New action on wind power standards! Jinan Hengsi Shanda took the lead in four new regulations, and equipment testing has rules to follow

Recently, the wind power industry has received heavy news. Jinan Hengsi Shanda, as the leading unit, jointly released four new standards for wind power equipment testing with multiple institutions, providing an important basis for the standardized development of the industry. This move not only fills the gap in the field of domestic wind power equipment testing, but also marks my country's wind power industry moving towards a higher level of standardization and specialization.

1. Core contents of the four new regulations

New action on wind power standards! Jinan Hengsi Shanda took the lead in four new regulations, and equipment testing has rules to follow

Standard nameMain contentScope of application
"Wind Turbine Blade Fatigue Test Specifications"The loading method, test cycle and evaluation index of blade fatigue test are clarifiedSuitable for onshore wind turbine blades above 1.5MW
"Wind Power Gearbox Vibration Test Method"Standardizes the measurement point layout, test conditions and data processing for gearbox vibration testingSuitable for wind power gearboxes above 3MW
"Testing Procedures for Tightening Force of Wind Turbine Tower Bolts"Developed technical requirements and acceptance standards for bolt tightening force testingSuitable for all onshore wind power towers
"Reliability Test Specifications for Wind Turbine Pitch System"Established an evaluation system and testing process for pitch system reliability testingSuitable for wind turbines above 2MW

2. Background of the introduction of new regulations

As my country's wind power installed capacity exceeds 400 million kilowatts, wind power equipment quality problems have become increasingly prominent. According to statistics, unplanned downtime of wind farms due to equipment quality problems will increase by 15% in 2023 compared with 2022.

yearsUnplanned downtime (hours/year)Main fault types
202186Electrical system failure
2022102Mechanical component failure
2023117Mechanical component failure

3. Significance of the implementation of new regulations

The four standards released this time have three important significances:

1.Improve equipment reliability: Through standardized testing methods, potential defects in equipment can be discovered in advance, which is expected to reduce the early failure rate by 15%-20%.

2.Unified industry testing standards: It solves the problem of inconsistent testing standards among manufacturers in the past and provides an objective basis for equipment quality evaluation.

3.Promote technological innovation: Provides standardized testing and verification methods for the application of new technologies and new materials, and promotes technological progress in the industry.

4. Opinions of Industry Experts

Director of the Wind Energy Professional Committee of the China Renewable Energy Society said: "The release of these four standards has filled many gaps in the field of wind power equipment testing in my country and is of great significance to improving the quality of wind power equipment and ensuring the safe operation of wind farms."

Technical Director of Jinan Hengsi Shanda pointed out: "It took us three years to complete the formulation of these four standards. During this period, we organized 28 expert demonstration meetings and collected data support from 42 wind farms across the country."

5. Future Outlook

It is reported that these four standards will be officially implemented from January 1, 2024. In the next step, the working group will continue to promote the formulation of five standards including the "Offshore Wind Power Equipment Testing Specifications" to further improve my country's wind power standard system.

Industry insiders predict that with the implementation of the new standards, the quality of my country's wind power equipment will be significantly improved, providing strong support for achieving the wind power installed capacity target during the "14th Five-Year Plan" period. At the same time, the improvement of standardization will also enhance the international competitiveness of my country's wind power equipment and support China's wind power "going global" strategy.
