Strengthen protection system performance, flexibility, and operation

Managing Complexity to ensure Grid Resilience

"It’s no secret - the power grid is rapidly changing with the introduction of renewables, electromobility, and emerging eco-friendly technologies. The grid infrastructure continues to operate closer to its physical limits while commonly experiencing sudden dynamic phenomena requiring quick action. All the while power grid operators are facing an almost impossible task to ensure grid resilience. Amidst the energy transition, the Grid Resilience portfolio enables operators to strengthen system-wide protection, monitoring and control to increase grid performance and respond rapidly to scenarios that threaten the grid’s stability."

Improve performance of equipment protection throughout the entire lifecycle

Planning

Automate the design and coordination of the protection system and improve data accuracy.

Transmission and Distribution protection engineers need to accurately design and coordinate protection systems and ensure relay settings are calculated for optimal performance. This process can be simplified by leveraging tools to automate this process, resulting in significant time savings and improved accuracy, and reduction in human errors.  

Configuration

Configuring protection devices accurately requires a detailed relay model and interoperability with relay configuration tools.

The protection devices will only perform as good as the calculation results, entered during the Configuration phase (with the respective vendors’ relay configuration tools), are accurate. Leveraging tools that provide highly accurate relay models and interoperability with respective tools can result in significant time savings, and accuracy. 

Maintenance

Optimize device maintenance with a “Digital Twin” of the protection system.

Traditionally, protection and control devices were installed and rarely required changes or updates to ensure grid stability. As the grid is becoming more adaptable – transparency and flexibility are required to execute the proper maintenance of these assets. With the Grid Resilience portfolio, utilities can keep a central database of accurate and up-to-date protection data with powerful interfaces – enabling frequent updates, and a log of changes in devices. This serves as a “Digital Twin” of the protection system and provides the visibility to optimize data quality and grid reliability. 

Operation

Achieve grid stability and gain visibility into the operation of your protection system with powerful simulation, analysis, and assessment tools.

Achieving a sound protection system performance in any situation that arises is crucial for a stable continuous operation of the power grid. Applications using modern analytics and powerful simulation capabilities can provide grid operators and protection engineers involved on request with in-depth insights into nature, causes and details of protection trip events in close-to-real time and frequently revalidate the accuracy of the protection system during changing operational conditions.

Monitoring

Increase stability and reliability of system operation with a wide-area monitoring system (WAMS).

The growing complexity of the grid is driving operators to face new threatening situations requiring rapid reactions to maintain stability. The implementation of a Wide-Area Monitoring System based on Phasor Measurement Units (PMUs) allows the active grid operations engineer to gain better visibility into the system (events, trends, fluctuations, etc.), quickly appraise the current system situation, and react in a timely manner to prevent cascading blackouts.

Wide-Area Protection

Efficiently remedy observed instabilities by automatically initiating a respective tripping signal to the field.

When the monitoring system detects a clear violation of the limitations in phase angle differences (such as an overloaded line or a power swing), predefined protection actions can be calculated on a central level. Wide-Area Protection can remedy the observed instability faster by automatically initiating a respective tripping signal to the field. By avoiding human interaction, this process allows for a more immediate, efficient, effective and error-prone mitigation of the observed instability.. 

Situational Awareness and Operator Assistance

Gain further visibility into the grid and make critical decisions with confidence.

To maintain grid stability, system operators need to expand their situational awareness in the control room, and leverage tools to support them in making critical decisions during stability problems. A higher share of inverter-based renewables and less inertia in the system entails that dynamic limits may be reached earlier than thermal limits. This approach consists of a model-based security analysis. A state estimator snapshot from the SCADA/EMS system triggers a real-time grid simulation. To provide confidence in difficult situations, grid operators can simulate what-if scenarios based on real-time data before executing switching actions. Optionally, the system can instantaneously investigate and actively propose suitable actions to the operator.

Grid Planning based on Real-Life Operating Scenarios

Increase reliability of network extension decisions by simulating the grid based on real-life scenarios.

Bringing together grid control and planning, a simulation-based Dynamic Stability Assessment enables the grid planners to run simulations based on real-life scenarios. Planners can make more reliable investment decisions to enhance the network with a techno-economic comparison of network extension alternatives based on (slightly modified) real-time snapshots and real-life scenarios.
