摘要
为保障新型电力系统的建设,对电力电子设备谐波对主网的影响进行了分析,分析了主网层谐波的3个主要特征:海量的分布式谐波源接入、线路电容对谐波的放大效应、谐波的远距离传播。上述因素相互叠加,造成了当前主网层的普遍超标现象。在遵循公认的“谁污染、谁治理”的源头治理基础上,对主网层的谐波治理进行了探索,从机理和案例上分析了不同治理措施的优劣,建议当前采用“谁受害、谁治理”的方案实行终端治理,长远应考虑从源头、地区电网、新建主网站点进行谐波的综合治理。
To ensure the construction of the new power system,the impact of power electronic equipment harmonics on main network is analysed.Three main characteristics of harmonics of the main network are analysed:massive distributed harmonic source access,amplification effect of line capacitance on harmonics and long-distance propagation of harmonics.The above factors overlap with each other,causing the current main network to generally exceed the standard.On the basis of following the recognized source control of"who pollutes,who treats",this paper explores the harmonic control of the main network,analyses the advantages and disadvantages of different control measures from the mechanism and case.The scheme of"who suffers,who treats"to implement terminal control is suggested at present and comprehensive harmonic control measures should be considered from the source,region power grid and the newly built main grid stations in the long run.
