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.

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.
