Moderator: We are aware that the access thresholds for domestic wind power should be more stringent, such as the performance, quality, and grid-connected standards of power generation. What is your opinion on this?
Zhang Binquan: I believe this is a very positive development. The state’s increasing focus on wind power equipment has greatly supported this shift, moving from a quantitative growth model to one that emphasizes quality. In fact, United Power has actively participated in the formulation and revision of several national standards. Some of these were even developed by our own technical team.
We strongly believe that raising the technical threshold plays a crucial role in the healthy development of the wind power industry. It encourages all stakeholders to focus on the long-term value of their products—ensuring that each unit can operate safely and reliably for 20 years, delivering consistent returns to the owner. United Power has a research and development team of nearly 200 people, and we have also imported advanced engineering software from both domestic and international sources. Our technical system now covers everything from wind resource analysis, new model development and simulation, testing, production, commissioning, to after-sales service. Additionally, we have nearly 1,000 maintenance and repair teams across the country.
On the design side, we have developed large-scale, low-speed wind turbines, while also taking into account local conditions. For example, we consider different terrain features, transportation challenges, and marine environments when selecting materials. We have our own customized solutions to address these issues.
Wind turbines often operate in remote and decentralized locations. The challenge lies not only in installation but also in ensuring smooth operation over time. In line with China’s “Strengthening the Information Industry†strategy, United Power has independently developed a data operation platform. This platform connects the operational data of over 5,000 wind turbines to a central data center. Each turbine has its own unique file, and its status is monitored in real-time every minute. If an issue arises, our backend experts can guide the nearest field engineer to the site to resolve it quickly.
For us, wind power development isn’t just about designing and manufacturing—it also includes operating and maintaining the units. In addition, there have been enhanced requirements related to grid adaptability. I think this is another positive step. Currently, we are working closely with the grid to forecast wind power output, helping the grid better understand the patterns of wind generation and adjust accordingly. In the future, we plan to introduce technologies such as low-voltage ride-through, high-voltage ride-through, and active/reactive power compensation to further improve grid compatibility.
This mutual support between the grid and wind power helps address the inherent electrical characteristics of wind energy and supports the growth of the wind power market. By aligning with grid needs, we can ensure more stable and efficient integration of renewable energy into the national power system.
Screws are threaded fasteners that create permanent or temporary assemblies. They are inserted and removed by turning in one direction or another. Wood screws, floor screws, and sheet metal screws have flat heads that sit flush when holding material together. Machine screws fasten metal to metal and are inserted into a prethreaded hole or mated with a nut. Thread-cutting screws are self-tapping screws that cut away and remove the surrounding material to create a tapped hole. Deck screws resist rust and corrosion to hold outdoor decking materials together. Drywall screws have fine tips, coarse threads, and tapered bugle heads to penetrate drywall and grip wood without damaging material. Hex-head bolts, cap screws, and lag screws are driven with wrenches rather than screwdrivers or drill bits. Captive panel screws and thumb screws can be tightened and loosened without tools on parts that are frequently removed such as access panels. Screw caps can help to cover screw heads for both safety and aesthetic purp
