Phasor Measurement Units Sample Clauses

The Phasor Measurement Units clause defines the requirements and standards for the installation, operation, and maintenance of devices that measure electrical waves on an electricity grid. Typically, this clause specifies the technical specifications for the units, such as accuracy, data reporting intervals, and communication protocols, and may outline responsibilities for data sharing and system integration. Its core function is to ensure reliable, real-time monitoring of grid stability and performance, thereby supporting grid management and enhancing the detection and response to disturbances.
Phasor Measurement Units. A Developer shall install and maintain, at its expense, phasor measurement units (“PMUs”) if it meets the following criteria: (1) completed a Class Year after Class Year 2017; and (2) proposes a new Large Facility that either (a) has a maximum net output equal to or greater than 100 MW or (b) requires, as Attachment Facilities or System Upgrade Facilities, a new substation of 230kV or above. PMUs shall be installed on the Large Facility on the low side of the generator step-up transformer, unless it is a non-synchronous generation facility, in which case the PMUs shall be installed on the Developer side of the Point of Interconnection. The PMUs must be capable of performing phasor measurements at a minimum of 60 samples per second which are synchronized via a high-accuracy satellite clock. To the extent Developer installs similar quality equipment, such as relays or digital fault recorders, that can collect data at least at the same rate as PMUs and which data is synchronized via a high-accuracy satellite clock, such equipment would satisfy this requirement. Developer shall be required to install and maintain, at its expense, PMU equipment which includes the communication circuit capable of carrying the PMU data to a local data concentrator, and then transporting the information continuously to the Connecting Transmission Owner and the NYISO; as well as store the PMU data locally for thirty days. Developer shall provide to Connecting Transmission Owner and the NYISO all necessary and requested information through the Connecting Transmission Owner’s and the NYISO’s synchrophasor system, including the following: (a) ▇▇▇▇▇ ▇▇ and MVAR measured at the Developer side of the generator step-up transformer (or, for a non-synchronous generation facility, to be measured at the Developer side of the Point of Interconnection); (b) generator terminal voltage and current magnitudes and angles; (c) generator terminal frequency and frequency rate of change; and

Phasor Measurement Units. An Interconnection Customer shall install and maintain, at its expense, phasor measurement units (“PMUs”) if it meets the following criteria: (1) completed a Class Year Study or Cluster Study after Class Year 2017; and (2) proposes a new Facility that either (a) has a maximum net output equal to or greater than 100 MW or (b) requires, as Attachment Facilities or System Upgrade Facilities, a new substation of 230kV or above. PMUs shall be installed on the Facility on the low side of the generator step-up transformer, unless it is a non-synchronous generation facility, in which case the PMUs shall be installed on the Interconnection Customer side of the Point of Interconnection. The PMUs must be capable of performing phasor measurements at a minimum of 60 samples per second which are synchronized via a high-accuracy satellite clock. To the extent Interconnection Customer installs similar quality equipment, such as relays or digital fault recorders, that can collect data at least at the same rate as PMUs and which data is synchronized via a high-accuracy satellite clock, such equipment would satisfy this requirement. Interconnection Customer shall be required to install and maintain, at its expense, PMU equipment which includes the communication circuit capable of carrying the PMU data to a local data concentrator, and then transporting the information continuously to the Connecting Transmission Owner and the NYISO; as well as store the PMU data locally for thirty (30) Calendar Days. Interconnection Customer shall provide to Connecting Transmission Owner and the NYISO all necessary and requested information through the Connecting Transmission Owner’s and the NYISO’s synchrophasor system, including the following: (a) ▇▇▇▇▇ ▇▇ and MVAR measured at the Interconnection Customer side of the generator step-up transformer (or, for a non-synchronous generation facility, to be measured at the Interconnection Customer side of the Point of Interconnection); (b) generator terminal voltage and current magnitudes and angles; (c) generator terminal frequency and frequency rate of change; and (d) generator field voltage and current, where available; and (e) breaker status, if available. The Connecting Transmission Owner will provide for the ongoing support and maintenance of the network communications linking the data concentrator to the Connecting Transmission Owner and the NYISO, consistent with ISO Procedures detailing the obligations related to SCADA data.

  • Units Interests in the Partnership shall be represented by Units. The Units initially are comprised of one Class: Class A Units. The General Partner may establish, from time to time in accordance with such procedures as the General Partner shall determine from time to time, other Classes, one or more series of any such Classes, or other Partnership securities with such designations, preferences, rights, powers and duties (which may be senior to existing Classes and series of Units or other Partnership securities), as shall be determined by the General Partner, including (i) the right to share in Profits and Losses or items thereof; (ii) the right to share in Partnership distributions; (iii) the rights upon dissolution and liquidation of the Partnership; (iv) whether, and the terms and conditions upon which, the Partnership may or shall be required to redeem the Units or other Partnership securities (including sinking fund provisions); (v) whether such Unit or other Partnership security is issued with the privilege of conversion or exchange and, if so, the terms and conditions of such conversion or exchange; (vi) the terms and conditions upon which each Unit or other Partnership security will be issued, evidenced by certificates and assigned or transferred; (vii) the method for determining the Total Percentage Interest as to such Units or other Partnership securities; and (viii) the right, if any, of the holder of each such Unit or other Partnership security to vote on Partnership matters, including matters relating to the relative designations, preferences, rights, powers and duties of such Units or other Partnership securities. Except as expressly provided in this Agreement to the contrary, any reference to “Units” shall include the Class A Units and any other Classes that may be established in accordance with this Agreement. All Units of a particular Class shall have identical rights in all respects as all other Units of such Class, except in each case as otherwise specified in this Agreement.
