• 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. 
• Application Guidelines for Turn-Key Projects                  (9:00am – 10:15am)
• Uprating and Upgrading Existing Equipment                    (10:30am – 12:15pm)
• Responsible Use of SF6                                    (1:45pm – 3:15pm)
• Circuit Configuration Optimization                                  (3:30pm – 5:00pm)
• CIGRE Joint Working Group JWG B3/C1/C2.14 was established to investigate the influence of new development switchgear components on the circuit configuration of high voltage substations. 
• Approach of assessment of circuit configuration
• Classical circuit configurations and their assessment
• Alternative applications of configurations
• Results
• Additional aspects
