ACREL DJSF1352-RN DC energy meter’s Application in PV power generation equipment in Saudi Arabia

摘要:本文介紹了安科瑞DJSF1352-RN直流電表在沙特小型光伏發(fā)電設(shè)施直流側(cè)的應(yīng)用。主要用于光伏系統(tǒng)中的電流的計(jì)量,通過分流器對電路系統(tǒng)進(jìn)行計(jì)量、通訊和控制等。

Abstract: This paper introduces the application of Acrel DJSF1352-RN DC energy meter in the DC side of a photovoltaic system in Saudi Arabia. It is mainly used to measure the DC current in the photovoltaic system, and cooperate with current shunts to measure, communicate and control the circuit system.

1.項(xiàng)目概述:Project Overview

該公司位于沙特阿拉伯,公司主要在當(dāng)?shù)貜氖滦⌒凸夥l(fā)電中心項(xiàng)目的安裝施工與維護(hù)等業(yè)務(wù)。客戶想要使用直流電表,用于光伏系統(tǒng)中直流側(cè)電流電壓的監(jiān)測計(jì)量、通訊,要求電表具有兩路直流電能測量的功能。

The company is located in Saudi Arabia. The company is mainly engaged in installation, construction and maintenance of small photovoltaic power generation center projects in Bulgaria and surrounding countries. The customer wants to use DC meters and hall sensors or current shunts for monitoring, metering and communication of current and voltage at the DC side of photovoltaic system, and demands that the DC energy meter would be able to measure two channels of DC circuits.

2.DJSF1352-RN/D儀表簡介 DJSF1352-RN/D DC Energy Meters

DJSF1352-RN導(dǎo)軌式直流電能表帶有雙路直流輸入,主要針對電信基站、直流充電樁、太陽能光伏等應(yīng)用場合而設(shè)計(jì),該系列儀表可測量直流系統(tǒng)中的電壓、電流、功率以及正反向電能等。在實(shí)際使用現(xiàn)場,即可計(jì)量總電能,又可計(jì)量規(guī)定時(shí)間段內(nèi)的電能。檢測的結(jié)果既可用于本地顯示,又能與工控設(shè)備、計(jì)算機(jī)連接,組成測控系統(tǒng)。

儀表可具有紅外通訊接口和RS-485通訊接口,同時(shí)支持Modbus-RTU協(xié)議和DLT645-97(07)協(xié)議;可帶繼電器報(bào)警輸出和開關(guān)量輸入功能;根據(jù)不同要求,通過儀表面板按鍵,對變比、報(bào)警、通訊進(jìn)行設(shè)置;具有開關(guān)量事件記錄(Modbus協(xié)議)、編程和事件設(shè)置記錄(645協(xié)議)、數(shù)據(jù)瞬時(shí)和定時(shí)凍結(jié)功能(645協(xié)議)、電壓電流功率大值、小值記錄功能。

DJSF1352-RN rail-mounted DC power meter with double DC input channels, designed for telecommunications base stations, DC charging piles, solar photovoltaic and other applications, this series of meters can measure the voltage, current, power and forward and reverse energy and so on in the DC system.The actual use of the site, you can measure the total power, but also measure the energy within a specified period of time. The test results can be used for local display, but also with industrial control equipment, computers to form a measurement and control system.

The meter can have infrared communication interface and RS-485 communication interface, and supports Modbus-RTU protocol and DLT645-97 (07) protocol at the same time.The meter can have relay alarm output and digital input function;You can set the ratio, alarm, and communication through the meter panel keys according to different requirements.The meter can have event recording of switch (Modbus protocol), programming and event setting records (645 protocol), instantaneous and timing freeze function of data (645 protocol), maximum and minimum value recording function of voltage and current power.
