GB/T 20319-2017 Wind turbine generator systems — Specification for acceptance
1 Scope
This standard specifies the general principles, contents and methods of pre-acceptance and final acceptance after installation, commissioning and grid-connected generation of wind turbine generator systems.
This standard is applicable to horizontal axis wind turbine generator systems (hereinafter referred to as "units") with a swept area of more than 200m2.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in GB/T 2900.53 and the following apply.
3.1
commissioning testing
an abbreviation for adjustment and test. After the unit is installed, it is a general term for adjustment, adjustment and a series of test work according to the unit design document and commissioning outline
3.2
test run
running test to check its running stability and power generation capacity, after power-on commissioning of the unit and before the formal full operation
3.3
pre-acceptance
acceptance carried out to check whether the unit can continue to run safely and stably after the commissioning testing is completed
3.4
warranty period
a certain period of time (usually in years) after the pre-acceptance of the equipment agreed in the equipment purchase contract, during which the equipment manufacturer (supplier) shall undertake the quality assurance obligations agreed in the contract
3.5
final inspection and acceptance
acceptance of the unit before the end of the warranty period to determine whether the unit meets the requirements of the contract
3.6
wind turbine failure
parking events in which the unit is unable to perform specified functions and cannot remotely reset and start operations, except in the case of preventive maintenance or other scheduled activities or lack of external resources. The failure is usually the state after the product itself has failed, but it can also exist before the failure. It can be measured by the failure frequency, mean time between failures (MTBF), and average troubleshooting time
3.7
leakage
material or fluid that shall not flow out or leak out of the unit, which flow out or leak out of the mechanical equipment, causing loss, is called leakage. According to the different degree of leakage, the oil can be divided into seepage oil, drip oil and flow oil
Note: Seepage oil - oil slowly through or ooze, do not form a continuous flow or droplets;
Dripping oil - leakage of oil in the form of droplets;
Flow oil - the rapid outflow of oil, forming a continuous flow or flow trace, causing a large number of leaks in a short time.
4 Acceptance conditions
4.1 Documents required before the pre-acceptance
The following documents shall be available before pre-acceptance:
a) The quality and explanatory documents of the unit and main components, including valid product certification certificate, product manual, installation, operation and maintenance manual, fault manual, product qualification certification documents and delivery inspection and test report provided by the manufacturer;
Note: The main components in this standard refer to the unit blades, generators, gear boxes, main shafts, main bearings, variable propeller systems, yawing systems, converters, and main control systems.
b) Installation work acceptance documents, including basic quality acceptance documents submitted by the unit's basic construction party and installation work quality acceptance documents submitted by the unit's installation and construction party;
c) Unit commissioning testing report (including safety and function test);
d) Grid-connected characteristics test report of supply models;
e) Power curve test report of supply models;
f) Equipment purchase contract;
g) Equipment supervision quality documents (if agreed).
4.2 Documents required before final inspection and acceptance
In addition to the documents listed in 4.1, the following documents shall be prepared before the start of final inspection and acceptance:
