摘　　要：随着离岸中远距离海上风电场并网容量越来越大,大量海缆的广泛应用导致海上风电场接入系统后并网点谐波电压以及流过的谐波电流均存在超限问题。为此,分析了海上风电场陆上集控站谐波过大的原因,并对海上风电场有源滤波器的设计方案进行了理论分析,得到了综合治理下的谐波电流及谐波电压均能满足国标要求的结论。最后将高压有源滤波器应用于岱山及嵊泗风电场,通过系统试验证明了其可有效降低并网点的谐波电流电压,验证了理论成果。With the increasing grid-connected capacity of offshore medium-and long-distance offshore wind farms,a large number of submarine cables are widely used.This leads to the problem of harmonic voltage and harmonic current exceeding the limit after offshore wind farms are connected to the system.Therefore,this paper analyzes the reasons for the excessive harmonics in the onshore centralized control station of offshore wind farms,and theoretically analyzes the design scheme of the active filter of offshore wind farms,and draws the conclusion that the harmonic current and harmonic voltage can meet the requirements of the national standard under comprehensive treatment.Finally,the high-voltage active filter is applied to Daishan and Shengsi wind farms.Through systematic tests,it is proved that it can effectively reduce the harmonic current and voltage of the grid-connected point,and verify the theoretical results.
