    fast Load Shed
     

    Conventional frequency and voltage load shedding schemes operate typically between 250ms to seconds. Contingency-based load shedding schemes are typically faster at 160 – 400 ms, depending on both system architecture and communications employed. Both these scheme types are too slow for industrial cogeneration applications such as oil and gas or manufacturing, where very fast load shedding is required for power system and critical process integrity.

    End-to-end execution mode under 20ms
     
     
    Digital fault recorder summary with the latest information on the events, faults, transients and disturbances.
         
     
    Recording capability
     
    There are three recorders available within the C90Plus that eliminate the need for other stand-alone recording equipment. The transient recorder allows for a high sampling rate usually to capture power system faults and system transients. The disturbance recorder is used to capture longer records in order to understand issues such as voltage sags or swells. Lastly, the C90Plus is equipped with a powerful and accurate Sequence of Event (SOE) recorder. Information for all three recorders can be accessed either through the front panel HMI or through EnerVista™ Launchpad Software.
     
    Deterministic automation
     
    A power system is a real-time system in which time and accuracy of every control should be considered critical. C90Plus operating systems ensure that every action and control is scheduled properly and beforehand to guarantee that nothing is missed nor delayed. This intelligence inside the C90Plus handles both protection trip commands as well as any other logic written for execution as per its programmed timeline. No more delays or missed timelines when it comes to control because the processor is “busy” or otherwise.

    Access Control
    Multilin devices and relays are designed with simple but powerful security to enable reliability and compliance for virtually any project or implementation. With support for multi-level permissions and multi-factor supervisory controls, Multilin devices can help you manage the integrity of your system during commissioning, testing, implementation, and beyond. The UR and URPlus families provide separate authentication for settings and commands to the system. In addition, as discrete authentications for local and remote access they also provide supervisory control factor that can lock or unlock a device for configuration changes and other modifications.
     
    Intrusion Detection
    Multilin’s family of protection and control products can also help enable your security perimeter and intrusion detection programs. By providing essential alarming and logging of critical events, Multilin devices can help you detect potential breaches within your system and allow you to respond quickly and effectively. Specifically, unsuccessful access attempts are logged, alarmed, and lead to potential attackers being locked out. This ensures the reliability of your system during questionable activity, and a control factor that can lock or unlock a device for configuration changes and other modifications.
     
       
    Auditing and Reporting
    With the security audit trail reporting feature and support for event logging of key activities such as configuration changes, Multilin devices can help ensure device and protection system integrity, and perform forensic auditing of activities and changes for compliance.

    protection icon Protection
    New small signal oscillation detection protection element. With increasingly large interconnected power systems, one of the technical challenges is the inter-area low frequency oscillations. Inter-area oscillations not only limit the amount of power transfer, but also threaten system security and equilibrium, as they may lead to system instability and cascading outages. Therefore, it is essential to identify the characteristics of the inter-area oscillations, including oscillation frequency and damping ratio, so that proper actions can be taken based on the results. This is required to improve system damping and maintain stability in the power system. The C90Plus can detect these inter-area oscillations and provide an alarm or even trip signal to prevent a large-scale system disturbance.
