| 摘 要： | 大规模高压直流输电的飞速发展、分布式电源和电动汽车的高渗透接入，使得送端电网中谐波污染日益严重。送端电网的谐波由过去的低次谐波为主、特定次谐波含量较多的特点向宽频次转化。对以新疆电网为例的送端电网中火电、水电、风电及光伏发电等电源进行机理分析，确定了火电和水电可当作理想电源，而风电及光伏发电为谐波源。并分析了送端电网中的各类负荷，得到其谐波特性。继而，分析了谐波在各电压等级间的传递特性、多谐波源叠加机理以及不同电压等级间谐波相互作用机理。最后，利用ETAP软件对新疆电网中的谐波特性进行了仿真分析，验证了所归纳的送端电网谐波特性的正确性。

| Abstract: | With the rapid development of large-scale HVDC transmission and the high penetration of distributed generation and electric vehicles, the harmonic pollution in sending-end power grid is increasingly serious. The harmonics in the sending end power grid are transformed from low-order and containing more specific order harmonics to broadband harmonics. The paper analyzes the mechanism of thermal power, hydropower, wind power and photovoltaic power generation in Xinjiang sending-end power grid, determining that the thermal power and hydropower can be used as ideal power supply, while the wind power and photovoltaic power generation can be regarded as harmonic source. Meanwhile, the various loads in the sending-end power grid are analyzed to obtain their harmonic characteristics; the transfer characteristics and interaction mechanism of the harmonics among different voltage levels as well as the superposition mecha-nism of multiple harmonic sources are analyzed. Finally, the harmonic characteristics of Xinjiang power grid are simulated and analyzed by using ETAP software, verifying the correctness of the harmonic characteristics of the sending-end power grid summarized in this paper. |
