D29 | Tutorial on Setting Impedance-Based Power Swing Blocking and Out-Of-Step Tripping Functions on Transmission Lines | Kevin Jones | Normann Fischer | Create a tutorial on setting impedance-based power swing blocking and out-of-step tripping functions related to transmission line applications. Specific relay settings examples will be provided. Other methods of detecting out-of-step conditions that exist will be summarized and referenced, but will not be discussed in detail. |
D30 | Tutorial on Application and Setting of Ground Distance Elements on Transmission Lines | Karl Zimmerman | Ted Warren | Write a tutorial on factors affecting the application and setting of ground mho and quadrilateral distance elements on transmission lines. |
D34 | Coordinate with IEC 60255-187-3 Functional Specification for Line Current Differential | Normann Fischer | TBD | Coordinate with IEC 60255-187-3 (functional specification on line current differential requirements) and provide feedback. |
D35 | Evaluation of Transmission Line Pilot Protection Schemes | Rick Gamble | Brandon Lewey | Prepare a technical report to the line protection subcommittee to evaluate advantages and disadvantages of common transmission line pilot protection schemes, including POTT, DCB, DCUB, and line current differential. The schemes will be evaluated in terms of speed, sensitivity, dependability and security based on the design and configuration of transmission lines and system topology. A limited number of example systems will be evaluated. |
D37 | Impact of Series Compensation on Transmission Lines | Mike Kockott | Luis Polanco | Create a report the impact of series compensation on transmission lines. |
D38 | Impact of High SIR on Distance Relaying | Chris Walker | Greg Ryan | Investigate the need for a working group on the Impact of High SIR on Distance Relaying. |
