Harnessing the Wind with "Rules," Precision with Methods — MARINTECH Interprets GB/T 47560-2026 "Wind Energy Generation Systems — Technical Specification for Yaw Systems of Wind Turbines"

On August 1, 2026, a major national standard critical to the refined development of China's wind power industry officially came into effect — GB/T 47560-2026 "Wind Energy Generation Systems — Technical Specification for Yaw Systems of Wind Turbines."

Jointly issued by the State Administration for Market Regulation and the Standardization Administration of China as a nationally recommended standard, this document establishes new rules for the "wind-tracking" system of wind turbines. Today, MARINTECH takes you through an in-depth interpretation of this new national standard and explores how intelligent technologies can help the industry achieve efficient compliance.

01What is a yaw system?

01 The yaw system is one of the core components of a wind turbine, located between the tower and the main frame, and is often referred to as the turbine's "steering wheel." By sensing wind direction signals, it controls the rotation of the nacelle to ensure that the rotor always faces the wind, thereby maximizing wind energy capture.

An excellent yaw system directly determines the turbine's power generation efficiency and operational safety. The introduction of GB/T 47560-2026 fills a gap in the national standard for yaw systems, marking a new phase of greater standardization and refinement for China's wind power yaw systems.

02What does the new standard bring?

GB/T 47560-2026 applies to the yaw systems of horizontal-axis grid-connected wind turbines. It comprehensively covers the entire life cycle from design and manufacturing to operation and maintenance, specifying working conditions, technical requirements, inspection items and rules, delivery requirements, and assembly and maintenance for yaw systems, and describes the corresponding test methods.

The core orientation of the new national standard is: improving yaw accuracy, optimizing control strategies, and extending equipment service life.

03With the new standard in effect, how does MARINTECH help achieve efficient compliance?

The new national standard imposes higher technical requirements and presents new challenges for the refined operation of wind farms. MARINTECH has built a complete intelligent yaw solution from two levels: "sensing" and "decision-making."

Precise Sensing: Eliminating Wind Direction Data Bias

The accuracy of a yaw system first depends on precise data from wind direction sensors. If wind direction data is inaccurate, even the most powerful controller and drive unit cannot make correct judgments.

MARINTECH's independently developed XFC2-2 series heated wind speed and direction sensors are designed precisely to address this challenge. Featuring an internal heating design, these sensors ensure uninterrupted wind measurement data during freezing weather, greatly improving the availability of wind data in complex climates. At the same time, with large-tail vane physical filtering and vector measurement technologies, the XFC2-2 series can stably capture the prevailing wind direction even under turbulent conditions, providing the yaw system with authentic and reliable wind direction data, thereby enhancing yaw accuracy and wind-facing stability.

Smart Decision-Making: From "Passive Response" to "Active Prediction"

Accurate wind direction sensing is only the first step. Enabling turbines to execute yaw actions with optimal strategies under complex wind conditions is equally central to the new standard's concerns.

MARINTECH's independently developed DPM1-1 real-time dynamic yaw calibrator for wind turbines is a system-level response to this need. Built on high-precision wind measurement data and integrating LSTM neural network prediction with dynamic threshold adjustment technologies, this system delivers:

• Wind direction error calibration: With a built-in data calibration module, it performs real-time compensation and correction of static errors and measurement dead zones before wind direction signals enter the turbine's main controller, making every degree of wind direction data more authentic and reliable.

• Yaw strategy optimization: It analyzes historical wind direction data in real time and predicts trends, enabling refined yaw decision-making under turbulent and variable wind conditions, effectively reducing unnecessary yaw cycles.

• Reduced mechanical wear: By minimizing unnecessary yaw actions, it reduces wear on critical components such as the yaw bearing, gearbox, and brake, extending equipment service life.

04From "Meeting the Standard" to "Exceeding the Standard"

If the XFC2-2 series wind sensor is the "keen eye" of the yaw system, then the DPM1-1 real-time dynamic yaw calibrator is its "smart brain." The deep synergy between sensing and decision-making represents MARINTECH's comprehensive technological strategy for the new standard and the industry's future needs.

MARINTECH firmly believes that compliance is merely the starting point, while intelligentization is the direction. Whether through precise sensing or smart decision-making, MARINTECH continues to respond to industry standard upgrades with technological innovation, helping every wind turbine "track the wind with precision and generate power with efficiency."
