IEEE FWCS PES/IAS Seminar: Advanced Distribution Protection & Control Applications

July 12 @ 9:00 am - 2:00 pm

In this seminar, several advanced protection and control applications will be explored targeted toward the distribution system. These include:

· High-Speed Falling Conductor Protection: Use of synchrophasors to detect the rapid change in a feeder conductor’s impedance when it breaks. The concept is to deenergize the feeder before the falling conductor contacts the ground. This prevents any arcing for fire mitigation and eliminates potential electrical shock hazard.

· High Impedance Fault Protection: Once a conductor breaks and contacts the ground, depending on the impedance, conventional overcurrent may or may not be able to detect the fault. For high impedance faults, the primary current may be very low (<10A primary). Precluding the use of conventional overcurrent protection. These types of faults may cause low amp level arcing with ground contact. This arcing may be examined, and by use of harmonics recognition and examining the randomness of the arcing, a high impedance fault may be declared.

– Microgrid P&C: Microgrids, depending on their assets and complexity, can employ a myriad of control implementations to optimize their operation. Microgrids can be employed for resiliency, reliability, energy arbitrage, peak shaving, and many other uses. The role of a secondary orchestration controller for the asset primary controllers will be examined. Depending on grid connected, grid isolated and transitioning operation, the protection requirements of the microgrid changes.
