    Benton Vandiver

    Introduction to protection & control

    July 27 @ 11 AM EST
    This webinar will define power system protective relaying and its purpose. A general overview of key concepts, protective relay classifications, operating principals, operating reliability and relaying philosophy will be presented. Also provided is a brief review of terminology, ANSI C37.2 device function numbers and IEC 61850 logical nodes (device function models).

    Input sources for protective relays

    August 18 @ 11 AM EST
    A Relay is only as good as the analog input information it has to work with. Having knowledge of the devices that provide the analog inputs to a relay is necessary. This webinar will explore analog conventional voltage and current instrument transformers. Other issues such as transient response, and stray flux will also be discussed.

    Bus protection fundamentals

    August 24 @ 11 AM EST
    Bus faults tend to be very robust, and therefore easy to detect. This robustness may cause current transformers to saturate in the event of close in external faults. Bus protection schemes must recognize current transformer saturation and restrain from operating for external faults while operating quickly for internal faults. This webinar will discuss the various schemes used for bus protection.

    Line protection fundamentals

    Sept 28 @ 11 AM
    This webinar will introduce the basic principles of line distance relaying. Topics like operating characteristics, fault loops, faulty phase identification and all the other basic principles utilized in a today's numerical relays will be discussed in detail. Communication assisted directional schemes will also be discussed.  The webinar will showcase all the applications that can be designed to protect the transmission line using these principles. In addition, this webinar will present the concept of line current differential relaying, and review scenarios where its application makes the protection scheme much simpler than distance protection pilot schemes.

    Generator protection fundamentals and solutions

    Sept 21 @ 11 AM
    Generator protection schemes are unique in many ways, and usually involve many breakers and auxiliary equipment, encompassing the entire generation unit. This webinar will address the basics of generator protection principles and the dynamics of synchronous generators. Protection and detection principles for typical generator faults and abnormal operating conditions will be discussed.  Advanced numerical measuring and signal processing technologies employed by modern IEDs have enabled other versatile and reliable generator unit monitoring and fault detection techniques.  They will also be shared in this webinar.

    Transformer protection fundamentals

    Oct 5 @ 11 AM
    This webinar will address the challenges of protecting transformers with digital relays. Fundamental theory regarding transformers, harmonic restraint, differential protection, and backup overcurrent protection will be discussed.

    Fundamentals of communication for protection

    Oct 24 @ 11 AM EST
    The webinar encourages protection engineers to learn enough about communications to be able to formulate protection-imposed requirements to communication engineers and work jointly on implementing these. Fundamental concepts of communications are discussed, including communication media (copper, fiber, wireless) and channel types (dedicated, multiplexed, switched). Multiple communication technologies used for protection applications and their characteristics are covered: Power Line Carrier (PLC), digital microwave, audio tone, spread spectrum radio, SONET/SDH, MPLS and Carrier Ethernet. The importance of ownership of protection-imposed communication requirements by protection engineers is emphasized as without involvement of protection engineers, reliability of the overall power system could be unnecessary compromised.

    Protection (distance & differential) over modern Packet Switched (wide area) Networks

    Nov 2 @ 11 AM EST
    Teleprotection, an electrical utility’s most critical application, poses challenging requirements,  especially when using Packet Switched Networks (PSNs). The performance of a power line protection system depends directly on the abilities of the communication network to transmit data fast, and reliably. The demanding requirements, that were fulfilled by TDM/SONET, need to be carefully reviewed when migrating to Packet Switched Networks (PSNs). Special measures are required to prevent incorrect operation or false tripping. In this webinar, the protection and telecommunication fields meet to guarantee the stringent channel performance required by distance and differential protection when coupled to innovative backbone PSNs with enhanced redundancy mechanisms, and strong monitoring capabilities.

    IEC61850 compliant Digital Substation – Advanced features and benefits

    Nov 16 @ 11 AM EST
    The digital substation portfolio encompasses state-of-the-art communication solutions, bay-level products, as well as process level equipment. Modern non-conventional-instrument-transformers with a digital interface increase safety and reduce footprint requirements, while stand-alone merging units open up a path to retrofits and upgrading existing substations and the ability to digitize information right at source, in the field. Building upon the international standard for communication networks and systems for power utility automation, IEC 61850The webinar will explain the main potential of this technology: increased safety, interoperability, ease of configuration, maximized reliability and availability, real-time performance, smart-grid communications capabilities and reduced cost of ownership. In the second half of the webinar an overview on advanced features related to simulation and testing is provided. Traditional substations require engineers to check wiring connectivity, voltage signals, control logic and other things using meters, etc.  With IEC61850 Edition 2 and digital substation these activities are  now handled by user friendly software tools such as ABBs IET600/ITT600.

    Wireless communication fundamentals

    Nov 30 @ 11 AM EST
    Electric distribution utilities are recognizing the strategic role of communications as they implement their grid modernization plans. In the past, utilities and siloed organizations within those utilities chose to implement separate low bandwidth, proprietary communication networks for each application. However, utilities are finding that this approach to communications is no longer practical. Borrowing from the enterprise model, utilities are finding that, in most cases, it makes more sense to leverage a single private, modern, high-performance communications infrastructure that can scale, be securely shared by multiple applications and user groups, and be tailored to the specific requirements of applications, connected apparatus, and service territory geography. In this session, we will examine how modern private wireless communication networks constructed using a mix of broadband mesh and PTP/PTMP, narrowband mesh and PTP/PTMP, and cellular technologies can meet the overall needs of utilities as well as the requirements of specific applications.
