Voltage/Reactive Power Requirements Sample Clauses

Voltage/Reactive Power Requirements. Electricity generated by the Seller shall be delivered to the Company at the Point of Interconnection in the form of 3-phase, 60 hertz (nominal) alternating current at the normal operating voltage of 69 kV. The actual operating voltage will be determined by the Company.

Voltage/Reactive Power Requirements. Electricity generated by the Seller shall be delivered to the Company at the Point of Interconnection in the form of 3-phase, 60 Hertz alternating current at a nominal operating voltage of 69 kV. The actual operating voltage will be determined by the Company. Reactive kVAr requirements will be from 0.90 leading to 0.85 lagging power factor delivered by the Seller to the Company. The Facility generators must be capable of automatically adjusting reactive control to maintain the bus voltage to meet the target specified by the System Operator. The target will be specified remotely by the System Operator through the EMS. The generators should not normally operate on a fixed var or fixed power factor setting except during startup or shutdown or if agreed by the Company. 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):

Voltage/Reactive Power Requirements. (a) Electricity generated by Seller shall be delivered to the Company at the Point of Interconnection in the form of 3-phase, 60 hertz (nominal) alternating current at the normal operating voltage of 69 kV. The actual operating voltage will be determined by Company. (b) The Facility must deliver power up to the Firm Capacity at a power factor between 0.90 lagging and 0.95 leading to the Company System. The Facility generator must be capable of automatically adjusting reactive control to maintain the bus voltage at the Point of Interconnection to meet the scheduled voltage set point target specified by the Company System Operator. The voltage target will be specified remotely by the Company System Operator through the SCADA/EMS. The Facility’s voltage set point target must reflect the Company voltage set point target issued from the SCADA/EMS, without delay. The generator should not normally operate on a fixed var or fixed power factor setting except during startup or shutdown or if agreed by Company. The voltage setpoint target, and present Facility minimum and maximum reactive power limits based on the Facility real power export and the unit capability curve shall be provided to the Company EMS through the RTU telemetry interface. (c) 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 Seller reasonably determines based upon Good Engineering and Operating Practices that the Facility’s equipment is at risk of damage. This is necessary in order to coordinate with the existing Company System: V ≥ 0.80 pu The Facility remains connected to the Company System in continuous operation. 0.00 pu ≤ V < 0.80 pu The Facility remains connected to the Company System and in continuous operation for a minimum of 600 milliseconds (while “V” remains in this range). The Facility may initiate an alarm if “V” remains in this range for more than 600 milliseconds; the duration of the event is measured from the point at which the voltage drops below 0.75 pu. and ends when the voltage is at or above .75 pu. The 600 milliseconds represents a delayed clearing time of 30 cycles plus breaker opening time. 1. 00 pu ≤ V < 1.10 pu The Facility remains connected to the Company System and in contin...

  • Power Factor Design Criteria (Reactive Power A wind generating plant shall maintain a power factor within the range of 0.95 leading to 0.95 lagging, measured at the Point of Interconnection as defined in this LGIA, if the ISO’s System Reliability Impact Study shows that such a requirement is necessary to ensure safety or reliability. The power factor range standards can be met using, for example without limitation, power electronics designed to supply this level of reactive capability (taking into account any limitations due to voltage level, real power output, etc.) or fixed and switched capacitors if agreed to by the Connecting Transmission Owner for the Transmission District to which the wind generating plant will be interconnected, or a combination of the two. The Developer shall not disable power factor equipment while the wind plant is in operation. Wind plants shall also be able to provide sufficient dynamic voltage support in lieu of the power system stabilizer and automatic voltage regulation at the generator excitation system if the System Reliability Impact Study shows this to be required for system safety or reliability.
