Phase Angle Shift Ride-Through Clause Samples
The Phase Angle Shift Ride-Through clause requires electrical equipment or systems to remain operational and stable during sudden changes in the phase angle of the power supply. In practice, this means that devices must be designed or configured to tolerate brief disturbances in the electrical grid, such as those caused by switching events or faults, without disconnecting or shutting down. This clause ensures the reliability and resilience of equipment, minimizing disruptions and maintaining continuous operation during grid disturbances.
Phase Angle Shift Ride-Through. The Facility equipment shall ride through phase angle shift of up to ([ ]) [Note – requirements will depend on Facility]. Inverter phase lock loop (PLL) loss of synchronism shall not cause the inverter to trip or enter momentary cessation within the voltage and frequency ride-through region. Inverters must be capable of riding through temporary loss of synchronism, and regain synchronism, without causing a trip or momentary cessation of the resource.
Phase Angle Shift Ride-Through. The Facility equipment shall ride through phase angle shift of up to 30 degrees. [Note – requirements will be confirmed upon completion of the IRS]
