Wintop Optical Yunnan photovoltaic power generation project was successfully connected to the grid to generate electricity

Photovoltaic energy generation, with its leading role in converting solar photons into electrical energy, has gradually become an important energy option as renewable energy demand increases and environmental issues arise. The school is becoming more and more prominent. With the continuous development of science and technology and the continuous innovation of technology, the efficiency of solar cells continues to improve and costs gradually decrease. The advancement of energy storage technology promotes the popularization of photovoltaic energy generation and lays a solid foundation for the future of photovoltaic energy generation. Globally, strong government support and active market promotion have pushed photovoltaic power generation to new heights. The installed capacity of photovoltaic power generation continues to increase, and it is expected that the position of photovoltaic power generation in the energy sector will be further strengthened in the future.

Donglao photovoltaic power generation project, located in Gengma district, Lincang city, Yunnan province, covers an area of ​​about 1.66 million square meters and has an operating period of 25 years. It achieved full grid-connected generation capacity in June this year. Since the project came into operation, the daily electricity output has reached a maximum of 576,200 kWh, which 4,000 households can use in a month. The annual electricity output can reach 160 million kilowatt hours, which can reduce carbon dioxide emissions by about 139,300 tons. After electricity is generated through the booster station, it is connected to the local grid through a 110 kilovolt line, effectively enhancing the power supply to the area and ensuring energy supply security. Reduce carbon emissions and further promote the construction of clean, low-carbon, safe and efficient energy systems. Introduce “green” energy into the economic and social development of Lincang City and contribute to the goal of “carbon neutrality and carbon peaking”.

The new photovoltaic plant construction project of Gengma Donglao District Photovoltaic Power Generation Project is equipped with a total of 31 inverter communication cabinets. The current collection lines are divided into 5 groups and connected by direct buried fiber optic cables. Communication method: According to the layout of the box type substation and the collection line conditions, the box type substation data is connected to the inverter communication cabinet. 31 inverter communication cabinets are divided into 5 fiber optic communication rings; Fiber optic communication cable uses GYFTA53-16B1 fiber optic cable. The inverter switch, video switch, and fiber optic junction box are located in a low-voltage cabinet on the low-voltage side of the box-type transformer. To ensure normal transmission of monitoring data, all on-site switches must have ring network function.

Photovoltaic plants are mainly built in complex terrain conditions such as mountains and hills. The surface of the building is undulating and has many different directions. Environmental extremes can include extreme climatic conditions, high or low temperatures, high humidity, sandstorms, strong winds, etc. Conditions are very difficult. Extreme testing is unprecedented, requiring high demands on the performance and tolerance of configured and installed equipment to ensure stability and reliability in system operation.

Project requirements

There are many types of monitoring equipment associated with photovoltaic plants and there is a need to understand power plant operations in real time. Therefore, establishing a complete monitoring system is an urgent need. The environment where photovoltaic stations are located is very harsh, and the performance requirements for the transmission equipment (industrial switches) of the photovoltaic station monitoring system are quite strict. Therefore, implementing remote and unattended management in power plants is of great significance. If a power plant is truly unattended, it must provide the necessary security guarantees for the power plant itself and monitor various objects such as environmental conditions, key equipment and locations. important location so that the power plant can be truly unattended.

There are 31 box transformers at the Donglao Photovoltaic Power Generation Facility in Gengma District, and each box transformer cabinet is equipped with an RS608-2F6T ring network switch. The site is divided into 6 ring networks and a CM6124-12GF12GT access switch is configured in the core area. The solar box transformer uses RS608-2F6T 100M optical port to form a ring network, which has the characteristics of high bandwidth, high stability and high real-time performance. The fiber optic ring network adopts a protection mechanism to effectively prevent network errors caused by fiber damage and achieve ring network self-healing time < ;20ms. In addition, because some equipment in photovoltaic power plants will generate strong electromagnetic fields, there are high requirements for electromagnetic compatibility of industrial switching equipment in communication networks. Wintop optical industrial switches have passed EMC industrial level 4 electromagnetic compatibility standard certification and are equipped with rich fiber optic ports. Because optical fibers are basically not disturbed by electromagnetic fields, they have long transmission distances and high bandwidth, which can effectively resist the strong electromagnetic interference of wind farms and ensure stable system operation. stable, reliable in harsh environments and has been widely used. used in the photovoltaic energy production industry.
