在高比例新能源接入配网的背景下，并网变流器与背景扰动交互作用，原次生谐波发射在宽频范围内增大了谐波谐振风险，为此，提出1种计及次生谐波严重度的无差别危险域评估方法和时序谐波风险评估方法。首先，基于谐波放大倍数定义谐波放大严重度指标和次生谐波严重度指标，通过无差别扫频注入方式评估配电网所有节点与支路全频段谐波谐振风险。其次，考虑实际谐波源的时序特性，计及原次生谐波叠加，构建包含超限概率、超限严重度和连续超限概率3个维度的风险等级矩阵，以量化配电网的时序过压过流风险。最后，通过测试案例和实际工程案例验证所提方法的可行性。

Abstract

收起

In the context of a high-proportion of new energy integration into the distribution network, the interaction between a grid-connected converter and background disturbances increases the risk of harmonic resonance due to the emission of primary and secondary harmonics over a wide frequency band. Therefore, an indiscriminate risk-domain assessment method considering the severity of secondary harmonics and a temporal harmonic risk assessment method are proposed. First, based on the harmonic amplification factor, the severity indexes of harmonic amplification and secondary harmonics are defined, and the risk of harmonic resonance in all the nodes and branches of the distribution network across the entire frequency band is evaluated through indiscriminate sweep injection. Second, considering the temporal characteristics of actual harmonic sources and taking into account the superposition of primary and secondary harmonics, a risk level matrix containing three dimensions of over-limit probability, over-limit severity and continuous over-limit probability is constructed to quantify the temporal over-voltage and over-current risks of the distribution network. Finally, the feasibility of the proposed method was verified through a test case and an actual engineering case.
