With the support of the "12th Five-Year Plan" and "863 Program", the integrated design and integration of large-scale photovoltaic (grid-connected and micro-grid) system design and research and development of advanced energy technologies Research and development of key equipment "and" on-site testing and demonstration demonstration of photovoltaic systems and balancing components "made significant progress and recently passed the technical acceptance. The main objective of this project is to develop world-class PV system integration and engineering technology, complete set of key equipment, build a demonstration project such as 100 MW power station, build an international demonstration demonstration base for photovoltaic systems and balance components, Large-scale use and become a photovoltaic powerhouse to provide technical support.
"Research and Key Equipment Design for Integrated Design of 100MW Solar System" successfully developed 2 kinds of megawatt photovoltaic grid-connected inverters based on parallel connection of IGBT devices and parallel connection of internal modules; developed 2MW / 1MW / 0.5 MW-class photovoltaic system module unit, developed a large-scale photovoltaic grid-connected power station engineering design software; built in Qinghai, Hainan Province, Republican 110 MW grid-connected photovoltaic power plant has been successfully grid-connected power generation.
The field test and demonstration demonstration of PV system and balance components has realized the technical integration of the demonstrative platform of PV system and balanced components demonstration. In Qinghai Republic, 11 kinds of PV modules and 9 system operation modes have been completed, with a total installed capacity of 5.16 MW China's first cold (plateau) climate state-level photovoltaic system and balance of parts of the empirical research base; built China's first MW-level photovoltaic system and balance components of the public test platform, the maximum test capacity of 1MW; developed Modular mobile photovoltaic system test platform, and has carried out on-site testing of a number of domestic PV power station; developed 100kW-1.5MW level PV grid-connected inverter research and test platform access to China National Accreditation Board for Conformity Assessment (CNAS) Recognized.
The research results obtained from the project can provide technical support for the development of large-scale photovoltaic power plants of megawatts and gigawatts in the country. Established in Qinghai with advanced level demonstration of photovoltaic systems and balanced components demonstration base for a variety of different types of PV modules, systems and components to carry out long-term empirical research test, and provide the industry for third-party fair field environment Public testing can provide research and demonstration test for the large-scale utilization of centralized photovoltaic technology in the western part of China, and provide field and real technical support for the research and development of new PV technologies and new products. And for different types of applications to establish empirical research demonstration test to provide technical support, accumulated valuable experience.
