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(yìn)度(dù)客戶計劃(huá)自(zì)己(jǐ)生產(chǎn)逆變(biàn)器。他們需要電表配套(tào)逆(nì)變(biàn)器(qì)做(zuò)政(zhèng)府(fǔ)招標項目。他們(mén)需(xū)要(yào)ACR10R來(lái)監控(kòng)工(gōng)廠(chǎng)設備的(dí)用(yòng)電(diàn)量，並(bìng)使(shǐ)用電(diàn)表合理(lǐ)地檢測(cè)每(měi)個設備(bèi)的(dí)能耗(hào)，同時AWT100-4G使用MQTT協議(yì)上傳(chuán)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

ACR10R具(jù)有多種(zhǒng)外(wài)圍接口功能可(kě)供(gōng)用戶選(xuǎn)擇(zé)： 帶(dài)有RS485通訊(xùn)接(jiē)口(kǒu)， 采用MODBUS-RTU協(xié)議(yì)可滿(mǎn)足通訊聯網管(guǎn)理(lǐ)的(dí)需(xū)要； 帶開(kāi)關量(liáng)輸入和(hé)繼電(diàn)器輸(shū)出(chū)可實(shí)現(xiàn)斷路器開(kāi)關的(dí)“ 遙(yáo)信" 和(hé)“ 遙控(kòng)" 的功(gōng)能， 采用LCD顯示(shì)界麵， 通(tōng)過麵板(bǎn)按鍵來(lái)實(shí)現(xiàn)參(cān)數(shù)設置和控(kòng)製(zhì)非常適合(hé)用(yòng)液晶顯(xiǎn)示器(qì)和麵(miàn)板(bǎn)按(àn)鈕實現(xiàn)參數(shù)的設(shè)置和控(kòng)製(zhì)的(dí)光伏逆變器係統。

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.
