Application of Acrel ACR10R Series with AWT100-4G in PV inverters in India

摘要：太陽能是世界上快速增長的能源，也是較容易獲得的可再生能源,采用太陽能向電網(wǎng)輸電市場份額不斷增長。同時電網(wǎng)公司通常要求光伏并網(wǎng)系統(tǒng)為不可逆流發(fā)電系統(tǒng)，即光伏并網(wǎng)系統(tǒng)所發(fā)的電由本地負(fù)荷消耗，即自發(fā)自用。在并網(wǎng)發(fā)電和儲能系統(tǒng)中，由于外部環(huán)境是不斷變化的，為了防止光伏并網(wǎng)系統(tǒng)逆向發(fā)電，系統(tǒng)需要進(jìn)行逆流檢測，通過實(shí)時監(jiān)測配電變壓器低壓出口側(cè)的功率信號來調(diào)節(jié)系統(tǒng)的發(fā)電功率，從而達(dá)到光伏并網(wǎng)系統(tǒng)的防逆流功能。本文介紹了安科瑞 ACR10R與AWT100-4G在印度某泵行業(yè)的應(yīng)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. 項(xiàng)目概述 Project Overview

印度客戶計劃自己生產(chǎn)逆變器。他們需要電表配套逆變器做政府招標(biāo)項(xiàng)目。他們需要ACR10R來監(jiān)控工廠設(shè)備的用電量，并使用電表合理地檢測每個設(shè)備的能耗，同時AWT100-4G使用MQTT協(xié)議上傳平臺。

   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
