An accurate method of calculating uncharacteristic harmonics in HVDC transmission systems is proposed in the paper. The method is useful in studies on the properties of uncharateristic harmonies, the influence of unsymmetric ac-side voltages on the operation of HVDC transmission system and the design of filters. The results of the study show that uncharacteristic harmonics caused by ac-side unsymmetric voltage are comparable with characteristic har- monics, the parameter of dc filter reactor has significant influence on the uncharacteristic harmonics and unsymmetric receiving end ac voltage may worsen the operating condition of inverters. As a special case, the proposed method can also be used in the calculation and investigation of characteristic harmonics.

谷超豪在[1]中就报告了拟线性正对称方程组边值问题解的存在和唯一性定理,详细的证明发表于[2],在[7]中对此有所改进,所建立的理论适用于非特征的齐次边值的情况。[3]参考了[2],[4]的做法,把[2]的结果推广到拟线性正对称组具某类特征的边值问题中去,但要求边界条件仍是齐次的。本文讨论边界条件是非齐次的,且是非线性的特征边值问题,在这种情况下建立了可微解的存在和唯一性定理。

If for every nondistinguished homomorphism■∈M_0 there exists a domain such that {△_(nl)} is asubsequnce of {△_n}, there exists a positive integer m=m■, suchthat and for every f∈H~∞(D), a_n(f) converges,Let then D is dense inthe space M(D) of maximal ideals of H~∞(D). Our theorem containsall main results in [3], [4], [5].
