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

 Photovoltaic power generation, as the leader in converting solar photons into electrical energy, has gradually become an important energy choice as the demand for renewable energy increases and environmental issues become increasingly prominent. With the continuous development of science and technology and the continuous innovation of technology, the efficiency of solar cells continues to improve and the cost gradually decreases. The advancement of energy storage technology promotes the popularization of photovoltaic power generation and lays a solid foundation for the future of photovoltaic power generation. Globally, strong government support and active market promotion have pushed photovoltaic power generation to a new level. The installed capacity of photovoltaic power generation continues to increase, and it is expected that the position of photovoltaic power generation in the energy field will be further consolidated in the future.

  Project Introduction

The Donglao Photovoltaic Power Generation Project, located in Gengma County, Lincang City, Yunnan Province, covers an area of approximately 1.66 million square meters and has an operation period of 25 years. It achieved full capacity grid-connected power generation in June this year. Since the project was put into operation, the daily power generation has reached a maximum of 576,200 kilowatt hours, which can be used by 4,000 households for one month. The annual power generation can reach 160 million kilowatt-hours, which can reduce carbon dioxide emissions by about 139,300 tons. After the generated electricity is sent out through the booster station, it is connected to the local power grid through a 110-kilovolt line, effectively enhancing regional power supply and ensuring energy supply security. Reduce carbon emissions and further promote the construction of a clean, low-carbon, safe and efficient energy system. Inject "green" energy into Lincang City's economic and social development and contribute to the goal of "carbon neutrality and carbon peaking".

The new photovoltaic power station construction project of Gengma County Donglao 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 using direct buried optical 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. The 31 inverter communication cabinets are divided into 5 optical fiber communication rings; the communication optical cable adopts GYFTA53-16B1 optical cable. The inverter switch, video switch and optical fiber splicing box are arranged in the low-voltage cabinet on the low-voltage side of the box-type transformer. In order to ensure the normal transmission of monitoring data, all switch equipment on site must have ring network functions.

?Project Challenges

Photovoltaic power stations are mainly constructed in complex terrain conditions such as mountains and hills. The construction surface is undulating and has different orientations. The harshness of the environment may involve extreme climatic conditions, high or low temperatures, high humidity, sandstorms, strong winds, etc. The conditions are difficult. The severe test is unprecedented, so it requires high requirements on the performance and tolerance of the configured and installed equipment to ensure the stability and reliability of system operation.

Project requirements

There are many types of monitoring equipment involved in photovoltaic power stations, and it is necessary to understand the operation of the power station in real time. Therefore, it is an urgent need to establish a complete monitoring system. The environment in which photovoltaic power stations are located is very harsh, and the performance requirements for the transmission equipment (industrial switches) of the photovoltaic power station monitoring system are quite stringent. Therefore, it is of great significance to realize unattended and remote management in power stations. If a power station is to be truly unattended, it must provide necessary security guarantees for the power station itself, and monitor various objects such as environmental conditions, key equipment, and key locations, so that the power station can be truly unattended.

Wintop OpticalSolutions

There are 31 box transformers at the Donglao Photovoltaic Power Generation Site in Gengma County, 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 optical fiber ring network adopts a protection mechanism to effectively prevent network failures caused by fiber damage and achieve self-healing time of the ring network< ;20ms. In addition, because some equipment in photovoltaic power stations will produce a strong electromagnetic field, high requirements are placed on the electromagnetic compatibility of industrial switch equipment in communication networks. Wintop Opticalindustrial switches have passed the EMC industrial level 4 electromagnetic compatibility standard certification and are equipped with abundant optical fiber ports. Since optical fibers are basically not interfered by electromagnetic fields, they have long transmission distance and high bandwidth, which can effectively resist the strong electromagnetic interference of wind farms and ensure that the system operates in It operates stably and reliably in harsh environments and has been widely used in the photovoltaic power generation industry.
