On demand webinars

Volt-VAr optimization (VVO)

Presented by: Christopher Pierce
As utilities look to operate the grid more efficiently, VVO provides major benefits for system performance, peak demand reduction, and reduction of losses. To optimize power, the VVO application is configured to automatically operate capacitor banks, voltage regulators, and/or transformer LTCs on the system. Optimization is achieved by configuring the VVO application with specific "rules" or parameters which define how the system devices should be operated by "flattening" the load profile and reducing the system voltage within ANSI standard C84.1 defined terms and conditions. This allows the utility to continuously optimize power deliver without requiring (or affecting) customer service. This seminar will provide an overview of VVO benefits, VVO concepts and explain how VVO systems are implemented.

Advantages of the digital substation

Presented by: Mahesh Sathe
The power of modern IEDs and Ethernet based substation automation systems not only shortens manufacturing, engineering and testing time for protection and control solutions, but also delivers space reduction when compared to traditional architectures. We will illustrate how a functionally equivalent system that uses smart devices and communications reduces the foot print for Drop-in control houses (DPCHs). Typical examples will be discussed for large, medium and small sized DPCHs, covering T&D utility, renewable energy and industrial applications. The advantages of reduced foot print will also be explored.

Accelerating IED refurbishments in cost and risk constrained businesses

Presented by: Joe Xavier
For an industry accustomed to the status quo, realizing the Smart Grid will be challenging. Fortunately the Protection and Control disciplines have responded with new platforms that provide the foundations to a Smart Grid - provided they are in service. Replacing an installed base of aging protection relays presents many challenges and viable solutions must support the Smart Grid goals and eliminate risks associated with IED refurbishment. This paper will examine the challenges of accelerated relay refurbishment programs and mitigating features to expect from next generation automation systems.

Coordination of fuses, circuit breakers, reclosers and sectionalizers will also be reviewed.

Line differential protection fundamentals

Presented by: Roger Hedding
As the use of fiber communication channels increases, line differential relaying is becoming a popular choice for line protection. 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.

Bus protection fundamentals

Presented by: Jack Chang
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.

Fault analysis using symmetrical components

Presented by: Michael Fleck
This webinar will present examples and applications from the Symmetrical Components general overview webinar. It will expand on the basics of symmetrical components and illustrate the benefits of breaking the system up phase components up into sequence components through example problems. We will investigate the sequence quantities that are present in different types of faults and use this information to analyze waveforms from actual fault waveforms.

Input sources for protective relays

Presented by: Elmo Price
A Relay is only as good as the analog input information it has to work with. Therefore, 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, as well as non conventional instrument transformers such as optical current transformers and Rogowski coils. Other issues such as transient response, and stray flux will also be discussed.

Generator protection fundamentals

Presented by: Mike Kockott
Generator protection schemes are unique in many ways, and usually involve many breakers and auxiliary equipment, increasing complexity. This webinar will address the basics of generator protection principles and the dynamics of synchronous generators. Typical faults and abnormal conditions will also be discussed.

Introduction to communication architectures in a substation environment

Presented by: James Bougie
For many years, many communications systems have been used in substations for protection, SCADA and enterprise solutions. Both protection and communication engineers need to have a good understanding of the various hardware channels and the different types of protocols used to maintain these systems and to develop new schemes. In today's substation, it is also essential to have a good understanding of the communications systems as these systems can significantly affect the performance of the substation. We will cover the various hardware systems and protocols used for the many applications within the substation environment.

Introduction to protection and control

Presented by: Roger Hedding
This webinar will define power system protective relaying and its purpose.

This webinar will discuss in detail the application of the IEC 61850 process bus for protection and control applications.

Symmetrical components general overview

Presented by: Michael Fleck
Symmetrical components have long been a mathematical means for Protection Engineers to analyze and interpret systems under abnormal conditions. In fact, Protection Engineers have long referred to symmetrical components as the language that defines the interconnected system. Sequence networks were more frequently constructed and equivalized by hand before the advent of personal computing; however, even with the help of a PC it is just important to understand the theory to provide sanity checks as well as analysis in unusual system configurations where modeling software can be cumbersome. This webinar will introduce Symmetrical components. We will investigate how positive, negative, and zero sequence quantities can be calculated from system phase quantities.

Transformer protection fundamentals

Presented by: Mike Kockott
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.

Using IEC 61850 for advanced reliable feeder automation

Presented by: Bryan Shannon
Several key applications of distribution feeder automation will be dicussed including high speed automatic bus transfer and bus blocking using GOOSE messaging. Both applications can greatly improve feeder reliability and minimize wiring between IEDs and commissioning time of automation schemes. Protection relays that natively support IEC61850 allow the user to unleash the full potential of the new standard for interoperability and do not force the user to the use of one exclusive relay manufacturer.

Wireless communication fundamentals

Presented by: Adam Guglielmo
Utilities are recognizing the strategic role of communications as they implement their smart grid plans. While in the past, utilities, and siloed organizations within those utilities chose proprietary narrowband networks for each application, this approach to communications is no longer practical. Borrowing from the enterprise model, utilities are now finding that in most cases it makes more sense to leverage a single high-performance communications infrastructure that can scale and be securely shared by multiple applications. Yet this does not mean we can simply ignore the requirements of individual utility applications such as feeder protection and automation. In this session, we will examine how today’s wireless solutions are meeting the overall requirements of utilities, look at how different wireless technologies compare with regard to specific applications, and suggest considerations utilities should keep in mind as they make their communications choices.
