Grid code compliance
|Publication Date:||1 March 2016|
Scope and application
This standard is applicable to all types of units as well as for plants (plants are usually several electrically connected units, Figure 1-3), modules and facilities (several interconnected plants, Figure 1-1). Furthermore it is applicable to all parts, sub-components or part functionalities and any other electrical equipment related to it. The scope of individual assessment for verification or certification is described in [3.1.3] of DNV-SE-0124 /32/, and shall be defined for each individual case of assessment or verification.
See also the following two Guidance Notes for scope of assessment and structural integrity risk.
Guidance note 1:
The principle of assessment scope for certification according to /32/ is to limit the scope of this standard by the scope of the grid codes applied, depending on the GCC class chosen. The applicable scope of assessment for each certification is defined within the definition phase according to DNV-SE-0124 /32/. More details upon assessment scope can be seen in [2.1] of this standard.
Guidance note 2:
The structural integrity assessment for units and plants is outside of the scope of this standard. Nevertheless it is very important to evaluate the safe operation of the unit or plant especially during grid failure. This includes the evaluation of the relevant ranges of the safety system, protection and monitoring devices as well as the relevant ranges of the load assumptions.
This should be evaluated within the scope of a corresponding structural integrity assessment. This applies e.g. if rotating parts are involved in the unit and issues like over speed impose a risk to the unit's structural integrity, e.g. in the case of wind turbines. The evaluation is part of the design evaluation according to the respective standards and guidelines (e.g. GL IV-1 /15/, GL IV-2 /17/, IEC 61400-22 /14/ or DNV-SE-0074 /27/).
