“This is not a simple product iteration, but a disruptive breakthrough in power electronics technology! “Yin Pengfei, chief engineer of New Scenery, introduced to everyone that the new generation SST integrates voltage conversion, electrical isolation, bidirectional power control, power quality management and intelligent scheduling, and realizes independent research and development from topology architecture, drive design to core control algorithm and manufacturing process. Its high-pressure side variable flow technology and the company’s large-scale commercial high-pressure SVG, high-pressure cascade storage products are the same, reliability by the massive engineering scene long-term strict test.
the key leap from technology pre-research to achievement transformation in 20 years
the successful downline of the new scenery SST is behind 20 years of deep technological cultivation.
As early as 2006, Xinfengguang participated in the national 863 plan project, took the lead in laying out the research and development of the core technology of solid-state transformers, and successfully solved the key problems in the industry such as high-frequency isolation transformation, bidirectional power millisecond-level precise control, and power grid condition adaptation. In the domestic 10kV distribution network scene landing “two-way H-bridge cascade extension and high-frequency isolation transformer” technical scheme, gradually master the core technology, established the basis of continuous product innovation.
from laboratory technology to industrialization landing, the new scenery has completed a magnificent turn from “technology chasing” to “independent leading”, realizing the key leap from pre-research to engineering of new power system core equipment.
Performance Leading Three Advantages Enabling New Power Systems
Energy Efficient and Lower Loss. Using advanced power electronic technology, the conversion efficiency exceeds 98%, saving 3%-5% compared with the traditional scheme, and saving more than 10 million kilowatt-hours of electricity annually in large data centers, thus truly realizing low-carbon and efficient operation.
Smart, flexible and adaptable. The input side has the network function and unit redundancy design, the voltage coverage to 13.8kV, can actively support the grid voltage frequency, millisecond response to grid fluctuations, perfect adaptation to the high proportion of new energy grid, AC and DC hybrid distribution network complex scenarios.
Highly integrated and fully functional. One device has multiple functions such as voltage conversion, power quality management, intelligent scheduling, etc. The volume and weight are reduced by about 50% compared with the traditional scheme, thus greatly saving the occupied space.
full-scene enabling energy transformation and AI new infrastructure
AI computing center/data center: creating a low-carbon power supply base. It closely follows the demand of “East-West Calculation” and AI large-scale model calculation force explosion, provides high-grade uninterrupted power supply, comprehensive management of harmonic reactive power, dynamic load allocation services, and cooperates with AI energy efficiency algorithms to greatly reduce power supply losses.
Smart distribution network/new energy: smooth grid-connected flexible regulation. Solve the voltage fluctuation and two-way trend problems brought about by high proportion of new energy access, realize the smooth output of new energy, the flexible regulation of the power grid, and perfectly adapt to the integrated scene of distributed photovoltaic, microgrid, virtual power plant and optical storage and charging.
Rail Transit/New Transportation: New Green Power Supply Scheme. Applied to rail transit traction, port power, electric vehicle overcharge cluster, to solve the problem of high-power impact load grid disturbance, improve energy efficiency and power supply quality.
strategic layout: deep plowing core technology, serving the “double carbon” goal
The successful offline of the new generation of SST is the accumulation of new scenery technology, but also an important strategic layout for the new power system and AI new infrastructure.
in the future, new scenery will continue to deepen the core technology of power electronics, accelerate the engineering iteration and commercialization of SST products, continuously improve the core equipment matrix of new power systems, and continuously contribute hard core technology and equipment strength to the realization of China’s “double carbon” goal, the construction of new power systems, and the high-quality development of artificial intelligence!
