Huawei Smart PV Remedy Highlights Role In World's Largest PV Plant

• On September 26, Chinese state-owned utility Huanghe Hydropower Development ("Huanghe Hydropower") effectively linked its 2.2 GW PV plant to the power grid in Hainan Prefecture, northwestern China's Qinghai Province. With this, the 2.2 GW project became the world's very first ultra-high voltage power line that delivers 100% renewable energy over long distances as well as additionally the globe's biggest single-site renewable resource project constructed in the quickest construction time.

For Huanghe, the milestone project was a prominent project not just in regards to size, yet tool selection, building and construction criteria, and modern technologies. The company, which collaborates with multiple companions to support as well as construct a solid environment for research study as well as development, the partnership with Huawei was constantly going to be critical, thinking about Huawei's leadership in the inverter, and also specifically the string inverter area.

The grid-connected 2.2 GW PV plant lies in Qinghai Province at an average elevation of over 3000 m. Built in 5 stages, it includes 672 PV selections with over 7 million PV components. 3 330 kV booster terminals were constructed as well as string inverters were set up. The cool, dry desert like conditions were taken into consideration optimal or solar power generation.

Huawei asserts to have actually provided 1.6 GW inverters for this project, making it the solitary biggest supplier. As the globe's initial ultra-high voltage high-voltage line that delivers 100% renewable energy over cross countries, the project requires inverters with high voltage ride-through (HVRT) ability to make sure the safety and also security of the power grid. Being the very first to pass the GB/T 37408-2019 technological demands for solar grid-connected inverter, Huawei's cases that its clever string inverter supports short circuit proportion (SCR) as reduced as 1.5, without power derating throughout HVRT. It can also connect to weak grids and uses mistake ride-through capacity, assuring steady procedure in numerous grid atmospheres.

Besides innovative inverters, this project additionally makes use of the advantages of several smart modern technologies, such as MBUS power service providers, Smart I-V Curve Diagnosis 4.0, clever electro-luminescence (EL) discovery, incorporated application of trackers, bifacial PV modules, and also wise inverters, and wise PV plant management. These substantially optimize O&M efficiency, facilitate precise fault forecast, and also lessen the levelized price of power (LCOE). With joint development, Huanghe Hydropower as well as Huawei established the industry-leading smart I-V diagnosis technology for global PV O&M, which has been commonly taken on worldwide.

The Huanghe project, and several other joint projects, have had a considerable effect on the screening, development, and presentation of both house grown and also global modern technologies in China. The range of this project, and also the understandings from it could conveniently affect worldwide finest techniques for a long time to come.
