Shanghai Zikai Electric empowers "fishery and photovoltaic integration", writing a new green chapter in rural revitalization
The 5-megawatt fishery-photovoltaic complementary project in Yuanbaizhuang, Shandong Province, is located in Yanggu County, Liaocheng City, Shandong Province. It is a key "agriculture-photovoltaic complementary" demonstration project being promoted in the western part of Shandong Province. The project has achieved a three-dimensional development model of "generating electricity on water and raising fish underwater" by installing photovoltaic panels above the fish ponds. This not only enhances the comprehensive utilization rate of the land but also injects green energy into rural revitalization.
Shanghai Zikai Electric Co., LTD., as the core power distribution equipment supplier of the project, provided a complete set of intelligent power distribution solutions for the fishery and photovoltaic complementary system, helping it achieve safe grid connection and efficient operation, and setting a benchmark for the local energy structure transformation and the coordinated development of ecological economy.
Customized fishery and photovoltaic complementary power distribution system
In response to the humid and highly corrosive nature of the fishpond environment, Zikai Electric has designed a waterproof and rust-proof power distribution structure, which includes core equipment such as gas-insulated switchgear, ring main units, box-type substations, and primary and secondary integrated pole-mounted circuit breakers. The protection level reaches IP66, ensuring long-term stable operation.
It adopts dual-circuit power supply and intelligent grid connection control to adjust the interaction between photovoltaic power and the power grid in real time, ensuring the priority of power supply for fish pond breeding while maximizing the consumption of clean energy.
Intelligent operation and maintenance and energy efficiency improvement
Integrate an Internet of Things (iot) monitoring platform to monitor in real time the power generation efficiency of photovoltaic arrays, the status of inverters, and water quality parameters of fish ponds (such as dissolved oxygen and pH value), achieving collaborative management of "photovoltaic - fishery".
Through the intelligent reactive power compensation device (SVG), the power factor of the power grid is dynamically adjusted to improve power quality and reduce the line loss rate to below 3% (data example).
Dual benefits of ecology and economy
The average annual power generation of the project is approximately 6 million kilowatt-hours, equivalent to reducing carbon emissions by 4,500 tons and saving 1,800 tons of standard coal (data example).
The area of fish ponds has not decreased. Instead, the shading effect of photovoltaic panels has improved the growth environment of fish, and the comprehensive income has increased by more than 20%.
The project leader of Shandong Yuanbaizhuang said, "The fishery-solar complementary system of Zikai Electric not only solves the power distribution problem in the complex environment of fish ponds, but also its intelligent management function enables us to achieve 'fish farming and power generation at the same time'." This innovative model provides a replicable sample for rural revitalization in the surrounding towns and townships!
The successful implementation of this project marks the mature application of the "fishery and photovoltaic integration" model in the Huang-Huai-Hai Plain, providing a new paradigm for exploring the path of coordinated development of ecological economy in the vast rural areas of our country.
The successful delivery of this project once again confirms Shanghai Zikai Electric's technical strength and innovative vitality in the field of new energy distribution. In the future, the company will continue to take "safer electricity and more efficient usage" as its mission, and join hands with partners to inject vigorous green energy into the realization of the "dual carbon" goals!
