摘 要:以南通沿海風(fēng)電場(chǎng)對(duì)電網(wǎng)的影響為例,分析了因風(fēng)電導(dǎo)致電能質(zhì)量問(wèn)題的產(chǎn)生機(jī)理,并利用現(xiàn)場(chǎng)測(cè)試數(shù)據(jù)進(jìn)行了考核。結(jié)果顯示,風(fēng)電出力的隨機(jī)性和波動(dòng)性給電網(wǎng)的運(yùn)行控制帶來(lái)了不確定性,且造成各種電能質(zhì)量問(wèn)題。提出了若干應(yīng)時(shí)措施,以期降低風(fēng)電接入系統(tǒng)后對(duì)電能質(zhì)量的影響,保證沿海風(fēng)電大規(guī)模接入后電網(wǎng)的安全、穩(wěn)定、經(jīng)濟(jì)運(yùn)行。
關(guān)鍵詞:沿海風(fēng)電;電能質(zhì)量;影響

Abstract: Taking impacts of Nantong coastal wind power on grid for example, this paper analyzed generation mechanism of power quality problems due to wind power and carried out examination by using site test data. The result shows that the randomness and uncontrollability of wind power output causes uncertainty and various kinds of power quality problems. Some counterpart measures are raised, so as to reduce the impacts on power quality after wind power is connected in the system, to ensure safe, stable and economic operation of grid after coastal wind power connected in large scale.
Key words: coastal wind power; power quality; impact
