摘 要:以南通沿海風電場對電網的影響為例,分析了因風電導致電能質量問題的產生機理,并利用現場測試數據進行了考核。結果顯示,風電出力的隨機性和波動性給電網的運行控制帶來了不確定性,且造成各種電能質量問題。提出了若干應時措施,以期降低風電接入系統后對電能質量的影響,保證沿海風電大規模接入后電網的安全、穩定、經濟運行。
關鍵詞:沿海風電;電能質量;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
