1.項(xiàng)目背景Background

隨著光伏行業(yè)的發(fā)展,部分地區(qū)村級變壓器及工業(yè)用電變壓器容量與光伏項(xiàng)目的裝機(jī)容量處于飽和。電網(wǎng)公司要求對后建的光伏并網(wǎng)系統(tǒng)為不可逆流發(fā)電系統(tǒng),指光伏并網(wǎng)系統(tǒng)所發(fā)生的電由本地負(fù)載消耗,多余的電不允許通過低壓配電變壓器向上級電網(wǎng)逆向送電。

With the development of photovoltaic industry, the capacity of village-level transformers and industrial power transformers and the installed capacity of photovoltaic projects are saturated in some areas.The power grid company requires the photovoltaic grid-connected system to be a non-backflow current generation system, which means that the electricity generated by the photovoltaic grid-connected system is consumed by the local load, and the excess electricity is not allowed to be sent to the upper power grid through the low-voltage distribution transformer in reverse direction.

光伏逆變器在將光伏組件產(chǎn)生的直流電變換交流電時,會夾雜有直流分量和諧波,三相電流不平衡,輸出功率不確定性等,目前基本沒有采取合理的治理手段,因此,當(dāng)有發(fā)電功率送往公用電網(wǎng)時,就會對電網(wǎng)產(chǎn)生諧波污染,易造成電網(wǎng)電壓波動,閃變等,如果有許多這樣的發(fā)電源向電網(wǎng)輸電時,會導(dǎo)致電網(wǎng)電能質(zhì)量嚴(yán)重下降。所以這類光伏發(fā)電系統(tǒng)須配套加裝防逆流設(shè)施,來防止逆功率的發(fā)生。

Photovoltaic inverter in photovoltaic components will produce direct current into alternating current (ac), has the dc component and harmonic mixing, unbalanced three phase current, output power of uncertainty, such as the current basic didn't take effective management measures, therefore, when there is power to the utility grid, will generate harmonic pollution to power network, easy cause power grid voltage fluctuation and flicker, etc.,If there are many such power sources to transmit electricity to the grid, the power quality of the grid will be seriously degraded.Therefore, this kind of photovoltaic power generation system must be equipped with anti-backflow current facilities to prevent the occurrence of reverse power.

當(dāng)光伏發(fā)電量大于負(fù)載需求電量時,會產(chǎn)生逆功率。因此,我們需要儀表來判定。逆變器有過功率輸出,再由儀表通過RS485通訊發(fā)出信號和逆變器數(shù)據(jù)交互,調(diào)節(jié)逆變器輸出功率,使其輸出功率和用電功率平衡。

When the photovoltaic power generation is greater than the load demand, the inverse power will be generated.So we need instruments to determine that Inverter has power output, and then by the instrument through RS485 communication signal and inverter data interaction, adjust the inverter output power, so that its output power and power balance.

2.項(xiàng)目概述Project Overview

菲律賓一家做光伏發(fā)電的公司,聯(lián)系到我司,尋找防逆流電表  , 對接協(xié)議合適后, 采購我司的ACR10R-D16TE.

A photovoltaic power generation company in the Philippines contacted our company to look for anti-backflow current meters. After proper connection agreement, we will purchase ACR10R-D16TE from our company.

當(dāng)光伏發(fā)電量大于負(fù)載需求電量時,會產(chǎn)生逆功率。因此,我們需要儀表來判定逆變器有過功率輸出,再由儀表通過RS485通訊發(fā)出信號和逆變器數(shù)據(jù)交互,調(diào)節(jié)逆變器輸出功率,使其輸出功率和用電功率平衡。

When the photovoltaic power generation is greater than the load demand, reverse power will be generated. Therefore, we need an meter to determine that the inverter has over-power output, and then the meter sends a signal through RS485 communication to interact with the inverter data to adjust the output power of the inverter to balance the output power and the electrical power.
