SNEC 2021 perfect ending! CRRC's intelligent centralized photovoltaic solution won the gold award of gigawatt level


The 15th International Solar Photovoltaic and Smart Energy (Shanghai) Conference(SNEC 2021) and Exhibition concluded on June 5. With smart centralized photovoltaic solutions, CRRC stands out from nearly a thousand enterprises and has won the gold medal of gigawatt in SNEC exhibition, which has brought the exhibition to a successful end.

Intelligent 3.125mw centralized inverter is a star product with unique functions of health management (PHM), safety management, intelligent unit and network reconfiguration, which is created by CRRC Zhuzhou Institute through core technology iteration. Smart energy technologies such as DC energy storage, broadband dynamic damping, adaptive power allocation, fast power control, virtual grid debugging, fault unit isolation and so on are integrated to help optimize the system power cost. The whole machine adopts mature three-level modular design, which can realize the evolution from power conversion to energy management. The design is simpler, the operation and maintenance is more convenient, and the system cost is more economical. Excellent modulation technology ensures that the product efficiency can reach 99.07%, China efficiency is 98.55%, and the harmonic under rated condition is less than 1%.

CRRC Zhuzhou Institute always adheres to taking science and technology as the guide and innovation as the banner to build an independent and controllable complete industrial chain from chip (device) to complete equipment. Based on the concentric technology diversification strategy, relying on Zhuzhou's strong technology precipitation and professional manufacturing platform in the electric drive field of rail transit, CRRC Zhuzhou Institute has built a leading technology photovoltaic converter product with high-speed rail "craftsmanship spirit" and smart photovoltaic. With the effective integration of digitalization and photovoltaic, we will join hands to welcome "carbon neutral".
