Introduction of GB/T 51311-2018

GB/T 51311-2018 Standard for debugging and acceptance of wind/PV/storage power plant 1General provisions 1.0.1 This standard is prepared with a view to ensure the construction quality of wind/PV/storagegenerating project and standardize the testing and acceptance of wind/PV/storage generating plants. 1.0.2 This standard is applicable to construction, renovation, and extension of onshore grid-connectedwind/PV/storage generating plants of 35kV and above. 1.0.3 In addition to the requirements stipulated of this standard, the testing and acceptance of wind/PV/storage generating plants shall also comply with requirements stipulated in the current relevantstandards of the nation. 2Terms 2.0.1 Wind power generating unit Generating unit consisting of a wind turbine generator system and a grid-connected boostertransformer,directly dispatched by SCADA. 2.0.2 Photovoltaic generating unitGenerating unit consisting of multiple PV module strings, combiner boxes, inverters, and anisolating booster transformer,capable of fulfilling grid frequency and voltage requirements. 2.0.3 Energy storage operation unit Energy storage unit consisting of energy storage components,energy storage converters ,and a grid-connected booster transformer, which can be dispatched directly by $CADA as an independent load orpower supply. 2.0.4 Wind power generating subsystem Generating subsystem consisting,of wind power generating units , collector system, switchgear, and a wind power SCADA. 2.0.5 Photovoltaic subsystem Generating subsystem consisting of photovoltaic generating units, collector system, switchgear, and a photovoltaic SCADA. 2.0.6 Energy storage subsystemSubsystem consisting of energy storage operation imnits, collector system, switchgears, and anenergy storageSCADA. 2.0.7 Wind/PV/storage generating plantHybrid generating plant consisting of wind power, PV, and electrochemical energy storage.operated joinily and controlled in coordination. 2.0.8 Coordination SCADA SCADA that is capable of coordinating the wind power, photovoltaic, energy storage subsystemsand substations in a wind/PV/storage generating plant. 3Basic requirements 3.0.1 The wind/PV/storage generating plant shall be subjected , in sequency.to equipment testing,subsystem testing and combined testing. The subsystem testing shall not procéed unless equipmenttesting is qualified , the combined testing shall not proceed unless subsystem testing is qualified. 3.0.2Before testing, unit works acceptance shall be completed and equipment shall be in satisfactorycondition for testing, and report shall be made to the superior dispatch organization. 3.0.3 Testing program shall be prepared before testing. Operational safety shall comply with currentnational standard GB 26860 Safety Code ofElectrie Powerindustry-Electric Part ofPower Plants andTransformer Substations. The testing report shall be provided onee testing is completed. 3.0.4 Testing engineers shall be familiar with eqgipment operation principles and have a knowledge ofthe basic structure , and the necessary mechanieal,eleefrical, testing and safety protection,and be able tocorrectly use the testing tools and safety equipment. 3.0.5 Testing instruments shall be inspeeted periodically for compliance with the testing requirements ,and shall be used within the term of waldityofverification and calibration by a metrological service. 3.0.6 The wind/PV/storage generating plant shall be subjected ,in sequence, to start-up acceptanceand commissioning,handover acceptance and completion acceplance before formal operation. 3.0.7 The Start-up Acceptance and Commissioning Commjtee is responsible for start-up acceptanceand commissioning ,the Handovef Acceptance Committee for handover acceptance,and the CompletionA cceptance Committee for completion acceptance, All aeceptance decisions at each stage shall subjectto the review and approval of the Acceptance Team(Committee). 3.0.8Aceeptance documentation shall be classified as documents for archival and documents for futurereferenice. The Related organizations shall bear responsibility for the authenticity , accuracy ,and integrityof the documentation and bear the corresponding liability. The content of acceptance documentationshall comply with the requirements of Appendix A and Appendix B of this standard.
