Photovoltaic inverter integrated with the hottest

The photovoltaic inverter integrated with Siemens SINAMICS products passed the low voltage ride through test of the state electric power academy for the first time in April, 2012, The Beijing Chenyuan CS 500 photovoltaic inverter and the Beijing kunlan solartec central 500 photovoltaic inverter, the system integrator of the large transmission Department of the drive technology group in the industrial business field of Siemens (China) Co., Ltd., have successfully passed the full function test of low voltage ride through in the national energy solar power generation research and development (experimental) center of the National Electric Power Research Institute, This is the first time that the photovoltaic inverter integrated by Siemens' new intelligent SINAMICS S120 product series has passed this test

two system integrators (Beijing Chenyuan and Beijing kunlan) have adopted SINAMICS S120 photovoltaic inverter unit, control unit and software of Siemens large transmission department as core components. The excellent control technology of these core components can not only improve the efficiency of the system, but also effectively suppress the side harmonics, so that the frequency converter has perfect low-voltage ride through ability, so as to ensure the efficient and reliable operation of the system

according to the requirements of the national energy administration and the national power company for photovoltaic power stations to combine power generation, the photovoltaic inverter that combines power generation must have the function of low voltage ride through to ensure the stable operation of electricity, otherwise it is not allowed to combine. Therefore, the low voltage ride through capability of photovoltaic inverter has become another threshold for the bidding of photovoltaic projects after the certification of golden sun

the national energy and solar power research and development (experimental) center of the state electric power academy is the only institution in China with the qualification of low voltage ride through technology certification. The test is based on the technical regulations for connecting photovoltaic power stations and the test procedures for connecting photovoltaic power stations, including the three-phase balanced drop test and each single-phase unbalanced drop test, which need to be carried out under different drop depths and two power points of light load and full load

Siemens large transmission department has many years of experience in the field of industrial drive. Siemens developed a photovoltaic inverter unit specially used for solar energy based on its original SINAMICS inverter hardware platform in 2010

at present, Siemens adopts the mode of cooperation with system integrators in China. Siemens provides the core components of photovoltaic inverters, and integrators provide overall inverters to promote sales in the Chinese market. This business model can greatly reduce product prices and better meet the needs of the Chinese market
