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. Read more

Remedial Action Scheme for Integrated G-T-D System

Remedial Action Scheme for Integrated G-T-D System

Due to system shutdowns stemming from drastic frequency decline associated with the loss of relatively large generating units, Fortis TCI embarked on exploring opportunities to curtail these events to improve system response. This was achieved through detailed modeling and validation of system parameters with event data gathered from previous events.  Carefully implemented Remedial Action Schemes are currently explored to provide cost-saving benefits; significantly improving frequency response, without the need for larger spinning reserves and minimize investment costs for BESS.

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

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. 

Microgrid Design & Analysis

Microgrid Design & Analysis

Microgrid Analysis & Design is an essential step for Microgrid Implementation. Upfront design and analysis of the target microgrid system, whether for brownfield or green-field Microgrid implementation, can help drive both technical and financial benefits, including determining optimized generation assets required to meet the microgrid objectives as well as a projection of return on investments. Analysis & design from safety, reliability, and financial perspective are critical for successful microgrid implementation to minimize the impact and rework during the installation phase. This presentation will provide recommendations on best practices for Microgrid Analysis & Design.

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.
