- Sub-Harmonic Protection Relays - Setting the relay for operation
We'll discuss an engineering process that can be followed for the application of a new sub-synchronous relay that provides protection for transmission lines, particularly those with serial compensation and wind farm interconnections, and how it can be used to monitor the power system to determine the existence of sub-synchronous resonance phenomenon. We also discuss possible settings for the sub-harmonic protection relay, including the protection elements associated to sub-harmonics as well as providing overcurrent and other protection functions. Learn how to use software tools that determine the levels of sub-harmonics and how to use the values for relay settings. We will also demonstrate how the relay responds when injected with oscillography files that contain sub-harmonics.
- Digital Fault Recording - Understanding today's advanced DFRs
Proper interpretation of fault and disturbance data is critical for the reliability and continuous operation of the power system. A correct interpretation gives valuable insight into the conditions and performance of various power system protective equipment. Analyzing records is not an intuitive process; it requires system protection knowledge and experience. Having an understanding of the fundamental guidelines for the event analysis process is imperative for new power engineers to properly evaluate faults. As senior power engineers retire, knowledge of how to decipher fault records could be lost with them. We'll explore various aspects of power system fault analysis and provides the new event analyst with a basic foundation of the requirements and steps to analyze and interpret fault disturbances.
