含高比例新能源的电网换相换流器型高压直流(LCC-HVDC)系统馈入弱受端电网时存在宽频振荡风险,故有必要对LCC-HVDC受端系统进行快速有效的宽频阻抗测量以分析其运行稳定性。文中避开了介入型阻抗测量方法带来的稳定性等问题,首先,基于谐波状态空间理论所建立的LCC-HVDC系统非介入型阻抗测量模型,利用直流传输功率的变化设计了一种变步长指标以反映系统的运行状态;然后,以类箕舌线函数作为变步长的适配母函数,多维度剖析母函数得到自适应变步长因子,以实现采样步长的实时更新,优化阻抗测量系统的算力;同时,引入数据压缩比与计算时间缩减百分比指标,对比分析自适应变步长与传统固定步长快速有效捕捉系统失稳的能力;最后,利用CIGRE标准模型算例验证了所提方法在宽频阻抗测量中的有效性。
When a line commutated converter-based high-voltage direct current (LCC-HVDC) system with high proportion of renewable energy feeds into a weak receiving-end power grid
there exists a risk of wide-band oscillation. Thus
it is essential to conduct rapid and effective wide-band impedance measurements on the LCC-HVDC receiving-end system to analyze its operation stability. This paper circumvents the issues such as stability problems associated with intrusive impedance measurement methods. Firstly
based on the non-intrusive impedance measurement model of the LCC-HVDC system established by using the harmonic state space theory
a variable-step index is designed by leveraging the variation in DC transmission power to reflect the system operation state. Secondly
the versoria-like function is employed as the adaptive mother function for variable steps. Through multi-dimensional analysis of the mother function
an adaptive variable step factor is derived to achieve real-time updates of the sampling step
thereby optimizing the computing power of the impedance measurement system. Meanwhile
the indicators such as the data compression ratio and the percentage reduction in computation time are introduced to comparatively analyze the capabilities of the adaptive variable step and the traditional fixed step in quickly and effectively capturing system instability. Finally
the effectiveness of the proposed method in wide-band impedance measurement is verified through a case of the CIGRE standard model.
