P 8.3 Power Generating Modules with a Connection Point at LV Type B C D Power Generating Modules. N/A 8.3.1 LV Distribution Networks are always solidly earthed, and the majority are multiple earthed. Design practice for protective multiple earthing is detailed in the Energy Networks Association publications including Engineering Recommendation G12, and in the references contained in those publications.
N/A 8.3.2 The winding configuration and method of earthing connection shall be agreed with the DNO. Info. 8.3.3 In addition, where the Power Generation Facility’s Connection Point is at Low Voltage the following shall apply: Where an earthing terminal is provided by the DNO it may be used by a Power Generation Facility for earthing the Power Generating Module, provided the DNO earth connection is of adequate capacity. N/A 9 Network Connection Design and Operation P 9.1 General Criteria P 9.1.1 As outlined in Section 5, DNOs have to meet certain statutory and Distribution Licence obligations when designing and operating their Distribution Networks.
These obligations will influence the options for connecting Power Generating Modules. P 9.1.2 The technical and design criteria to be applied in the design of the Distribution Network and Power Generating Module connection are detailed in this document and DPC 4 of the Distribution Code. The criteria are based upon the performance requirements of the Distribution Network necessary to meet the above obligations. P 9.1.3 The Distribution Network, and any Power Generating Module connection to that network, shall be designed:
P (a) to comply with the obligations (to include security, frequency and voltage; voltage disturbances and harmonic distortion; auto reclosing and single phase protection operation). P (b) according to design principles in relation to Distribution Network’s plant and equipment, earthing, voltage regulation and control, and protection as outlined in DPC4, subject to any Modification to which the DNO may reasonably consent.
