Voltage Ride Through Sample Clauses
Voltage Ride Through. Whenever the utility Distribution System voltage at the Point of Interconnection varies from and remains outside the normal operating high and normal operating low region voltage for the predetermined parameters set forth in Table 1. The Facility’s protective functions shall cause the Facility’s Advanced Inverter(s) to Cease to Energize the utility Distribution System. Unless provided alternate settings by the Company, the Facility must comply with the voltage ride-through and trip settings specified in Table 1: The Facility shall stay connected to the utility Distribution System while the grid remains within the “Ride-Through Until” voltage-time range and must operate in accordance with the “Operating Mode” specified for each “Operating Region”. In the Continuous Operation region, the Facility’s Advanced Inverter shall reduce power output as a function of voltage, in accordance with section (iv) Volt-Watt of Rule 14H. Different settings than those specified in Table 1 may be specified by the Company Table 1: Voltage Ride-Through Table OV2 V > 120 Cease to Energize N/A 0.16 (1) OV1 120 ≥ V > 110 Mandatory Operation 0.92 1 CO 110 ≥ V > 100 Continuous Operation (Volt-Watt) N/A N/A CO 100 > V ≥ 88 Continuous Operation N/A N/A UV1 88 > V ≥ 70 Mandatory Operation 20 21 UV2 70 > V ≥ 50 Mandatory Operation ▇▇-▇▇ ▇▇-▇▇(2) UV3 50 > V Momentary Cessation N/A 2 (1)Must trip time under steady state condition. Inverters will also be required to meet the Company’s Transient Overvoltage criterion (TrOV-2). Ride-Through shall not inhibit TrOV-2 requirements.
Voltage Ride Through. The Resource shall remain on line for the voltage disturbance caused by any single or multi-phase fault on the LIPA transmission grid, having duration equal to the lesser of the normal fault clearing time, plus any subsequent post-fault voltage recovery to the final steady-state post-fault voltage. The initial conditions prior to such fault may include outage of any one LIPA transmission element, inclusive of both circuits of a double-circuit line sharing common transmission tower structures. The Resource shall remain online for any voltage disturbance caused by a single-phase fault on the transmission grid with delayed clearing, plus any subsequent post-fault voltage recovery to the final steady-state post-fault voltage. Clearing time shall be based on the maximum backup clearing time associated with a single point of failure (protection or breaker failure) for any single-phase fault location inclusive of single-phase faults occurring simultaneously on different phases of multi-circuit transmission lines. The initial conditions prior to such fault may include outage of any one LIPA transmission element, inclusive of both circuits of a double-circuit line sharing common transmission tower structures. The Resource shall recover to 90% of its pre-fault current output within 50 ms of the recovery of the point of interconnection positive sequence voltage to 0.85 per-unit of the nominal voltage. The Resource shall recover to the lesser of its pre-fault real power output or the available primary power, within 100 ms of the recovery of the point-of-interconnection positive sequence voltage to 0.95 per-unit of the nominal voltage, subject to the availability of the primary energy source. The Resource shall remain online and maintain stable operation in the post-fault state for the degraded short-circuit level conditions resulting from any fault condition described in (a) and (b), excluding fault conditions for which the clearing requires complete isolation of the Resource from the LIPA transmission system. The Resource shall not be required to remain online for system low-voltage disturbances creating a positive-sequence voltage component less than specified in Figure 3-1 for the cumulative durations shown, nor shall it be required to remain online for unbalanced system voltage disturbances creating a negative-sequence voltage greater than specified in Figure 3‑2 for the cumulative durations shown. The Resource shall remain on line for temporary overvoltages where...
Voltage Ride Through. The Facility shall have under-voltage and over-voltage ride through capability. The Facility shall behave as follows during under-voltage disturbances and over-voltage disturbances (“V” is the voltage of any of the three phases at the Point of Interconnection). For alarm conditions the Facility should not disconnect from the Company System unless the Facility’s equipment is at risk of damage. This is necessary in order to coordinate with the existing Company System:
(1) Undervoltage Ride-Through [TO BE DETERMINED BY COMPANY BASED ON RESULTS OF IRS]
(2) Overvoltage Ride-Through
1. 00 pu £ V < 1.10 pu The Facility remains connected to the Company’s System and in continuous operation.
Voltage Ride Through. The PCU shall remain connected to the grid during temporary dip or rise in grid voltage as per the LVRT and HVRT requirements of CEA Technical Standards for Connectivity to the Grid Regulations. The PCU shall also be able to inject reactive power during the period of voltage dip.
