DCRP/18/08/PC

DC0079 - Frequency Changes during Large Disturbances and their Impact on the Total System. July 2018
Target Audience

Industry stakeholders in particular from all current developers, owners and operators of embedded generation with plant rated >16A per phase commissioned before 1 February 2018

Summary

This Distribution Code public consultation is seeking the views from industry stakeholders in particular from all current developers, owners and operators of embedded generation with plant rated >16A per phase commissioned before 1 February 2018. The DC0079 workgroup is recommending that the Distribution Planning Code and EREC G59 should be changed to ensure that all existing embedded generators commissioned before 1 February 2018 make the necessary changes to comply with the following:

  • That where rate of change of frequency (RoCoF) protection relays are used, as part of Loss of Mains protection, the applied setting should be 1Hzs-1 with a definite time delay of 500ms.
  • That vector shift protection technique should be removed where it is in use as Loss of Mains protection.
  • That existing Loss of Mains protection settings for type-tested generators need not be changed.
  • Any existing over-frequency setting relays still set at 50.5Hz should if possible be reset to 52.0Hz.

This is the third phase of change with the two earlier phases having been approved by the Authority and subsequently implemented. They were:

  • implementing the banning of vector shift protection and the change in RoCoF relay settings from 0.125Hzs-1 to 1Hzs-1 with a definite time delay of 500ms for all new non type tested embedded generators commissioned on or after 1 February 2018 .
  • implementing the recommendations that all new type-tested plant connecting to the distribution network on or after 1 July 2018, will be expected to remain connected for a RoCoF of up to 1Hzs-1 with a 500ms time delay or a vector shift of ± 50 º.

The workgroup, through this latest DCRP/18/08/PC consultation, is recommending that the same requirements be applied retrospectively to existing non-type-tested plant within the scope of EREC G59 commissioned before 1 February 2018.

Given the retrospective nature of the proposed change, the DC0079 workgroup recommends the creation of an implementation team, with the governance, resourcing and stakeholder representation necessary to assure efficient and effective implementation of the proposed changes.
