SFS system stands for Safety Instrumented System, which is designed to prevent accidents by taking actions to maintain a safe state.

• SFS system is a critical part of process industries to ensure safety.

• It consists of sensors, logic solvers, and final control elements.

• The system continuously monitors the process and activates safety measures if necessary.

• Example: Emergency shutdown systems in oil refineries use SFS princ

The yaw system in wind turbines adjusts the angle of the rotor blades to optimize energy production by facing into the wind.

• Yaw system helps the wind turbine face into the wind for maximum energy production

• It consists of sensors to detect wind direction, a controller to adjust blade angle, and a yaw drive to rotate the nacelle

• The yaw system ensures the rotor blades are always perpendicular to the wind direction
