Power Generation
SEL’s power interconnection, protection, communications, control, and metering equipment is ideally suited for large and small electrical generation and distributed power sources of all types. SEL products and systems protect and control generators and plants that use hydroelectric, coal, gas, geothermal, wind, biofuel, solar, and other energy sources.
- Biomass
Converting waste into electricity through biomass power plants is economical and renewable, and reduces waste. Complete protection, including optional differential protection, makes our relays ideal for all generator sizes and configurations.
- Coal
New technologies continue to help coal plants produce electricity with fewer emissions. Operators need flexibility and fast response times to handle changing conditions and variable power demands. SEL relays will speed repair and troubleshooting to reduce costs and keep units online.
- Cogeneration/CHP
Coordination between steam demands and power generation requires fast and accurate control. SEL’s industry-leading quality, reliability, and service will help optimize plant generator capacity.
- Gas
Our wide range of equipment and extensive services protect, monitor, control, and communicate with electric power systems, generators, motors, transformers, and related devices. Keep the plant running while improving safety and reliability with SEL products and services.
- Geothermal
Our engineers take a comprehensive approach to power system design and construction. From engineering studies and design to installation and testing, SEL provides cost-effective engineering, procurement, and construction (EPC) services to customers around the world.
- Hydroelectric
Enhance protection and reduce maintenance at vital dam and hydroelectric power plants. Provide high-speed protection for all types of phase and ground faults, including current and voltage elements, loss of field, 100 percent stator ground fault protection, differential protection, field ground resistance, and RTD thermal protection.
- Nuclear
SEL has supplied relays to nuclear plants for many years for nonsafety critical applications. Stringent engineering design processes, manufacturing, and quality review substantiate our commitment to quality.
- Solar
SEL solutions monitor and manage large and small electrical generation systems. Protect your equipment with the most reliable products in the industry. Make secure connections to the grid with IEEE 1547-2003-compliant relays.
- Tidal
Both electric utilities and independent power producers need cost-effective and reliable solutions that allow distributed generation to operate on the electric utility grid. SEL distributed-energy solutions provide protection, metering, and control for distribution-interconnected generation. Make secure connections to the grid with IEEE 1547-2003-compliant relays.
- Waste-to-Energy
New capture, generation, monitoring, and control methods allow previously wasted gas to be converted into valuable energy. Our solutions are ideally suited for metering and protecting methane-powered generation. Make secure connections to the grid with IEEE 1547-2003-compliant relays.
- Wind
The smart grid easily accepts renewable and intermittent energy sources and transmits that energy without waste or loss of stability, saving money for energy customers. Precise and real-time measurements of power system properties are critical features of this grid. Use our time-synchronized phasors to obtain these measurements for more efficient, reliable, economical, and safe electrical energy transfer from generation to the customer. Make secure connections to the grid with IEEE 1547-2003-compliant relays.
