Search English Electric SEE series centralized PV grid-connected inverter passed low voltage ride through (LVRT) test

Search English Electric SEE series centralized PV Grid Inverter State Grid Electric Power Research Institute National Energy solar power research and development ( experimental ) Center successfully passed the low voltage ride through (LVRT) full-function tests. According to the National Energy Board , the State Grid Corporation of photovoltaic power plants and power generation requirements and grid PV inverters need to have low voltage ride through capabilities.

Low voltage ride through (LVRT) means the grid voltage drop occurs in the case , PV inverter to certain conditions and time range to maintain the grid until the power returns to normal . Low voltage ride through technology is to improve the stability of power system security maximum protection . Test strictly according to the national grid " photovoltaic power plants connected to the grid technical requirements " and " photovoltaic power plants connected to the grid test procedures ," which includes three phase and single-phase unbalance drop features such as drop test items .

    The certification by the national authority, the State Grid EPRI National Energy solar power research and development ( experimental ) all testing centers in each test, the cable series of the British electrical SEE centralizedphotovoltaic inverters have shown excellent performance . The testing and certification that the British electrical SEE cable series high-power photovoltaic inverter in full compliance with the national grid " photovoltaic power plants connected to the grid technology provides that" low voltage ride through capabilities PV power plant stringent requirements .

 SEE - the future of solar energy explorers unceasing Electrical Technology Co., Ltd. Beijing claims Britain is the first to focus on new areas of energy generation and energy recovery of high-tech enterprise , located in the national high-tech park : Zhongguancun innovation demonstration area, is China's new energy industry earlier mastered a number of core technologies, and have complete independent intellectual property rights of enterprises.

As the earliest in the photovoltaic grid-connected inverter independent research and development , production and sales of businesses, cable English Electric in 2002 has independently developed the first set of domestic solar grid inverter into Beijing power grid operation and, subsequently repeated undertake demonstration projects in the solar on-grid and micro- grid field has accumulated a wealth of technical and practical products

Application experience , as well as the domestic photovoltaic industry to flourish and made useful exploration. Decade now , the British electrical cable through thegrid-connected inverter products in different countries, different regions, different network, a large number of applications in different industries , has accumulated a wealth of operational experience in the three-phase grid-connected inverter conversion efficiency , harmonic suppression , adaptability and reliability of products have a more in-depth understanding and validation has been improved and applied to the customer's investment for better protection and appreciation.
