Working Group Meetings (Documentation) IEEE PES General Meeting (JTCM 2017) July 16-20, 2017,  Chicago, Illinois, USA IEEE PES Substations Committee Meeting (JTCM 2017) May 7-11, 2017,  Richmond, VA, USA IEEE PES General Meeting (JTCM 2017) July 16-20, 2017,  Chicago, Illinois, USA Working Group Activities Liason DC & FACTS Subcommittee Standards Std 1031, IEEE Guide for the Functional Specification of Transmission Static Var Compensators This guide documents an approach to preparing a specification for a transmission static var compensator. The document is intended to serve as a base specification with an informative annex provided to allow users to modify or develop specific clauses to meet a particular application.   Std 1303, IEEE Guide for Static Var Compensator Field Tests General guidelines and criteria for the field testing of static var compensators (SVCs), before they are placed in-service, for the purpose of verifying their specified perforamance are described. The major elements of a commissioning program are identified so that the user can formulate a specific plan that is most suited for his or her own SVC. Taskforces TF1 – Step Response Review of IEEE1031-2011, section 8.2.2 and B.5.2.2 Definitions - Overshoot and rise time unclear for cases including TSC and/or MSC switching Add typical parameter values for rise time, overshoot and settling time Add guidance for step response studies, specifically regarding the impact of using an equivalent system model instead of a Thevenin equivalent Discussion of step response for solutions including TSC(s) and MSC(s) Deliverables to include a position paper and addendum to IEEE1031  TF2 – Harmonics Review of IEEE1031-2011, Annex B 5.3 Harmonic Performance Background/ambient harmonic measurements Harmonic network impedance modelling Impact of background/ambient harmonics and harmonic network impedances on design for SVC design and Hybrid STATCOM Deliverables to include a position paper and/or addendum to 1031 Reliability Survey WG I4 has maintained a list of industrial and utility SVC installations around the world, and is currently collecting information from SVC owners/users on the availability and reliability of existing SVC installations to quantify the number and causes for SVC outages. The intention of this survey is that it will act as information to owners and those specifying new installations, about the main causes of unavailability of SVCs.
