Download or read book Investigation of Wireless LAN for IEC 61850 Based Smart Distribution Substations written by Palak P. Parikh and published by . This book was released on 2012 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: The IEC 61850 standard is receiving acceptance worldwide to deploy Ethernet Local Area Networks (LANs) for electrical substations in a smart grid environment. With the recent growth in wireless communication technologies, wireless Ethernet or Wireless LAN (WLAN), standardized in IEEE 802.11, is gaining interest in the power industry for substation automation applications, especially at the distribution level. Low Voltage (LV) / Medium Voltage (MV) distribution substations have comparatively low time-critical performance requirements. At the same time, expensive but high data-rate fiber-based Ethernet networks may not be a feasible solution for the MV/LV distribution network. Extensive work is carried out to assess wireless LAN technologies for various IEC 61850 based smart distribution substation applications: control and monitoring; automation and metering; and over-current protection. First, the investigation of wireless LANs for various smart distribution substation applications was initiated with radio noise-level measurements in total five (27.6 and 13.8 kV) substations owned by London Hydro and Hydro One in London, ON, Canada. The measured noise level from a spectrum analyzer was modeled using the Probability Distribution Function (PDF) tool in MATLAB, and parameters for these models in the 2.4 GHz band and 5.8 GHz band were obtained. Further, this measured noise models were used to simulate substation environment in OPNET (the industry-trusted communication networking simulation) tool. In addition, the efforts for developing dynamic models of WLAN-enabled IEC 61850 devices were initiated using Proto-C programming in OPNET tool. The IEC 61850 based devices, such as Protection and Control (P & C) Intelligent Electronic Devices (IEDs) and Merging Unit (MU) were developed based on the OSI-7 layer stack proposed in IEC 61850. The performance of various smart distribution substation applications was assessed in terms of average and maximum message transfer delays and throughput. The work was extended by developing hardware prototypes of WLAN enabled IEC 61850 devices in the R & D laboratory at University of Western Ontario, Canada. P & C IED, MU, Processing IED, and Echo IED were developed using industrial embedded computers over the QNX Real Time Operating System (RTOS) platform. The functions were developed using hard real-time multithreads, timers, and so on to communicate IEC 61850 application messages for analyzing WLAN performance in terms of Round Trip Time (RTT) and throughput. The laboratory was set up with WLAN-enabled IEC 61850 devices, a commercially available WLAN Access Point (AP), noise sources, and spectrum and network analyzers. Performance of various smart distribution substation applications is examined within the developed laboratory. Finally, the performance evaluation was carried out in real-world field testing at 13.8 and 27.6 kV distribution substations, by installing the devices in substation control room and switchyard. The RTT of IEC 61850 based messages and operating time of the overcurrent protection using WLAN based communication network were evaluated in the harsh environment of actual distribution substations. The important findings from the exhaustive investigation were discussed throughout this work.

Download or read book Network and System Management Using IEC 62351 7 in IEC 61850 Substations written by Chantale Robillard and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Substations are a prime target for threat agents aiming to disrupt the power grid's operation. With the advent of the smart grid, the power infrastructure is increasingly being coupled with an Information and Communication Technologies (ICT) infrastructure needed to manage it, exposing it to potential cyberattacks. In order to secure the smart grid, the IEC 62351 specifies how to provide cybersecurity to such an environment. Among its specifications, IEC 62351-7 states to use Network and System Management (NSM) to monitor and manage the operation of power systems. In this research, we aim to design, implement, and study NSM in a digital substation as per the specifications of IEC 62351-7. The substation is one that conforms to the IEC 61850 standard, which defines how to design a substation leveraging ICT. Our contributions are as follows. We contribute to the design and implementation of NSM in a smart grid security co-simulation testbed. We design a methodology to elaborate cyberattacks targeting IEC 61850 substations specifically. We elaborate detection algorithms that leverage the NSM Data Objects (NSM DOs) of IEC 62351- 7 to detect the attacks designed using our method. We validate these experimentally using our testbed. From this work, we can provide an initial assessment of NSM within the context of digital substations.

Download or read book Delay Performance Evaluation of the IEC 61850 Standard in Power Transmission Substations written by Salman Safdar and published by . This book was released on 2015 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Substations are a crucial element at the transmission and distribution level of electric power systems. The primary substation equipment (power transformers and high voltage switching equipment) is used to transfer and transform electric energy by stepping up or down the voltage in transmission substations. Secondary equipment (such as IEDs, Intelligent Electronic Devices) is used to control, protect and monitor primary equipment and the rest of the substation while relying on a variety of communication protocols. The IEC 61850 standard is a viable candidate for current Substation Automation Systems (SAS) as well as for future Smart Grid (SG) substations. SG is the next generation power grid, which aims to improve reliability and efficiency, reduce the cost of electric energy, and minimize environmental impacts. SG will be relying on effective and reliable communication, and the IEC 61850 standard shows the potential for providing such a communications framework. Currently, the delay performance evaluation of this standard has been carried out at the distribution level. At the transmission level, where data rates are high and there is a low latency requirement, this standard has yet to show its performance. In future Smart Grids, transmission substations will be part of a self-healing network that identifies the faults/blackouts and automatically connects/disconnects the feeders and re-routes power to ensure security of the grid. According to IEC 61850, the communication requirements for transmission substations will be more time-critical. In this work, the IEC 61850's delay performance is evaluated at a transmission substation between different bays in the case of one outgoing feeder's failure. OPNET software is used as a simulation tool. In OPNET, devices such as Analog Merging Units (MUs) and IEDs were implemented according to the IEC 61850 standard. Delay performance for Generic Object Oriented Substation Events (GOOSE) messages is evaluated in terms of End-to-End (ETE) GOOSE message delay, with/without Virtual Local Area Network (VLAN) attributes according to IEEE 802.1Q and with/without Quality of Service (QoS) attributes according to IEEE 802.1p.

Download or read book Wireless Communications for Power Substations RF Characterization and Modeling written by Basile L. Agba and published by Springer. This book was released on 2018-06-08 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book consists of the identification, characterization, and modeling of electromagnetic interferences in substations for the deployment of wireless sensor networks. The authors present in chapter 3 the measurement setup to record sequences of impulsive noise samples in the ISM band of interest. The setup can measure substation impulsive noise, in wide band, with enough samples per time window and enough precision to allow a statistical study of the noise. During the measurement campaign, the authors recorded around 120 noise sequences in different substations and for four ranges of equipment voltage, which are 25 kV, 230 kV, 315 kV and 735 kV. A characterization process is proposed, by which physical characteristics of partial discharge can be measured in terms of first- and second-order statistics. From the measurement campaign, the authors infer the characteristics of substation impulsive noise as a function of the substation equipment voltage, and can provide representative parameters for the four voltage ranges and for several existing impulsive noise models. The authors investigate in chapters 4 and 5 the modeling of electromagnetic interferences caused by partial discharge sources. First, the authors propose a complete and coherent approach model that links physical characteristics of high-voltage installations to the induced radio-interference spectra of partial discharge sources. The goodness-of-fit of the proposed physical model has been measured based on some interesting statistical metrics. This allows one to assess the effectiveness of the authors' approach in terms of first- and second-order statistics. Chapter 6 proposes a model based on statistical approach. Indeed, substation impulsive noise is composed of correlated impulses, which would require models with memory in order to replicate a similar correlation. Among different models, we have configured a Partitioned Markov Chain (PMC) with 19 states (one state for the background noise and 18 states for the impulse); this Markov-Gaussian model is able to generate impulsive noise with correlated impulse samples. The correlation is observable on the impulse duration and the power spectrum of the impulses. Our PMC model provides characteristics that are more similar to the characteristics of substation impulsive noise in comparison with other models, in terms of time and frequency response, as well as Probability Density Functions (PDF). Although PMC represents reliably substation impulsive noise, the model remains complex in terms of parameter estimation due to a large number of Markov states, which can be an obstacle for future wireless system design. In order to simplify the model, the authors decrease the number of states to 7 by assigning one state to the background noise and 6 states to the impulse and we call this model PMC-6. PMC-6 can generate realistic impulses and can be easily implemented in a receiver in order to mitigate substation impulsive noise. Representative parameters are provided in order to replicate substation impulsive noise for different voltage ranges (25-735 kV). Chapter 7, a generalized radio-noise model for substations is proposed, in which there are many discharges sources that are randomly distributed over space and time according to the Poisson field of interferers approach. This allows for the identification of some interesting statistical properties of moments, cumulants and probability distributions. These can, in turn, be utilized in signal processing algorithms for rapid partial discharge's identification, localization, and impulsive noise mitigation techniques in wireless communications in substations. The primary audience for this book is the electrical and power engineering industry, electricity providers and companies who are interested in substation automation systems using wireless communication technologies for smart grid applications. Researchers, engineers and students studying and working in wireless communication will also want to buy this book as a reference.
