Xingyi Joins Hands with Central State-Owned Enterprises to Achieve "Three Breakthroughs" in Photovoltaic Projects

Recently, the rooftop distributed photovoltaic project at China Construction Technology Industrial Park, constructed by Xingyi Technology Group for the headquarters of China State Construction Third Bureau, was officially connected to the grid and began generating clean energy. As the first integrated industry-city demonstration park under the dual-brand initiative of "China Construction Star" and "China Construction Industrial Park" from China State Construction Third Bureau, the park has also been selected as one of the first demonstration parks in Wuhan’s Design Capital program. This project serves as a flagship initiative in Wuhan’s commitment to the "Dual Carbon" strategy, with the implementation of the PV project marking a crucial step toward advancing that ambitious goal. In this project, Xingyi achieved three major breakthroughs, fully highlighting the company’s robust capabilities in the renewable energy sector.

Technological breakthrough: Multiple technological innovations lead to the independent design of an intelligent photovoltaic power plant.

During the project construction, Xingyi New Energy's technical team actively tackled key technological challenges. Leveraging the specific conditions of the project site, they custom-designed and developed their own photovoltaic power station step-up transformers along with primary and secondary prefabricated cabins. To address the weight limitations posed by installing the photovoltaic step-up transformer at an altitude of 100 meters, the team meticulously optimized the design by incorporating high-strength, lightweight materials—achieving a significant reduction in equipment weight while maintaining stringent safety standards. Additionally, given the project’s remote location from the nearest substation, the team pioneered the use of a wireless access method for dispatch automation, capitalizing on the technology’s low deployment complexity and exceptional flexibility. This innovative approach not only streamlined construction processes and cut costs but also dramatically enhanced the efficiency of data transmission within the dispatch automation system, making operations and maintenance far more convenient.

The independently developed prefabricated cabin features primary equipment equipped with dual protection systems—both microcomputer-based five-protection mechanisms and mechanical interlocks—to ensure the safe operation of the photovoltaic power plant. Meanwhile, the secondary equipment integrates AI algorithms with wireless communication technology, enabling advanced development and optimized integration of functions such as solar power forecasting, AGC/AVC control, and backend monitoring. This results in real-time, precise management, millisecond-level fault response, and intelligent early warning systems, ultimately guaranteeing the smart and highly efficient operation of the photovoltaic power plant.

Breaking through in construction: Optimizing the construction plan to tackle challenges in high-altitude work and heavy equipment lifting.

In terms of construction innovation, Xingyi carefully organized and meticulously planned the project based on the actual site conditions. Specifically for lifting and installing a step-up transformer substation weighing over 10 tons and positioned at an installation height exceeding 100 meters, the project team implemented several key measures: using high-strength, lightweight materials, developing a specialized construction plan tailored for this "critical and complex project," and optimizing the lifting methodology. Ultimately, they relied on a powerful 400-ton crane to ensure the smooth execution of both the lifting operation and the overall construction process.

Given the limited space available for installing the prefabricated cabin, and taking into account the specific on-site conditions, the cabin was placed in the courtyard. This solution not only optimizes the distance between the step-up transformer housed in the prefabricated cabin and the distribution room but also seamlessly integrates the large-scale power equipment into the user’s overall layout—without disrupting the existing landscape.

Breaking through in project timelines: With tight deadlines and heavy workloads, the project set a new record by delivering in just 20 rapid days.

In project schedule management, Xingyi has achieved "accelerated progress." By establishing a "specialized task force" to implement meticulous, end-to-end management, the company has reduced the project timeline from the usual 35 days down to just 20 days. From design drawings to raw material procurement, from production and assembly to inspection and commissioning, all steps—from on-site installation—have been seamlessly coordinated and swiftly executed, enabling the project to be delivered in an impressive 20-day turnaround.

Faced with the shortage of photovoltaic modules, the company swiftly mobilized by assigning dedicated personnel to stay on-site, closely monitoring production and coordinating batch shipments to ensure that construction progress at the site remained on track. Given the unique challenges of the office building construction project—specifically, certain phases required halting work during daylight hours while working overtime at night—Xingyi employees rose to the occasion, meticulously planning and executing the schedule to simultaneously uphold both construction timelines and quality standards.

This time, through our collaboration with China Construction Third Bureau on the photovoltaic project, Xingyi is leveraging its comprehensive strength and expert expertise in the new energy sector to empower the development of a zero-carbon park. Moving forward, Xingyi will continue to deepen its focus on the new energy industry, contributing to the achievement of the "Dual Carbon" goals and driving the advancement of green energy initiatives.
