2弱交流电网条件下VSC-HVDC改进矢量控制方法显示文摘当电压源换流器型直流输电(voltage source converter based high voltage direct current transmission,VSC-HVDC)联接弱交流电网输送功率接近交流电网静态稳定极限时,经典矢量控制方法无法保证换流器稳定运行。文中分析VSC联接于弱交流电网时的潮流特性,研究经典矢量控制外环在弱交流电网条件下的特性,通过基于小信号模型的极点分析研究导致换流器无法稳定运行的原因,基于VSC联接于弱交流电网时的失稳机理提出一种改进矢量控制方法,在矢量控制外环增加前馈支路,增加暂态无功响应速度,提高弱交流电网条件下VSC在输送功率接近交流电网静态稳定极限时的稳定性。最后,基于小信号建模的极点分析和时域仿真结果验证改进矢量控制方法的有效性。吴广禄 周孝信 李亚楼 梁军 Agusti Egea-Alvarez 彭红英 张星 2017中国电机工程学报2017,37,16:14
3基于数据分解的上海港集装箱吞吐量预测模型显示文摘根据“分而治之”的框架,分别运用经验模式分解(Empirical Mode Decomposition, EMD)算法和季节性自回归积分滑动平均(Seasonal Autoregressive Integrated Moving Average, SARIMA)算法,将月度集装箱吞吐量时间系列数据分解为不同特征的分量,用支持向量回归(Support Vector Regression, SVR)模型分别对各分量进行预测,EMD-SVR模型和SARIMA-SVR模型预测结果的平均绝对百分误差(Mean Absolute Percentage Errors, MAPE)分别为 5.18%和7.26%,与港口实际吞吐量均较为一致,优于SVR模型的8.55%、自回归积分滑动平均(Autoregressive Integrated Moving Average, ARIMA)模型的11.8%和灰色系统(Grey Model, GM(1,1))模型的10.1%,验证数据分解方法在上海港集装箱月度吞吐量预测中的可行性,支持间接性预测模型精度高于直接模型的观点。冯宏祥 GRIFOLL Manel AGUSTI Martinmallofre 郑彭军 2019中国航海2019,42,2:9
4初榨橄榄油中多酚化合物的UPLC-FLD检测及其抗氧化活性研究显示文摘采用超高效液相色谱荧光检测法(UPLC-FLD)检测不同品种初榨橄榄油中6种多酚化合物的含量,并测定样品的总多酚含量及抗氧化活性,同时对多酚组分与抗氧化能力的相关性进行分析。结果表明:色谱条件为采用Cadenza色谱柱(150 mm×4.6 mm,5μm),柱温35℃,以0.1%甲酸-水(A)-乙腈(B)为流动相进行梯度洗脱,荧光光谱激发波长为278 nm,发射波长为339 nm。在此条件下,初榨橄榄油样品中6种多酚化合物可在17 min内得到较好分离,并在较宽的浓度范围内呈良好的线性关系(R2≥0.9995),且精密度高,日内精密度相对标准偏差(RSD)≤4.91%,日间精密度RSD≤5.41%,加标回收结果准确可靠,平均回收率93.42%~119.86%,RSD≤6.26%。不同初榨橄榄油样品中羟基酪醇、酪醇、香草酸、松脂酚及总多酚含量差异较大,而橄榄苦苷和女贞苷含量最低,且样品间差异较小。初榨橄榄油多酚提取物具有良好的抗氧化活性,但不同品种间具有较大差异,ABTS法测定的总抗氧化能力为0.95~2.71 mmol·L^(-1) Trolox,DPPH自由基清除率为7.22%~66.23%,抑制羟自由基能力为13.24~136.06 U·mL^(-1),其中Coratina的抗氧化活性最强,总多酚含量与提取物总抗氧化能力呈显著正相关。李雪 张玉 王君虹 朱作艺 孙素玲 刘志 朱申龙 沈国新 Agusti ROMERO 王伟 2021浙江农业学报2021,33,5:3
5Analysis and Design of Vector Control for VSC-HVDC Connected to Weak Grids显示文摘Voltage source converter based high voltage direct current transmission(VSC-HVDC)is considered one of the most suitable technologies to integrate renewable energies.However,connecting VSC to a weak grid is challenging since traditional vector control tends to become unstable under high power demand conditions.In this paper,an improved vector control method is proposed wherein a feed forward branch based on steady state and small signal analysis of the VSC system is added under weak grid situations.The feed forward branch promotes faster reactive power response,thus enhancing the stability of the VSC system.Since the improved vector control uses the same inner loop as traditional vector control,the proposed method allows for the ability to retain fault current suppression capabilities.Furthermore,the control parameters of the outer loop of the improved vector control need not vary according to the variation of the operating points,which makes it easy to implement.The feed forward branch is implemented by solving a nonlinear equation or through use of a look-up table.The influence of the estimation errors of short circuit ratio(SCR)on the control performance is also studied.The effectiveness of the improved vector control is demonstrated through small signal model analysis and time domain simulations.Guanglu Wu Jun Liang Xiaoxin Zhou Yalou Li Agusti Egea-Alvarez Gen Li Hongying Peng Xing Zhang 2017CSEE Journal of Power and Energy Systems2017,3,2:3
