Key Technology And Application Study On Large Scale Grid-connected Photovoltaic Power Plant

Along with the worldwide energy shortage of energy and environmental pollution, the renewable energy especially solar energy will play a key role due to its non-pollution, easily to construct and maintain. The planning and development of photovoltaic power technology is becoming the most important measurements on PV industry all over the world, especially in China.Focus on large scale photovoltaic power system, this paper analyzes the system composition and grid connected systems of PV power station. Taking Gansu 10MW PV project and Shanghai Nanshi 523kW PV plant as examples, the basic framework of large scale PV grid connect systems is presented and some problems in engineering design and implementation process are highlighted which should be pay more attention to in the future.
