介绍了MIDC系统中两个强大的换流站Vyborgskaya和Rauma之间的谐波相互作用的现场和理论研究结果。结果表明，在一个换流站没有经过适当滤波的谐波电流可以在整个电网中传播，并在远距离的换流站被放大。特别是，高压直流输电Fenno-Scan的调试影响了与Vyborgskaya背靠背相邻的400千伏交流电力系统的电流测量值。对两级谐波过滤系统和单级系统的效率进行了比较。采用了基于网络频率特性的谐波电流在网络中传播的方法。文章还介绍了150赫兹电晕谐波电流对变电站设备的影响。
The results of field and theoretical studies of the harmonic interaction between two powerful converter substations Vyborgskaya and Rauma in MIDC system are described. It is shown that harmonic currents which are not filtered properly at one converter substation can propagate over the power network and be amplified at distant converter substation. In particular, the commissioning of the HVDC power transmission Fenno-Scan has affected the current psophometric value in 400 kV AC power system adjacent to Vyborgskaya back-to-back. The efficiency of a two-level harmonic filtration system is compared with a single-level system. Method of the propagation of harmonic currents in a network based on the network frequency characteristics is used. The paper also describes the influence of the 150 Hz corona harmonic current on the substation equipment.
