Abstract

[Objective] A digital-physical hybrid simulation can accurately simulate the actual operating characteristics of a high-voltage direct-current （HVDC） transmission system. However， an interface module between the digital and physical subsystems is crucial for system stability and precise simulations. Because of the differences in direct current （DC） system characteristics under various conditions， the existing algorithms are not uniformly applicable. This paper presents a damping impedance interface algorithm based on adaptive switching and degree of disturbance.[Methods] First， a compensation impedance-switching method and criteria are proposed based on impedance and performance characteristics. Subsequently， the calculation methods for the equivalent impedance in the steady state and compensation impedance in the transient state are presented. Finally， a hybrid simulation model is built and the interface characteristics are verified.[Results] The results achieved higher stability than the ideal transformer method and a relative error of less than 1.5% in the steady state， indicating good accuracy.[Conclusions] The proposed adaptive switching method significantly expands the applicability range of the damping impedance approach， offering a novel solution for the digital-physical hybrid simulation of HVDC transmission systems.

摘要

相较传统电力系统,含新能源的交直流混联系统结构更加复杂,其稳定评估难度更大,且稳定影响因素的甄别和解释性较差。针对上述问题,首先选择新能源和直流特征量作为稳定评估模型的输入,并由sigmoid函数得到样本预测值与稳定结果之间的关系,提出一种基于极致梯度提升树(extreme gradient Boosting, XGBoost)的交直流混联系统暂态功角稳定评估方法;为进一步分析特征量对系统暂态功角稳定的影响,提出基于SHAP(Shapley additive explanations)的特征量可解释分析方法,从全局说明新能源和直流特征量的重要性,并从全部样本的角度反映各特征量值本身的大小与稳定结果的促进和抑制关系,再从局部得到特征量对单个样本稳定结果的影响;最后在某500 kV实际交直流混联系统上进行仿真验证,证实了该评估方法的准确率较高且SHAP能有效解释新能源和直流特征量对交直流混联系统暂态功角稳定的影响。

摘要

Compared with traditional power systems, the structure of an AC/DC hybrid system with new energy sources is more complex, its stability evaluation is more difficult, and the identification and interpretation of stability influencing factors are poor. Given the above problems, this study first selects new energy and DC features as the input of the stability evaluation model and obtains the relationship between the sample prediction value and the stability result using the sigmoid function. A transient power-angle stability evaluation method for an AC/DC hybrid system based on extreme gradient Boosting (XGBoost) was proposed. To further analyze the influence of features on the transient power angle stability of the system, an interpretable analysis method of features based on SHAP is proposed, which explains the importance of new energy and DC features from a global perspective, which reflects the relationship between the size of each feature itself and the promotion and inhibition of stability results from the perspective of all samples, and then obtains the influence of features on the stability results of a single sample from a local perspective. Finally, simulation verification was performed on a 500 kV actual AC/DC hybrid system, which proves that the accuracy of the evaluation method is high and that SHAP can effectively explain the influence of new energy and DC features on the transient power angle stability of the AC/DC hybrid system.

摘要

特高压直流输电系统直流闭锁故障及交流系统短路故障引起的暂态过电压,对系统稳定性造成严重冲击。量化评估交直流系统暂态性能指标,对确定交直流电力系统规划设计和调度运行具有指导意义。对交流系统暂态过电压机理进行分析,推导出基于无功补偿和短路比的暂态过电压计算方法,基于系统短路比与补偿电容和交流滤波器参数的比值定义了暂态电压评估指标Rr。研究表明,随着该暂态电压评估指标Rr减小,系统故障后送端换流母线暂态电压升高,受端也会发生不同程度的换相失败。最后,基于国际大电网会议直流标准测试系统,验证了所提指标的有效性。

摘要

The transient overvoltage caused by the DC blocking fault of the UHVDC transmission system and the short-circuit fault of the AC system has a serious impact on the stability of the system. Quantitative assessment of the transient performance index has important guiding significance for the dispatching operation of AC/DC power system. This paper analyzes the mechanism of transient overvoltage in AC system, deduces the calculation method of transient overvoltage on the basis of reactive power compensation and short-circuit ratio, and then defines the transient voltage evaluation index Rr. Research shows that, as the index Rr decreases, the transient voltage of the commutation bus at the sending end will increase after a system fault, and commutation failures will also occur at the receiving end. Finally, on the basis of the CIGRE benchmark HVDC standard test system, the effectiveness of the proposed index Rr is verified.
