Ground Grid Design with ETAP in a Steel Plant in Mexico  - EPSOL

Ground Grid Design with ETAP in a Steel Plant in Mexico - EPSOL

A Ground Grid design project is presented in a steel plant in Mexico and the objective is to reduce the step and touch potentials in the area of ​​electric arc furnaces of 50 kA connected to transformers of 13.8/0.6 KV and that in the moment of melting, they create dangerous currents for the workers who operate these furnaces. The project is executed from the field measurements of the resistivity of the ground and the design of the ground grid with the ETAP finite element method (FEM) and the construction of the grid is executed up to the foot of the ovens, thereby reducing said potentials to safe values ​​for the workers, contributing to a safer work area.

Online Monitoring of Nuclear Power Plant Auxiliary Power Systems using ETAP Real-Time

Online Monitoring of Nuclear Power Plant Auxiliary Power Systems using ETAP Real-Time

At a given nuclear power plant, nuclear safety is directly dependent on a reliable source of electric power supplied via the plant’s auxiliary power system.  The auxiliary power system typically consists of an MV and LV AC and a DC distribution system, powering thousands of individual loads and circuits, i.e., pumps, fans, valves, sensors, and controls specifically designed to protect the integrity of the nuclear reactor and containment structures.  This presentation will explore past practices and recent developments in the online monitoring of such systems using a digital twin. The presentation includes the reasons for utilizing online monitoring, the advantages of using a digital twin versus simple data collection, and the multi-faceted benefits realized from such a system (i.e., business, safety, reliability).

Industrial Plant Electrical Risk Management Program

Industrial Plant Electrical Risk Management Program

The Electrical Risk Management (ERM) group at FTI uses ETAP to provide short circuit, coordination, and arc flash studies as a part of building a safety program for industrial facilities around the US and Canada. This presentation will describe our approach to an overall safety program and the ways that a safety program encompasses more that just an engineering study. Some topics to be discussed are the need for maintenance personnel to understand the labeling, assessing the risk vs. just looking at the label, the choice between full coordination and arc flash hazard, field verification, and bolted fault current vs arcing fault current as it relates to equipment evaluation. We will look at the ETAP model of one of our industrial customers and discuss the benefits of using ETAP for our studies – reliability, adaptability to many systems by using configurations and scenarios, wizards, availability of DC and MV calculations, Star TCCs, ease of exporting reports to Excel, and solar and wind sources capability.

How to dynamically model & analyze generator stability during step loading using ETAP software

How to dynamically model & analyze generator stability during step loading using ETAP software

This study simulates the impact of step loading on the transient stability of a 2 x 25 MW GTG-based captive power plant at one of the Chemical Fertilizer Plants located at Trombay, India. The variation of electrical frequency and terminal voltage of the generator during the most conservative step loading of one generator unit is studied. The loads divided in steps are switched at certain time intervals to determine whether the frequency profile of the system is within the acceptable limit of ±5%. Load Flow and Short Circuit Studies are performed on the entire power plant distribution network of the fertilizer plant in advance to check the adequacy of equipment ratings during normal and short circuit conditions with all verified input data. The step load response study is carried out with only one GTG unit running in isolation, feeding only the critical emergency loads. Transient behavior of the GTG unit is simulated with IEEE transfer function dynamic models, viz. AC8B model of excitation system (AVR) and IEEE GGOV1 model for turbine governing system using the in-built standard library in ETAP software version 16.1.0. Various parameters of the generator like speed, active and reactive power, bus voltage, and frequency are plotted for determining the transient performance of the GTG unit.
