Elipse Software

Power outages can cause huge financial losses, such as reprocessing production and losing raw materials. Traditional load shedding systems have high engineering, maintenance, and expansion costs due to their complex logic and huge number of topological states that need to be analyzed and evaluated.

Elipse’s Load Shedding module reduces interruption losses, thus increasing reliability and electric system’s availability while maintaining low engineering and maintenance costs.

Elipse Power Load Shedding is the perfect solution for keeping critical loads working continuously. Its groundbreaking architecture is based on dynamic algorithms that consider the plant’s electric model, thus resulting in a more robust system, with a rapid application deployment and less costs to expand.

Elipse Power Load Shedding algorithm evaluates scenarios that can potentially cause instability to the electric system, and by pre-selecting the load sets to be turned off in such events, the solution acts upon them in few milliseconds.

The module runs continuous simulations on each scenario, calculating which loads would be discarded in case an instability occurs. This helps to keep the protection system constantly informed on which breakers are to take action even before the destabilizing event occurs, thus making the time between detecting the problem and effectively turning off the loads as short as possible. With it, the system can recover quickly, finding a new point of stability.

Features

• Smart algorithm that runs continuous simulations of generation/supply loss scenarios: triggers dispatch relays only for the smallest amount of load required.
• Quick action response: does not compromise system stability.
• Considers the spinning reserve available in the generators for better use of industrial energy assets.
• Easiness and flexibility to define each load’s priority.
• Software solution based on IEC 61970 – CIM standard.
• Detection of disturbances due to generation loss, under-frequency trigger, or violation in security limits of generators’ load.

Benefits

• Greater operational security due to anticipated detection of risky situations.
• Reduced engineering, maintenance, and commissioning time for system implementation.
• Minimum shedding time guaranteed by pre activating relays and using GOOSE messages.
• More reliable system and more priority loads available.
• Fewer financial losses due to power supply interruptions.
• Fewer investments required in hardware.
• Agility and assertiveness when prioritizing the loads.
