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，也是较容易获得的可再生能源,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 signal 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

1. 项目概述 Project Overview

印度客户计划自己生产逆变器。他们需要电表配套逆变器做政府招标项目。他们需要ACR10R来监控工厂设备的用电量，并使用电表合理地检测每个设备的能耗，同时AWT100-4G使用MQTT协议上传平台。

   Indian customers plan to produce inverters by themselves. They need inverters and energy meters for government tender. They need ACR10T to monitor the electricity consumption of the plant equipment and use electricity meters to detect the energy consumption of each device effectively. AWT100-4G use MQTT protocol to connect the platform

6.结束语In conclusion

ACR10R具有多种外围接口功能可供用户选择： 带有RS485通讯接口， 采用MODBUS-RTU协议可满足通讯联网管理的需要； 带开关量输入和继电器输出可实现断路器开关的“ 遥信” 和“ 遥控” 的功能， 采用LCD显示界面， 通过面板按键来实现参数设置和控制非常适合用液晶显示器和面板按钮实现参数的设置和控制的光伏逆变器系统。

ACR10R it has a variety of peripheral interface for user to choose: with RS485 communication interface, MODBUS-RTU protocol can meet the needs of communication network management; The function of “ remote signal” and “ remote control” of circuit breaker switch can be realized with switch quantity input and relay output. The interfaces with switch input and relay output can realize the remote signaling and remote control of the circuit breaker switch. It is very suitable for real-time power monitoring system with an LCD display and the panel buttons to realize the setting and control of parameters for PV inverter system.
