- IEEE Standard 693 – Seismic Design
(9:00am – 12:15pm)
- In past large earthquakes, much of the damage to electric
power systems has occurred in substations, which are particularly
vulnerable due to the use of brittle, massive, and lightly-damped
components and equipment. IEEE 693, Recommended Practice for Seismic
Design of Substations, is the standard of choice for many electric
utilities in high earthquake hazard regions. This tutorial provides an
overview of the underlying principles, organization, and application of
IEEE 693. The Standard is unique in its comprehensive coverage of the
entire seismic qualification process for substation equipment,
including specific requirements for different types of equipment.
Engineers involved in the specification, procurement, evaluation, or
design of substation equipment and their supports for earthquake may
find this tutorial useful.
- Voltage Sourced Converters
(9:00am – 5:00pm)
- Voltage Sourced
Converters (VSCs), applied to high voltage ac transmission systems,
provide steady state and dynamic power flow control. They also
offer steady state and dynamic AC voltage and reactive power control.
Voltage Sourced Converters, as AC to DC and DC to AC converters,
exhibit the unique capability for fast control of real and reactive
power. These characteristics offer powerful means to improve
performance of electric power systems, both at the transmission and the
distribution level.
The tutorial, sponsored by Working Group I5
(Voltage Sourced Converter), is based on the Special Publication
08TP200 published in 2008. Several applications of Voltage
Sourced Converter such as STATCOM, UPFC, SSSC, VSC-HVDC in Power
Transmission and a comparison of various topologies currently used
are presented. Special requirements for DC
capacitors, valve assemblies, cooling systems, reactors, magnetic
interface, protective features and control modes of operations are
considered. This tutorial addresses safety measures, design and
production tests, equipment ratings, control and protection,
installation, maintenance, field commissioning, testing and operations.
