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.

Efficient Design & Analysis with CoSimulation

Efficient Design & Analysis with CoSimulation

Co-simulation is the cooperative simulation of a system model through different software packages. Collaborative simulation, as such, spans more physics domains and offers more insight than single-domain engines alone. Therefore, the collective composition of its parts enables multi-domain, multi-physics simulation results.​ETAP CoSim™ enables ETAP simulation engines to collaborate and interact. For example, the ETAP Time Domain Power Flow can co-simulate with ETAP Harmonic Analysis to assess harmonics distortion over time. ETAP CoSim platform also enables ETAP and 3rd party tools to co-simulate and solve large, complex, and multi-disciplinary system models—collectively via an efficient API surface. The ability to co-simulate with third-party software extends existing software capabilities into the multi-physics domain and greater situational awareness. This solution presentation will introduce the concepts of co-simulation and the flexible ETAP CoSim platform. The presentation will also highlight commercial use-cases of Phasor and Electromagnetic co-simulation using emtCoSim™ and Controller Hardware-in-the-Loop (CHIL).

Integrated Stability & Protection Sequence of Operation

Integrated Stability & Protection Sequence of Operation

Many protection functions such as over/under frequency, out-of-step, generator loss of excitation are set based on power system dynamic characteristics. These protection functions were conventionally set with the assumption that, system dynamics are predictable using simplistic and aggregated models. Higher penetration of distributed energy resources (DERs) has made power system dynamics considerably more complex to predict through conventional approaches. ETAP offers a new solution to perform unified protection and transient stability study to accurately capture interactions between system dynamics and protection system. This solution allows protection engineers and network planners to 1- tune protection settings to act properly during system dynamics, 2- design and test remedial protection schemes, 3- evaluate all protection functions such as out-of-step, overcurrent and generator loss of excitation protection function and 4- perform grid code studies that require evaluating DER performance along with its protection system.

GIS Modeling & DNA

GIS Modeling & DNA

The traditional power system model and desktop-based analysis work well for greenfield projects. It becomes incredibly challenging to make use of the modeling in a brownfield project. The network routes are limited by existing infrastructure and road layouts. A new design for a built-up urban area is possible by multiple iterations of cable lengths, optimal routes, placement of electrical assets, etc. The iterative process becomes more manageable by having a georeferenced map of all interest areas with high accuracy. GIS-based software becomes extremely helpful to undertake a brownfield design. However, the challenge remains in extracting the GIS data into a power system software in executing the electrical analysis. ETAP is breaking ground in this avenue. EnergyTron is closely working to implement this on a large scale, potentially the largest in the world for this type of project analysis.

Enterprise Asset Management & Automated Fault Analysis

Enterprise Asset Management & Automated Fault Analysis

Solution introduction & case study presentation. Remote Management of Protection Relays  - Improved Productivity & Compliance Benefits. This presentation aims to define and demonstrate the importance of the remote management of protection relays in large power system networks. A protection system is vital for network security and reliability. A centralized system should aim to get each protection relay setting, records, logic, and status quickly and efficiently so that all these data can be analyzed, managed, and utilized. In OETC grid stations, there are more than 4000 protection relays installed.  OETC network is rapidly expanding every year. There are incidences of tripping due to various reasons. These isolated equipment restorations can be done faster if protection relays fault records, events retrieved through remote access. ETAP and OETC are jointly working on conceptualizing and implementing a fully functional system for remote relay access and data retrieval – eProtect. This presentation discusses the technical requirements, networking solutions, cybersecurity requirements, features, testing, validating system requirements, and detailed benefits. Challenges faced during implementation will be discussed together with their resolution.

Enhanced End-to-End Real-Time SILHIL Workflows with ETAP and ePHASORSIM

The ETAP/ePHASORSIM hybrid power system solution is ideally suited for installing and certifying any new device on the grid for protection, monitoring and control, thus reducing risk and costly commissioning time—as well as validation of reliability and security of any transmission, distribution and generation grid before implementation. Users can simulate SIL and HIL scenarios in real time, greatly reducing time-to-market. We will demonstrate the time-savings and value of this solution by exporting an ETAP model to ePHASORsim and controlling it in closed-loop with ETAP’s controller hardware.  To fine-tune the response, we will change the ETAP model, export again, the re-start the simulation—a cycle commonly observed in testing environments.
