Generation solutions from SEL help increase power system resiliency.
Generation is the beginning of everything in the electrical world. It is where mechanical energy gets converted to electrical energy through a complex system of prime movers, generators, transformers, inverters, sensors, and more. Without generation there is no transmission, distribution, or industrials.
Fundamentally, we need to generate electric power to meet the demand the moment it’s needed. That energy conversion starts at the generation source. The addition of renewables, retirement of traditional generation sources, and the sheer expanse of increasing power demands create a need for more reliable, efficient, and simple generation solutions.
Our generator protection solutions provide complete primary and backup protection from all types of faults.
SEL automation solutions integrate with relays, SCADA, and plant controls.
We provide turnkey solutions and services that help our customers protect and control generation systems across the globe.
SEL continues to innovate in the space of generation. We were the first to reimplement analog protection functions into digital relays, and then added in new features—like auto synchronization—to reduce cost and complexity of installation. We also added a loss-of-field element based on the generator capability curve in our generator protection relays, allowing the user to set multiple zones to prevent generator damage. We have designed new protection approaches that allow for redundant stator protection.
Our solutions are designed to protect the pieces you already have in place and add in more elements as your needs grow.
Protect and synchronize generators and their connection to the transmission grid. Steam/thermal plants have some of the largest generators in the power system and require comprehensive protection.
Reliable solutions to protect and control gas turbines and power plant systems. These units often operate during peak periods, requiring frequent starts and stops that may have unique protection requirements during starting.
Upgrade your protection system and implement automation and control schemes to improve efficiency, reliability, and safety. Hydro generators can vary greatly in size. Small hydro units may share a common bus which complicates the application of ground fault protection.
Monitor and coordinate wind turbine networks, maximize efficiency of output, and integrate generation with the utility grid.
Track and control solar installations and safely interconnect them with the utility grid.
Protect your generation assets and increase the reliability, safety, and efficiency of your plant’s power system with an SEL solution.
Optimize the resiliency and cost of any generation source or energy storage solution. Our microgrid control systems are designed to reduce capital expenditure, simplify integration and commissioning, and improve overall system resilience.
SEL is your partner in implementing generation solutions and tailoring them to your system priorities and requirements. We support new and existing plants as well as the integration of renewables and microgrids.
Industry-leading expertise on electric power system dynamics, protection, automation, and control.
Capabilities range from design-stage consulting and hardware-in-the-loop (HIL) testing to delivering turnkey power management systems. SEL employs hundreds of power system engineers around the globe who have designed complex power systems in industries such as mining, data centers, and oil and gas.
All forms of electric power system modeling and studies.
These services include load-flow, short-circuit, and stability studies for equipment sizing, scheme design, protection coordination, and arc-flash protection. Our teams also provide HIL testing for both protection and control systems.
Both custom and pre-engineered synchronization systems.
These systems automatically reduce voltage differences, phase angles, and slip before automatically closing a circuit breaker. The systems send control set points to any number of generators or inverters, and an SEL relay at each point of coupling automatically closes the circuit breaker once acceptable voltage differences, phase angles, and slip are detected.
Automation and SCADA Systems
We design, develop, test, and deploy complete SCADA systems to monitor and control.
Our engineers can work with legacy equipment, provide new SEL equipment, or integrate both to create an economical, high-quality system.
Select from multiple designs for asset optimization, load shedding, load restoration, outage management, predictive maintenance, access control, cybersecurity, and more.
SEL modeling experts perform complete fault studies to determine incident energy levels and design solutions.
We offer compliance assessments and can recommend and help implement the exact changes needed to bring your system into NERC compliance.
SEL SDN delivers high performance and reliability, simplifies network management, and enhances cybersecurity.
We believe you should never have to worry about whether your generation system will be working when you need it most. That’s why every device we manufacture comes with a ten-year warranty and free technical support.
It’s been this way at SEL since the company was founded nearly 40 years ago—a major reason why we’re North America’s most trusted provider of protective relays and ranked #1 by international utilities in price, service, and support.
