Summary of 1MW Solar Gridconnected Power Station System 在公共電網(wǎng)已經(jīng)存在，但電力不足地區(qū)，可采用部分太陽(yáng)能并網(wǎng)發(fā)電，提高電網(wǎng)供電可靠性和供電能力。 發(fā)電系統(tǒng)的實(shí)時(shí)發(fā)電功率由太陽(yáng)輻照度決定。負(fù)載優(yōu)先使用太陽(yáng)能產(chǎn)生的電力，其余不足部分由公共電網(wǎng)補(bǔ)充。 并網(wǎng)系統(tǒng)只 可作為一種補(bǔ)充性能源，而不能作為后備或主要電力，其發(fā)電量相對(duì)已有發(fā)電系統(tǒng)的總發(fā)電量而言，一般比重不應(yīng)超過(guò) 20%；而且對(duì)并入的電網(wǎng)質(zhì)量，如電壓穩(wěn)定性，頻率穩(wěn)定性等有較高要求。同時(shí)該系統(tǒng)只在白天有光照的情況下工作，而且由于其保護(hù)功能，電網(wǎng)停電時(shí)，系統(tǒng)內(nèi)的并網(wǎng)逆變器與電網(wǎng)斷開(kāi) ，并網(wǎng)系統(tǒng)也同時(shí)停止工作 。 The region with public power grid and insufficient electrical power can use solar energy gridconnected power generation partially to improve the reliability and capacity of power supply. The realtime generated power of the system is determined by solar irradiance. 設(shè)計(jì)單位：保利深遠(yuǎn)（北京）新能源科技有限公司 Design anization: Poly Shenyuan (Beijing) New Energy Technology Co., Ltd. 項(xiàng)目設(shè)計(jì)技術(shù)信息 —1MW 太陽(yáng)能并網(wǎng)電站發(fā)電系統(tǒng) Technical Information of Project Design—1MW Solar Gridconnected Power Station System 14 The load consumes power generated by solar energy preferably and the shortfall is supplemented by public power grid. The gridconnected system can only serve as a supplementary energy rather than backup or main power. In general, its generating capacity shall not exceed 20% of that of the existing power generation system。 besides, the requirements on the quality of the connected power grid, such as the voltage stability and frequency stability are high. Meanwhile, this system only works in the day with illumination. Since it has the protective function, during power failure of the power grid, the gridconnected inverter is disconnected with the power grid and the gridconnected system stops work. 并網(wǎng)系統(tǒng)不需要蓄電池，所以其系統(tǒng)造價(jià)低于離網(wǎng)型太陽(yáng)能電站。 Since the gridconnected system doesn’t need panel, the system cost is lower than that of the offgrid solar power station. 1MW系統(tǒng)在有效日照 6小時(shí)情況下，系統(tǒng)效率按 ，日均發(fā)電量為 6000kWh，日均可用電量為 4800kWh，年 可用 發(fā)電量約 1752MWh。 Under the effective sunshine of 6 hours and taking system efficiency as , 1MW system has mean daily power generation of 6000kWh, mean daily available power of 4800kWh and annual available power of 1752MWh. 該系統(tǒng)太陽(yáng)能電池組件總面積 約 為 6810平方米，電池方陣占地面積約為 15000 ~ 25000平方米。 設(shè)備房約 150平方米。 The total area of the solar module of this system is 6810m2 and the solar panel covers area of 15000 ~ 25000m2. The equipment room is about 150m2. 二 、 1MW 太陽(yáng)能并網(wǎng)電站 系統(tǒng)組成 II.
