Wintop Optoelectronics assists the construction of Ningxia energy storage power station project

 In response to the challenge of global climate change, the goal of carbon neutrality for green, low-carbon and sustainable development has become a global consensus. Building a new power system based on renewable energy is an important path to achieve carbon neutrality. Renewable energy sources such as solar energy and wind energy have been widely used. However, these energy sources are intermittent, volatile, and uncertain, which will make it difficult to ensure the balance between power supply and demand. Energy storage technology can increase the proportion of renewable energy consumption. Reduce the impact on the power grid and improve the flexibility, economy and security of the power system. The development of energy storage technology is a necessary condition for promoting the transformation of energy structure!

With the continuous innovation and progress of energy storage technology, the growth of electricity market demand and the upgrading of energy structure, the global energy storage industry has ushered in a good opportunity for rapid development, and Chinese energy storage enterprises are also ushering in the peak period of development.

Energy storage power station project introduction

The project has a total investment of about 800 million yuan, a total construction capacity of 200MW/400MWh, and an annual average charge and discharge capacity of more than 100 million kWh. It is the largest single grid-side shared energy storage project in Ningxia. The energy storage power station is arranged in an outdoor prefabricated cabin. Through efficient battery energy storage technology, it carries three kinds of lithium iron phosphate batteries with different capacities to realize large-scale storage of electric energy and release the power supply system for use when needed.

The main functions of the energy storage power station include energy storage, regulation and backup functions, and the peak and valley regulation of the power system and the provision of emergency backup power can be realized through a flexible energy management system. As the "power bank" of the power grid, after the energy storage power station is completed, it will further enhance the flexible adjustment ability of the power grid, effectively realize the peak-shaving and valley-filling of the power grid, relieve the peak power supply pressure, promote the consumption of new energy, reduce the volatility of energy supply, reduce the Reliance on traditional fossil energy is of great significance for accelerating the application of Ningxia’s large-scale energy storage in power peak regulation and renewable energy power grid integration, providing data support for Ningxia’s large-scale energy storage construction, and consolidating multi-energy complementary energy sources supply pattern.

The whole project mainly includes energy storage system, inverter system, control and monitoring system, power transmission system, security system and communication system, etc. According to the actual situation of the project and the construction needs of major systems, Wintop Optoelectronics provides PCS inverter system, BMS The battery management system and EMS background scheduling management system provide an effective intelligent monitoring network solution to help the project realize the visualization, systematization and efficiency of management

project challenge

Deserts, Gobi, and desert areas are the "main battlefields" for new energy construction. This project is located in Ningxia, Northwest my country, where the natural environment is relatively complex and harsh. Since the energy storage power station works in an outdoor environment for a long time, the temperature difference changes greatly, there are many moisture, salt spray and sand dust, and it has long been affected by special environments such as high altitude, low temperature, and strong wind and sand. At the same time, the independent communication of the system and the stable operation of the equipment will be affected to a certain extent.

project requirements

The whole solution needs to meet the requirements of the field environment, so that the industrial switch can work stably and reliably in the harsh environment.

It is necessary to realize remote centralized management and control, collect and exchange various information in real time.

It can ensure the timeliness and accuracy of monitoring information, and provide strong technical support for the transmission of front-end current, voltage, temperature and other data information to the background and efficient management

solution

The energy storage power station has 69 energy storage cabinets. Wintop Optoelectronics installs 4 RS6110-2GF8GT rail-mounted industrial switches in each energy storage cabinet and connects to CM6028-4GF24GT rack-mounted industrial switches to form 8 ring networks.

In the data link layer, in order to improve the speed, the GOOSE message of the RS6110-2GF8GT switch adopts the VLAN tag protocol, and the content indicating the priority is added to the data, and the RS6110-2GF8GT industrial Ethernet switch supporting the VLAN tag Real-time processing ensures its real-time characteristics.

The RS6110-2GF8GT gigabit switch is used in the energy storage cabinet, which has the characteristics of high bandwidth, high stability and high real-time performance, and stably transmits the connected BMC battery data, measurement and control data, and PCS communication data to the CM6028-4GF24GT aggregation switch. Send data to the background.

RS6110-2GF8GT and CM6028-4GF24GT industrial switches support a wide temperature range of minus 40-85°C, millisecond-level de-ring time advantages, and industrial performance such as IP40 shell protection, EMC industrial level 4 electromagnetic compatibility, and redundant dual power supply design, fully meeting Industrial site requirements in special environments such as high altitude, low temperature, and strong sandstorms where the project is located.

Energy storage is a key link in the transformation and development of green energy, and it is an important technical support for achieving the "dual carbon" goals of carbon peaking and carbon neutrality. The development and maturity of the energy storage industry is crucial for accelerating the construction of a new energy-based power system Significant and future. Wintop Optoelectronics has been thoroughly implementing the concept of green and low-carbon circular development with practical actions. We will continue to increase and empower the high-quality development of my country's energy storage industry with our excellent R&D strength, reliable product strength and excellent service support. The "Double Carbon" goal contributes to the strength of the enterprise!
