Application of Acrel ACR10R Series with AWT100-4G in PV inverters in India
摘要:太阳能是世界上快速增长的能源,也是较*获得的可再生能源,采用太阳能向电网输电市场份额不断增长。同时电网公司通常要求光伏并网系统为不可逆流发电系统,即光伏并网系统所发的电由本地负荷消耗,即自发自用。在并网发电和储能系统中,由于外部环境是不断变化的,为了防止光伏并网系统逆向发电,系统需要进行逆流检测,通过实时监测配电变压器低压出口侧的功率信号来调节系统的发电功率,从而达到光伏并网系统的防逆流功能。本文介绍了安科瑞 ACR10R与AWT100-4G在印度某泵行业的应用。
Abstract: Solar energy is a rapidly growing energy source in the world and the most easily available renewable energy source. The market share of the use of solar energy to transmit electricity to the grid is still growing. At the same time, grid companies usually require the photovoltaic grid-connected system to be an irreversible power generation system, that is, the electricity generated by the photovoltaic grid-connected system is consumed by the local load. It is self-generated and used. In the grid-connected power generation and energy storage system, with the external environment is constantly changing, in order to prevent the photovoltaic grid-connected system from generating reverse power, the system needs to perform reverse current detection, and regulate the power generation of the system by real-time monitoring of the power ** on the low-voltage outlet side of the distribution transformer power, so as to achieve the anti-backflow function of the photovoltaic grid-connected system. This article introduces the application of ACREL ACR10R and AWT100-4G in a pump industry in India
