Use Case 1 - Island Protection Implementation

Challenge: A customer needs to detect an islanding condition and identify events in the grid that could affect the point of interconnection (POI).

Value Added Proposition: Determine the parameters and methodology to trigger islanded identification. RTDS tests for validation purposes for loss of generation detection through sudden or cascade loss, loss of load detection through sudden or cascade loss, and trip to island from the external grid.

Benefits: Allow plant operation during islanding conditions through balance of load and generation.

Electrical processes are becoming more critical every day. Whether these processes are industrial or commercial, uninterrupted power supply is vital. In order to provide more reliable power supply, the power system can alternate sources to different bus bars. An Automatic Transfer Scheme (ATS) is the process of transferring the load of a busbar to another to ensure process continuity.

The ATS helps ensure the continuity of critical processes whose shutdown would result in unwanted economic and safety consequences. Transferring motor buses are specifically challenging due to the inertia forces and transients that exist in motors.

The Automatic Transfer and Restoration Scheme combines distributed protection, control, and ATS capabilities in a cost-effective package. Depending on your project-specific requirements for inputs/outputs, it can be performed on our SR850, F650, or P40x relays.

The transition to digital substations has emerged as a transformative approach to enhance operational efficiency, flexibility, and reliability. Digital substation standardization is a critical process that defines consistent protocols, interfaces, and architectures for the seamless integration of intelligent electronic devices (IEDs), communication systems, and control infrastructure. Digital substation standardization is essential for driving the adoption and implementation of advanced technologies in power system networks.

Challenge: Assure a new standard for digital substation design and provide new communications networks and architecture on digital substations.

Value Added Proposition: Design and implementation of standardized schematics for network architecture and communication signals exchange. .scd and .cid template file generation.

Benefits: A standardized solution for three typical topologies, making them more efficient on digital substation implementation. Closure of technology gap for customer employees.

Remedial Action Schemes (RAS) are a type of Wide-Area Protection Scheme, also known as Special Protection System (SPS) or System Integrity Protection Scheme (SIPS). RAS systems can detect disturbances in one part of an interconnected network that could result in interconnection overloading, under/over frequency conditions, and under/ overvoltage scenarios, and remediates these situations using pre-defined protection and control actions.

• Automatically disconnect generators or the load in the event of an unexpected loss of service of a transmission line to prevent system overloads.
• Improve system reliability by preventing power system outages.
• Increase transmission capability when building a new transmission line is not possible.
• Meet system operator mandates or system requirements.
