High-Voltage Arc Flash for Overhead Conductor Systems

High-Voltage Arc Flash for Overhead Conductor Systems

Arc flash analysis extends well beyond the scope of IEEE 1584 and NFPA 70E methodology for transmission, distribution and renewable energy systems. For many years, the industry has been lacking an “all-in-one” solution for performing arc flash analysis on DC, LV, MV and HV AC systems. ETAP ArcFault™ provides a validated method for performing arc fault simulations in T&D open-air overhead conductor systems plus it provides two methods to determine the incident energy for arc-flash in 3-phase enclosed equipment for 15 to 38 kV renewable energy collector systems. This presentation explains the background and methods for arc fault simulations and explains how ETAP ArcFault helps utilities comply with OSHA requirements to perform arc-flash analysis for systems voltage above 1.0 kV.

Phase to Phase Fault Debacle: Fault Lasted 1.7s/108 Cycles. Protection Studies are quite Challenging

Phase to Phase Fault Debacle: Fault Lasted 1.7s/108 Cycles. Protection Studies are quite Challenging

How a failure, to properly perform protection studies, led to a significant substation safety incident and outage. ​Understanding minimum and maximum fault current values are critical in this case study. The shortcomings led to a fault not being removed fast enough.  Short circuit impedances are very valuable, it is critical to have the right cables and impedances of the equipment. An excellent learning from this case study is that line to line arc flash fault exists much longer at medium voltage level. In low voltage we do not see those type of line-to-line arc flash faults because line to line arc flash fault will rapidly turn into a three-phase fault. The arc flash calculator is a great tool to estimate incident energy.  The arc flash calculator shows both methods:  below 15 kv we can use IEEE 1584-2018 to calculate incident energy at 15 Kv, and above our fault calculated method can calculate calories exposure during the fault.

Distribution Network Analysis

Distribution Network Analysis

Alpine Energy Case Study – Building a model for today and the uncertain tomorrow. To maximize the benefit from our ETAP models, we developed a system that makes use of the available features to provide structure to our system models, and allow flexibility to deal with future model expansion and changes. The foundation to achieving this objective was the establishment of a naming convention and model structure that would enable the loading of models and data handling processes to be done with ease. Further enhancing our use of ETAP, we make use of templates and color coding linked to the themes to match the real world network in the modelling world. Lastly, the library was built from scratch and has now matured to a stage where new data is phased in and updated during the validation of models. Following our investment in building our models, in order to maximize the benefit from our ETAP, we developed rigorous processes to ensure accuracy and consistency in building models and managing data. Once data is updated, we utilize ETAP to run Load Flow, Fault Level and Protection Coordination studies and rely on ETAP multi-dimensional database capabilities to set financial years, switching configurations and add new proposed loads to the relevant configuration year. Combining the above features and processes, we have established a disciplined and rigorous Network Development Planning process using ETAP. This has enabled us to plan for the future in an efficient and effective manner. Our ETAP models are benchmarked against actual power system conditions by collecting historical demand data (voltages and currents) from smart meters at customer level, power quality measurement devices at distribution transformers, protection relays at substations, and our SCADA system. But this is not the end, we have developed a future roadmap for our ETAP models with plans to fully integrate with our geospatial information system and our supervisory control and data acquisition (SCADA) environment, to utilize protection coordination, and build smart scenario wizards to do the hard work for us.
