- In digital relay , the percentage of noise will increase rapidly with the increase of sampling rate when derivation calculus is substituted by sampled difference term . to solve this problem , a new method using fragment function integrated with the least square algorithm is proposed in this paper . the influence of white noise is greatly reduced and the accuracy of the dead angle calculation is nicely improved after adopting the new method
在数字式保护中，如果用差分代替求导将导致噪声的百分比误差随着采样频率的提高而剧增，本文对此进行了分析并提出了用分段样条函数最小二乘法来计算电流波形的导数值，以便在提高采样率的同时降低噪声误差的影响，并将其应用于基于32位浮点dsp的新型变压器保护装置。 - The advantages of this system are that the fluxes from the current model are easily obtained , all of the fluxes ( from voltage and current models ) are dc quantities , which are convenient for control and checking , and the system stability is easily analyzed . a further advantage is the avoidance of integration problems
本系统的优点之一是磁通的指令值通过计算电流模型而获得，所有的磁通量（电压、电流模型）都是直流量，便于控制和检查，系统的稳定性易于分析，另一个优点是利用磁通观测器可以避免用电压模型推算磁通时的积分运算问题。 - By using a cell equivalent method , the present model can deal with the face - center square structure of erf . combining the scheme of the classical conductivity model for the single - chain structure , a new formula for the prediction of the shear yield stress of erf is set up . the influences of the separation distance of the particles , the volume fraction of the particles and the applied electric field on the shear yield stress are investigated
在电导模型的基础上，建立在电流变液体在外加电场的作用下，粒子之间会形成某种特定的微观结构，利用等效胞元的方法，将这微观结构等效成一个平板，建立了等效的微观结构平板模型，通过计算电流变液体内部的局部电场，对电流变液体的工作机理和剪切屈服应力进行了预测，并且分别考虑了在不同的粒子间距、不同的粒子浓度、不同的外加电场的情况下，对剪切屈服应力的影响。
