High-altitude "miracles"! Eaton helps connect the world's first million-kilowatt hydro-solar hybrid power plant to the grid

A few days ago, the first phase of the Kola photovoltaic power station in Ganzi Prefecture, Sichuan Province, was officially connected to the grid for power generation, becoming the world's largest and highest altitude "water and light complementation" project. The first phase of the Kola photovoltaic power station is the world's first million-kilowatt hydro-solar hybrid power station, with an average annual power generation of 2 billion kilowatt hours and an annual carbon emission reduction of more than 1.6 million tons, exploring a new path for the integrated development of water, wind and solar in the world.

Eaton gave full play to its successful practical experience in the field of new energy circuit protection, and provided the IZM6 customized air circuit breaker for the new energy industry for the Kola Phase I photovoltaic power plant, helping the project become a new model for the large-scale centralized development of renewable energy integration with excellent safety and reliability, environmental adaptability, intelligent operation and maintenance.

Chasing light new energy helps photovoltaic power stations reduce costs and increase efficiency

The Kola Phase I photovoltaic power station has an installed capacity of 1 million kilowatts, and is connected to the Lianghekou Hydropower Station with an installed capacity of 3 million kilowatts, and the site is located in the plateau area of high cold, high altitude and low atmospheric pressure, with a maximum altitude of 4,600 meters. The harsh natural conditions have extremely strict requirements for the reliability of the photovoltaic power distribution system, and also bring great challenges to the stable operation and daily maintenance of the equipment. Eaton's IZM6 series air circuit breakers on the photovoltaic side of the project won the iF Design Award, bringing more value to customers than expected.

Excellent breaking capacity to escort the safe operation of the power station

In the distribution system of photovoltaic power station, common problems such as abnormal current and abnormal overheating can easily cause short circuit in the battery, which puts forward higher requirements for the breaking capacity of photovoltaic power distribution system equipment.

Eaton's IZM6 series air circuit breaker has an excellent breaking capacity of 1140Vac/66kA(1s), and Icu=Ics=ICW(1s), that is, the operating breaking capacity, the ultimate breaking capacity and the short-time withstand current are equal, so the system does not need to replace components even if it experiences fault current, which can provide safety guarantee for the continuity of power supply in scenarios such as the inverter of the Kola Phase I photovoltaic system and the low-voltage cabinet of the box transformer.

Innovative product materials are not afraid of the harsh environment of the plateau

In the plateau area, the ultraviolet rays are strong, the temperature difference between day and night is large, and it is easy to condensate, and the shell frame of the conventional air circuit breaker cannot adapt to the harsh climate environment, and the long-term low temperature will cause irreversible damage to the plastic parts and mechanisms of the circuit breaker.

Eaton's IZM6 series air circuit breakers feature an LCD-less tripper and optimized material properties for stable operation even at 5,000 meters above sea level and minus 25°C. At the same time, Eaton has taken into account that the long-term operation of the inverter and the box transformer low-voltage cabinet will cause the protection to be weakened, so the unique electroplating process is used to form a perfect protection system for the product to ensure excellent insulation performance in dusty and humid environments.

Intelligent operation and maintenance of power distribution Efficient transmission of new energy

The scale of the first phase of the Kola photovoltaic power station project is huge, the distribution system is widely distributed, and the number of equipment is large, which makes it difficult to locate and troubleshoot faults. Once the operation and maintenance personnel cannot discover, locate and deal with it on site in time, it may cause continuous short circuit or even cause fire

Eaton's IZM6 series air circuit breakers have a built-in intelligent electronic trip unit PXR, which can provide accurate measurement and acquisition of current, voltage, power and other parameters, and can be connected to the intelligent power distribution management platform of the entire project, so that users can keep track of the operation status of the power distribution system at any time. Its multiple protection functions such as voltage protection, frequency protection and leakage protection can help customers ensure the performance of the power distribution system in complex scenarios of photovoltaic power plants, making the operation and maintenance of power stations more efficient and intelligent.

On the road to the "dual carbon" goal, Eaton is committed to integrating digital and new energy technologies to help build a new power system on both the supply and demand sides. In the future, Eaton will continue to work with Kola PV Power Station to fully develop renewable energy and protect the ecology, inject a steady stream of scientific and technological impetus into China's sustainable development, and contribute to accelerating the transformation of China's energy industry.
