Abstract:

The development of the Ukrainian electricity sector in terms of energy independence and energy saving is directly related to the introduction of so-called Smart Grid technologies — the construction of intelligent electrical networks. That, in turn, requires their automation, and first of all — electric substations, and, consequently, the introduction of a number of standards harmonized with international ones. Such standards are: IEC 61850‑1 IEC 61850‑6; IEC 61850-7 ÷ IEC 61850-7-5); IEC 61850-8-1; IEC 61850-9-2; IEC 61850-10. Based on the analysis of these standards in the article presented, from the conceptual point of view, the perception in the understanding of the basic concepts of modeling and description methods for information models of stations and substations, the functions of devices used in the automation of substations and communication systems to provide interoperability within substations.

Abstract:

Process bus communication has an important role to digitalize substations. The IEC 61850-9-2 standard specifies the requirements to transmit digital data over Ethernet networks. The paper analyses the impact of IEC 61850-9-2LE on physical protections with (analog-digital) input data of voltage and current. With the increased interaction between physical devices and communication components, the test proposes a communication analysis for a substation with the conventional method (analog input) and digital method based on the IEC 61850 standard. The use of IEC 61850 as the basis for smart grids includes the use of merging units (MUs) and deployment of relays based on microprocessors. The paper analyses the merging unit's functions for relays using IEC 61850-9-2LE. The proposed method defines the sampled measured values source and analysis of the traffic. By using neural net pattern recognition that solves the pattern recognition problem, a relation between the inputs (number of samples/ms—interval time between the packets) and the source of the data is found. The benefit of this approach is to reduce the time to test the merging unit by getting the feedback from the merging unit and using the neural network to get the data structure of the publisher IED. Tests examine the GOOSE message and performance using the IEC standard based on a network traffic perspective.

Abstract:

To meet the requirements of smart substations for digital information, integrated functions and compact structure, the definitions of merging units in IEC 60044-8 and IEC 61850-9-1/2 were analyzed. Based on the analysis, this paper described a realization of merging units used in the electronic transformers. The hardware and software architectures of merging unit were proposed. According to the design, the merging unit realizes synchronization of sampling pulse, receiving and processing of sampled values, and data transmission. An additional function of phasor measurement was included, which makes it a synthesized device between the process level and the bay level of the digital substation. The data packets were captured and analyzed by Wireshark, corresponding with IEC 61850-9-2, which demonstrates the high flexibility and utility value of the merging unit.

Abstract:

Purpose This paper aims to focus on the implementation of the International Electrotechnical Commission (IEC) 61850–9-2 standard based process bus with merging units (MUs) and sampled values (SV) to improve the protection and control systems. The digital process interface is important to be included on the process bus level. Design/methodology/approach The IEC 61850–9-2 process bus standard is not extensively used in regard to SV when the IEC 61850 standard is implemented by power utilities. Many protection and control intelligent electronic devices (IEDs) are connected to a substation communication network, routers and switches using fibre-optic linked Ethernet. However, inductive current transformers (CTs) and voltage transformers (VTs) secondary circuits are still hardwired to the IEDs. The paper highlight issues with the copper wires for currents signals and how these issues can be eliminated by using the MUs and the SV protocol. The voltage regulator control IED of each transformer is required to regulate the voltage level of the secondary side bus bar it is connected to. All the regulating IEDs of parallel-connected transformers are required to communicate with each other to share information. They collectively control the bus bar voltage depending on the switching configuration of the parallel transformers. Findings It is shown that process bus information such as the high voltage switchgear status information of primary plant in the yard, can be used to improve the substation protection and control systems. The power transformer protection and voltage regulator control are focused on. Research limitations/implications The deliverables of the research work can be applied in: The Centre for Substation Automation and Energy Management systems of the Department of Electrical Engineering, power utilities and other establishments using power systems and digital substations in the electrical supply industry. The research work on the thesis led to the development of a laboratory test-bench where students can learn and understand the basics of the IEC 61850–9-2 SVs principles. The test-bench components such as the IEDs, real-time digital simulator, standalone MUs and Ethernet equipment can be used for future research applications. The test-bench can be used to demonstrate during course work for students at the University, the basics of digital substations using a process bus network with IEDs, MUs and Ethernet equipment. Practical implications The research work showed where lab equipment is getting outdated and future equipment will be required for research work in IEC 61850–9-2 process bus. Originality/value Power utilities can benefit from implementing the IEC 61850 part 9–2 of the standard and by using MUs and other process interface information in substations. A cost reduction in high voltage equipment, substation installation and commissioning costs and better performance of protection and control system can be achieved.

Abstract:

IEC 61850-9-2 proposes the process bus communication for protection and automation within substations. The actual performance of process bus such as real-time, security and reliability are of concern, when transmission of sample values and trip signals over the same network. This paper presents the establishment of a dynamic simulation test platform, in order to facilitate the test of protection schemes over the process bus. An example is given to demonstrate that incorrect switch configuration, message priority tagging, and the volumes of traffic on the network may have an impact on the real time and reliability of the signals to be delivered.

Abstract:

A transformer protection scheme using fault component computed from instantaneous measurement values is proposed in this paper. The algorithm utilizes reactive power directional elements computed from the received IEC 61850-9-2 sampled values, and uses the ratio of active and reactive currents to determine an inrush condition. A transformer fault is declaimed if the directional elements from all transformer terminals seen the fault in its forward direction. Extensive simulation tests show that the proposed algorithm is sensitive to detecting faults, and is able to distinguish faults internal or external to the protected transformer zone, and to discriminate a fault from inrush conditions.

Abstract:

<p class="Abstract">Merging Units (MUs) play a key role in enhancing the levels of security and the reliability of power systems, allowing for advanced remote diagnostics. Some of the benefits are a more efficient transmission of electricity and a better integration with renewable energy systems. In this article, an implementation of a Stand-Alone Merging Unit (SAMU), compliant with the IEC 61850-9-2 standard and based on a low-cost ARM microcontroller, is described. It acquires two signals, one voltage and one current, and it sends the samples over the ethernet connection. A high-resolution Analogue-to-Digital Converter (ADC), synchronised to the Universal Time Coordinated (UTC) through a Global Positioning System (GPS) disciplined oscillator, is used. The opportune insulation and conditioning stage have been designed. Several tests have been performed, varying amplitude, frequency, and phase of the input signals, in order to evaluate the metrological performance of the proposed SAMU and they are here discussed.</p>

Abstract:

In the integrated power supply systems SMART-Grid, energy effici-ency, reliability, and survivabilityare ensured, to some extent, by continuous monitoring of the stability of parameters with reference to real-time signals. In accordance with the ІЕЕЕ С37-238-2017 standard, in order to provide power supply system with the time stamps, it is necessary, with respect to the concept of intelligent power sys-tem SMART Grid, to develop and implement the means for reproducing accurate time stamps with a microsecond accuracy. A protocol, which is capable to meet these re-quirements and does not require the development of a dedicated power system is the PTP protocol. The developed state standard of Ukraine DSTU IEC / IEEE 61850-9-3: 2018 defines a number of characteristics of the PTP protocol for both energy and other profiles. A full standardization of PTP protocol in Ukraine requires a development and adoption of the following document-based standards as the state’s ones: IEEE Std 1588 ™ — 2008 or IEC-61588: 2009, IEEE C37.238-2017. The appropriate schemes have been developed for testing a domestic complex of the US-1588M and US-1588S devices with the use of PtpMon2 software. During the tests, it is envisaged to perform short-term and long-term measurements of time cha -racteristics of the synchronization signals generated at the output of US-1588S de-vice. The measurement results are presented as the Time Interval Error (TIE) and Maximum Time Interval Error (MTIE), which is calculated as a maximum value of the TIE array at a given measurement interval by using v1 of the PTPmon2 software. Also, we investigated the complex US-1588, which provides the transmission of accurate time stamps’ signals using the PTP protocol. According to the results of experimental studies, the obtained accuracy of time stamps transmission does not exceed 1 μs, which meets the requirements of the IEEE S37-238-2017 standard to the energy profile of PTP.
