Examples of NI System in a sentence
Cancelled Start A response by a Generator to an instruction from the TSO cancelling a previous instruction to Synchronise to the NI System.
The TSO will also indicate where a need exists to use Intertripping, emergency switching, emergency load management or other measures including restrictions on the Dispatch of CDGUs and/or Dispatchable WFPS and/or Controllable WFPSs to allow the security of the NI System to be maintained within the Licence Standards.
Whilst responding to Frequency deviations on the NI System the PPM shall ramp at the Frequency Response Ramp Rate, this ramp rate shall be the maximum ramp of the Generating Units and as a minimum shall be: Primary Response capability of the Power Park Module (Available by 5s and sustained to 15s): 60% of expected MW Output change value based on droop characteristic.
It should be noted by the Generator that if SONI/NIE Networks deem the Power Park Module to be of a Registered Capacity which may have an impact on NI System during Compliance testing, SONI/NIE Networks has the right to insist theGenerator follow the procedures laid out in Grid Code OC10 System Tests in addition to what is laid out in this PPM Setting Schedule.
CC.S1.5 Generating Unit Control Arrangements CC.S1.5.1 Each Generating Unit must be capable, in accordance with CC.S1.5.2 and CC.S1.5.3, of contributing appropriately, as reasonably specified by the TSO, to Frequency and voltage control by continuous modulation of Active Power and Reactive Power supplied to the NI System.
Failure to complete Compliance testing in the stipulated timelines while conditions were suitable for testing will result in the Interim Operational Notification for the Power Park Module being revoked and the PPM will be disconnected from the NI System until the Generator is in a position to resume Compliance testing.
Where a Generating Unit or Power Station becomes isolated from the rest of the NI System but is still supplying Customers, the speed governor must also be able to contribute to controlling NI System Frequency to below 52 Hz. As stated in CC5.3.2, the NI System Frequency could rise to 52 Hz or fall to 47 Hz. For steam turbine Generating Units the governor must be designed and operated to the relevant requirements of BS132.
The objective of OC3 is to detail the provisions to be undertaken by the DNO required to achieve a reduction in Demand to avoid or relieve operating problems on all or any part of the NI System and, subject to the circumstances set out in paragraph 1.
The target clearance times are measured from fault current inception to arc extinction and will be specified by the TSO to meet the requirements of the relevant part of the NI System.
The TSO will indicate to a Generator where a need may exist to use Intertripping or other measures including restrictions on the Dispatch of CDGUs and/or Dispatchable WFPS and/or Controllable WFPSs to allow the security of the NI System to be maintained within the Licence Standards.
