近日，世界首個(gè)具備虛擬同步機(jī)功能的新能源電站在國(guó)家風(fēng)光儲(chǔ)輸示范電站建成投運(yùn)——新能源并網(wǎng)的最大技術(shù)難題就此被一舉攻克。20年來(lái)，發(fā)達(dá)國(guó)家一直在努力攻關(guān)虛擬同步機(jī)技術(shù)，但始終未有實(shí)質(zhì)突破。

我國(guó)率先攻克虛擬同步機(jī)技術(shù)
近年來(lái)，光伏、風(fēng)電等新能源因清潔環(huán)保得到快速發(fā)展，但在不斷優(yōu)化能源結(jié)構(gòu)的同時(shí)，也為我國(guó)電網(wǎng)的安全運(yùn)行帶來(lái)了一定挑戰(zhàn)。在電力系統(tǒng)里，發(fā)電和用電是同時(shí)完成的，即用戶需要多少電，電廠就要發(fā)多少電，如果發(fā)電端無(wú)法與大電網(wǎng)的節(jié)奏保持一致，就會(huì)出現(xiàn)問(wèn)題。

保持用電量和發(fā)電量的動(dòng)態(tài)平衡是電網(wǎng)安全運(yùn)行的關(guān)鍵。為保障新能源大規(guī)模安全并網(wǎng)，就需要用到新能源虛擬同步機(jī)——這一“馴服”新能源的好幫手。

何謂虛擬同步發(fā)電機(jī)技術(shù)？
虛擬同步發(fā)電機(jī)技術(shù)是一種通過(guò)模擬同步發(fā)電機(jī)組的機(jī)電暫態(tài)特性，使采用變流器的電源具有同步發(fā)電機(jī)組的慣量、阻尼、一次調(diào)頻、無(wú)功調(diào)壓等并網(wǎng)運(yùn)行外特性的技術(shù)。更為重要的是，虛擬同步機(jī)并不需要對(duì)電網(wǎng)大規(guī)模改造，不僅實(shí)用性強(qiáng)，還經(jīng)濟(jì)實(shí)惠。

“新能源虛擬同步機(jī)科技示范工程歷時(shí)兩年，是國(guó)家電網(wǎng)公司十大科技創(chuàng)新示范工程之一。”國(guó)網(wǎng)冀北電力有限公司科技信通部主任王葆潔介紹說(shuō)，這一技術(shù)能夠使新能源機(jī)組由“我行我素”的“自轉(zhuǎn)”轉(zhuǎn)變?yōu)?ldquo;協(xié)調(diào)統(tǒng)一”的“公轉(zhuǎn)”，主動(dòng)支撐電網(wǎng)頻率、電壓波動(dòng)，有力保障電網(wǎng)安全穩(wěn)定運(yùn)行。
