Before synchronization of the generating module, the producer must send to Elering for endorsement the design documentation on the electrical part of the generating module, which must receive endorsement from Elering seven days before the synchronization of the generating module. The electrical design documentation shall include:
- single-line diagram up to the TSO’s connection point (also includes data on the producer’s cable and transformer);
- technical parameter data sheets issued by the manufacturer for each different type of generating unit in the generating module;
- PQ diagram for the generating module’s active and reactive power calculated at the connection point;
- the basic data on the generating module pursuant to clause 18.104.22.168 of Annex 1 of the connection conditions;
- design project for the communication solution prepared in accordance with the guidelines “Kliendi elektripaigaldisega seotud andmevahetuse nõuded“ (Requirements for exchange of data related to customer’s electrical installation), accompanied by a list of the measurement and remote control signals to be transmitted.
- plan for testing of conformity of the generating module to the Grid Code, in accordance with the guidelines “Kliendi tootmismooduli katsetamise ja katsekava koostamise nõuded“;
- PSS/E and PSCAD models in accordance with the guidelines “Kliendi elektriosa projekti koostamise ja modelleerimise nõuded” (Requirements for preparation and modelling of the customer’s electrical design project); accompanied by co-operation simulation report.
The measurement and remote control signals to be sent out to the TSO in real time must function and be tested from the energy system control centre before synchronization of the generating module, and after synchronization along with the new generating module operating in parallel with the system within three months of synchronization.
After conformity testing, the producer must submit to the TSO for approval verified PSS/E and PSCAD models prepared in accordance with the guidelines “Kliendi elektriosa projekti koostamise ja modelleerimise nõuded” (Requirements for preparation and modelling of the customer’s electrical design project).
