Fast Load Shed Benefits

• Fast optimal load shedding executed within 20ms
• Intelligently sheds loads to maintain system/process integrity
• Highly customizable and scalable, integrating easily into most industrial plants with new or existing EMS/SCADA
• Optional stand-alone system with local HMI for viewing dedicated system status and reports
• Suitable for small or large industrial systems without re-design

• Easy to use system where settings and priorities can be configured within seconds

   

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.

Recording capability

There are three recorders available within the C90^Plus 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 C90^Plus 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

Key Features

• HMI can show fault reports to local operators, enabling quick access to time sensitive information
• Customizable annunciator panel, capable of handling up to 288 alarms using a pallet of 16 colors
• Front panel display of results from the self-tests performed, allowing easy maintenance and viewing of critical indications
• Access product information, such as IP addresses and serial numbers, without the need to connect to the unit
• Increase network availability by reducing failover time to zero through IEC62439-3 “PRP” support
• IP addresses and serial numbers of each module are also accessible without the need to connect to the unit
• Full color customizable local HMI allowing easy and secure control
• HMI-equipped with pre-built screens or configurable to display any single diagram
• Reliable communication card with automatic failover and extremely fast redundant schemes
• Inter-relay communication card enables implementation of pilot schemes based on standard communication protocols
• Both “Direct” and “Teleprotection” I/O elements

Advanced communications

The C90^Plus provides for secure remote data and engineering access, making it easy and flexible to use and integrate into new and existing infrastructures. Fiber optic Ethernet provides high-bandwidth communications allowing for low-latency controls and high-speed file transfers of relay fault and event record information. The availability of three independently configurable Ethernet options provide the means to create fault tolerant communication architectures in an easy, cost-effective manner. The C90^Plus supports the most popular industry standard protocols enabling easy, direct integration into SCADA systems.

• IEC 61850
• DNP 3.0
• Ethernet Global Data (EGD)
• IEC 60870-5-104
• Modbus RTU, Modbus TCP/IP
• PRP as per IEC 62439-3

Enervista software

The EnerVista™ suite is an industry-leading set of software programs that simplifies every aspect of using the C90^Plus relay. The EnerVista™suite provides all the tools to monitor the status of the protected asset, maintain the relay, and integrate information measured by the C90^Plus into DCS or SCADA monitoring systems. Convenient COMTRADE and Sequence of Events viewers are an integral part of the UR setup software included with every UR relay, to carry out postmortem event analysis and ensure proper protection system operation.

Security - enabling NERC CIP compliance

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 UR^Plus 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.
