Unit Capability Validation, an Analytical Approach for MOD-25 Compliance

Unit Capability Validation, an Analytical Approach for MOD-25 Compliance

It is crucial to define the reactive power limits to evaluate the voltage support available under normal, abnormal and emergency operations with the unit's safe functioning. Published generator thermal capabilities curves, produced by the manufacturer, define the limits for safe operation based on the generator design's thermal limitations. Practically, the available reactive capability differs from the published equipment curves due to plant specific design and operating constraints. This presentation discusses a theoretical approach utilizing a simplified electrical distribution system and an ETAP model to identify and validate the plant-specific unit capability. 

Planning, Design, and Validation of a Microgrid using ETAP Digital Twin Platform

Planning, Design, and Validation of a Microgrid using ETAP Digital Twin Platform

The implementation of a Microgrid involve several stages, in which the engineer has to deal with the interaction of different processes and dynamics, taking into account the different modes, topologies and scenarios that the system could possibly have. This is the case of an ongoing project for an important Grid operator in Colombia, in which PTI S.A and OTI are working together to deliver a comprehensive Monitoring and Control system for an entire Microgrid, comprised of different energy resources as Diesel, Solar, Batteries and a connection to the Public Grid. Project stages involve Planning, Design, Validation, In site Deployment and Testings, and for that purposes, Etap PS/RT and Opal RT solutions will be used, on a Digital Twin Platform environment.

HV Arc Flash Studies for one of the Largest Utilities in South America

HV Arc Flash Studies for one of the Largest Utilities in South America

This presentation focuses on HV arc flash hazard analysis, as part of a multi-voltage AF study (115, 34.5, 13.8, and 0.22 kV) for one of the three largest utilities in South America with hydro and renewables generation and T&D. It demonstrates the versatility of the ETAP ArcFault™ to assist in the calculations and estimates of electric arc currents and incident energy level for HV substation equipment. The presentation discusses how ArcFault study results were used to select engineering and administrative control strategies, personal protective equipment (PPE), changes in protection schemes and adjustments to reduce electrical risks in operation & maintenance of electrical T&D systems.

AC Arc Flash using IEEE 1584 - University Campus Case Study

AC Arc Flash using IEEE 1584 - University Campus Case Study

Since the release of IEEE 1584-2018, the industry has been challenged to reach a consensus on applying the new standard. The most significant application “pain” so far has been identifying actual equipment data for input to the study, including bus gap and electrode configurations in the equipment. A case study of an arc flash analysis for a large university campus with MV and LV power distribution equipment of different types, vintages, and manufacturers is presented. The presentation highlights selection of electrode configuration(s) for various equipment types and voltage levels and correct application of arc current and enclosure size correction factors to significantly reduce the data entry time and effort. The presentation will cover upcoming IEEE P1584.1 revisions to apply IEEE 1584 for arc-flash hazard calculations directly from the revision subgroup chair.

Data Center Power System Expansion: DC Arc Flash Case Study

Data Center Power System Expansion: DC Arc Flash Case Study

Case study of a a power system study, which involved the replacement of an extensive UPS system at a data center. The studies included short-circuit, protective device coordination, and arc-flash hazard analysis for both the AC and DC systems consistent with the NFPA 70E 2018 and IEEE 1584 2018 Standards. The DC equipment as installed required mitigation efforts due to high incident energies. This presentation details the analysis, findings, and recommended mitigation for anyone embarking on similar retrofit or expansion studies.

Hyperloop Propulsion System from Design to Operate

Hyperloop Propulsion System from Design to Operate

HyperloopTT focuses on systems that moves people and goods safely, efficiently and sustainably; bringing airplane speeds to the ground by using passive levitation and electric linear propulsion in a low-pressure tube. This presentation discusses the complex power system challenges and collaboration with ETAP for conceptual design and detailed engineering of the 1st commercial prototype. The companies will then thereafter collaborate with ETAP and migrate the digital twin into operations to validate and improve the prototype design and extend to upcoming long-distance commercial & freight systems.

Sustainable Transportation - SCADA & Maintenance Planning

Sustainable Transportation - SCADA & Maintenance Planning

This case study for Mumbai Metro Rail covers Operator Training Simulator (OTS), where the customer is specifically looking for a simulation environment to test their operations in a real-time environment for the following reasons: avoid errors, enhance communication & management of new crews, train inexperienced operators, certification and competency for operators, situational awareness & workload management. ETAP OTS helped Schneider Electric, India, to give the right solution for Metro Mumbai. ETAP OTS utilizes a model-driven power network that enables the customer to approve switching procedures, perform predictive simulations to verify correct switching actions with software-in-the-loop, replicate real-world situations with unlimited scenarios for knowledge transfer via a trainer-to-trainees learning environment.
