromagnetic transient simulation.

Communication-assisted protection and self-healing control (CAPSC) is perceived as a new alternative to ensure reliable operation of distribution networks (DNs) because of its prominent advantages of information sharing. Although the application of CAPSC based on IEC 61850 has been verified in substations, it has not yet been effectively promoted in DNs. To fully exert its advantages in DNs, a novel scheme of IEC 61850-based CAPSC is proposed in this paper. The proposed scheme enable samplings to be synchronized by propagation delay compensation without external clocks. Adaptive execution algorithms of protection and self-healing control are introduced considering changeable topology and configuration conditions. The coordination between protection and self-healing control in this scheme is simplified by component state descriptions instead of event signals. The scheme proposed in this paper has been incorporated in an engineering field application. A closed-loop test has been conducted on a real-time digital simulator (RTDS) according to the field connections and parameters to verify the rationality and effectiveness of the proposed scheme.INDEX TERMS Distribution networks, IEC 61850, protection and self-healing control, RTDS.
